Router Tooling, Feed Rates and Cutting Speeds

Tool Geometry

You always want to use the right tool for the job.

Different tool geometries produce different effects and results with the range of materials that can be cut on this machine.

Tool Geometry
Straight Flute	Will not lift material out of cut.
Spiral Flute	Spiral Flute lifts swarf or pushes it towards cut. depending on geometry
Flute Geometry
Single Flute	Single Flute cutters only have one cutting edge. These are good for faster feed rates in softer materials.
Double Flute	Double Flute cutter have cutting surfaces and are good for cutting harder materials at slower feed rates.
Upcut Spiral	The geometry of an upcut spiral draws swarf up and out the top surface providing the best finish on the down side of the material
Downcut Spiral	The geometry of an downcut spiral draws swarf down and out the bottom surface providing the best finish on the upper side of the material.
Compression Cutters	Compression Cutter have both upward and downward spiral geometry that forces swarf both upward and down and produces a clean finish on both upper and under sides of the materials and is particularly useful in applications with laminated materials.
O Flute	Identified by the Half moon shape, OFlute cutters have a single flute that ejects swarf effeciently. As such they are suited to cutting timbers and plastics (softer materials ) at high speeds.

Preflight checks - Vcarve

Before Exporting the NC file for your cutting program from VCarve check the following:

Have you checked the dimensions of the plate with the material you will be cutting? Especially the thickness - underestimating the thickness (z axis) can result in punching the bed
Are you Parts nested far enough apart?

Preflight checks before exporting NC Files - Continued

Have you selected the right cutting tool for the job - cut diameter, cut depth, correct tool for required finish on the material, and for the features of the design (eg dogbone corners etc)
Does the actual tool match the tool selected in the library for the toolpaths?
Is the cut depth of each of the toolpaths consistent with the required depth? Are you sure your toolpath will not punch the bed?
Have you selected the feeds and speeds recommended for the tool and material you are cutting?

Preflight checks before exporting NC Files - Continued2

Have you set your toolpath to cut in the right number of passes? - Max pass Z ≤ tool diametre.
Have you have selected correct cut direction (conventional or climb/ raster or offset) and vector offset (inside outside or on the line)?
have you inserted the required depth, width, number of tabs and that the position of these is optimised?

Preflight checks before exporting NC Files - Continued3

* have you run an estimate cut duration and any tool changes to ensure you have enough time complete the job within you booking time.

Before exporting NC file have the Fabrication Lab Supervisor check your settings.

LINKS

Preflight checks - getting the Machine ready to cut

Is there a hot work permit in place?
Is there room in the extraction bag for your saw dust?
Check the required tool is is in the machine and is secure?
Has the tool been qualified?
Has the machine been homed?
Are the required Vacuum bed zones are turn on?
Is the material secure on the bed?
Have you loaded the right cutting file ( Preview File on the A2MC console)?

Tangential Knife Operations

anonymous@undisclosed.example.com (Anonymous) — Mon, 23 Jul 2018 14:27:27 +0000

Tangential Knife Operations

Step 1 - Swap out sacrificial boards

Swap the sacrificial MDF Board used with the spindle for the sacrificial Polystyrene Board used with the knife.

Step 2 - Remove AXYZ Spindle Unit

Move machine head to a position that is convenient for making changeover of the different tools.
remove the vacuum hose as safety collar.
With an allen Key loosen the 5x Hex Studs securing the Spindle mounting plate to the machine head mounting plate.
Disconnect control cables connecting spindle to the machine head by turning the aviation connector plug sleeve anticlockwise.
Support the weight of the spindle while simultaneously completely removing the hex studs.
Now place spindle unit safely to one side.

Step 3 - Install Multicam Tangential Knife Works

align the holes on the Knife Works mounting plate with the holes on the machine head mounting and insert the 4x hex studs and tighten.
1. Use the lowest holes available
2. Do not use the cross-threaded hole 2nd from the bottom on the left-hand side

Step 3 - Install Multicam Tangential Knife Works - Continued

When tightening bolts
1. support the knife with another pair of hands - or your gut hand
2. get the top left and bottom right screws 3/4 threaded.
3. make sure the knife plate is flat against the machine head mounting plate.
4. Thread the bottom left, then top right screws 3/4 threaded
5. Finger tighten all screws in the same order
6. Use the 3mm Allen Key to fully tighten.

Step 3 - Install Multicam Tangential Knife Works - Continued 2

Connect the control cable via the aviation plug.
Connect the air supply hose;
1. push the socket down
2. jam the hose in - the socket has teeth that will grip the hose.

Step 3 - Install Multicam Tangential Knife Works - Continued 3

Add 2 drops of machine oil to oil nipple (2 drops to be added every 2 hours of operation)
Execute function F58 - Changes A2MC from Spindle control to Tangential Knife control setting. At this point the machine will reboot
Allow the machine to home the knife on the X&Y axis

Step 4 - Fit Knife Blade

WARNING - KNIVES ARE EXTREMELY SHARP

Move Machine head to middle of table and place scrap foam on knife as guard whenever knife is not in use.

Extreme care should also be exercised when handling Knife blades as they are expensive and fragile and are likely to break if dropped.

Only remove them from their packaging over the sacrificial board

Step 4 - Fit Knife Blade - Continued

- Wear protective gloves whenever handling the knife. - Select specific knife blade appropriate for your cutting requirements. - The knife cutting length should be as close as possible to the thickness of material - Again, position Machine head over sacrificial board in a convenient position for installing the required knife blade. - Execute Function F42 to 90 deg to expose the knife retention grub screw and remove grub screw with 3mm Allen Key. - Insert Knife blade with into holder with keyway oriented to the grub screw hole. Screw in grub screw and tighten.

MAKE SURE THE KNIFE IS FITTED STRAIGHT The grub screw should only contact the flat area of the knife blade hilt

Step 5 - Set Knife Length

The machine head needs to be calibrated to the correct Z axis value so that the knife tip's highest point of travel is level with the upper surface of the sacrificial board. This requires the operator calibrate the z axis manually ( or by eye) while the knife is reticulating.

Now move Machine head over sacrificial board.

WARNING the next Step Starts the Knife

Step 5 - Set Knife Length - continued

- Execute Function F24 - Set Knife Length. This will start the knife's reticulating movement.

Using the Z axis jog buttons (and =/- buttons to adjust jog speed -fast, medium or slow) to lower the tip of the blade slightly into the sacrificial board.
When you have adjusted the Z axis to the correct depth the tip should be just under ( by the smallest fraction possible) under the surface of the sacrificial board at the highest point of travel.
When you are happy with the calibration of the Z axis select enter.
A2MC will now ask if you want to Set Knife? Perform a visual check of whether the knife is running parallel to the X axis. If the knife is aligned on the X axis Select no. If the Blade is not aligned select Yes and perform the Set Knife procedure.

Multicam Commissioning

anonymous@undisclosed.example.com (Anonymous) — Mon, 23 Jul 2018 14:27:27 +0000

Multicam Commissioning

Documents the installation and commissioning of the CNC.

PRE-INSTALLATION Discussion

WEDNESDAY 22 June Members of the program team (Peter, Phil Andrei & Mick) did some brainstorming to identify some of the key tasks, frameworks and challenges around getting our new CNC machine installed, commissioned and engaging members of the community to experiment and productively use this new plant.

As a leaping off point we tried to identify all the tasks that need to be consider/ completed before the edge can begin delivering the 12 inductions and Cubby house project we are committed to running before tHe end of the 2016 Calendar year.

Inductions are due to start (and are booked into the calendar - soon to be promoted) in Mid september. The Cubby house needs to start around the same time if cubbies are to be completed for xmas delivery. working back from these 2 milestones we were able to identify

a series of questions/ challenges and
tasks with rough deadlines

Hopefully this will provide the detail required to draft a project plan which may or may not be formatted using SLQ processes.

Questions - Challenges

What level of supervision do we need for this machine?
How are we going to manage competing supervision priorities especially considering the loss of the dedicated FLS position?
the aim is to increase our open lab hours to 5 days a week. Given the level of supervision required for the CNC is it feasible to extend this greater span of hours to the use of the CNC also?
What materials are we going to encourage the use of on the machine?
How much material are we going to go thru and what variety will we offer?
How are we going to receive, handle and store these materials?
How will we approach selling these materials, consumables (cutting tools)?
What are the various task required in the installation of the machine
Whats the comms plan to support this project

trello board for this - here https://trello.com/b/VdgYUIyv/cnc-commisioning-questions

Tasks

Staff Training

Appropriate Cad platform(s) ( Fusion 360? what else?)
Designing for CNC - all the trick and tips to make CNC effecient, tidy, professional
Machine Use
Work Flows

OH&S

Risk Assessment
Safe Work Instructions
Identify dimensions of competency Levels 1, 2, & 3
Draft Induction materials and instruments Levels 1, 2, & 3
Test run induction
procure/ install safety equipment ( sound protection, fire protection, breathing protection.)

Establish Workflows procedures

run a series of test projects (bulk shelving, arcade cabinet, test doll house battle).
see machines running in other contexts (Griffith, RMIT, the Trophy Place)

The official manual has no mention of:

Order of machine operations.
Bed calibration
tool change
tool calibration
interaction between enroute and machine

Building on Experience

Using our experience of commissioning the Laser as a guide we can project the type of use and level of booking we'll experience in the first 6 months.

Over the first 6 months we have programed 12 inductions each with 6 participants. Based on previous uptake we'd expect bookings to slowly grow to about 20 per month fortnight.

If we stick with 3x 2hr bookings a day x 3 days a week there are 9 sessions a week and 36 sessions / month

Commission Part Two

Since the meeting I have though of a few more things and it coalesced into three different sub projects in my mind. i gone dun a diagram.

i've left space in it for you guys to add to it. so let me know what you think

I've started trello boards to track progress in each of these sections, with the aim of feeding it back in here once we are done.

Machine Safety

anonymous@undisclosed.example.com (Anonymous) — Mon, 23 Jul 2018 14:27:27 +0000

Machine Safety

When machine is running, keep clear of any rotating or moving parts eg. the cutting bit, spindle moving gantry and head parts.
Do not lean on machine whilst in operation.
Parts of the machine , particularly cutting bits, will get hot so you may need gloves when handling/ or changing tooling.
Maintain a clean workspace-check that the gantry and rails for tooling/materials left behind.
Clean up as you work. The machine does the messy work for you to clean up!
Use the right tool for the job. Different tooling pieces have a specific purpose and material.

Safety - Emergency Stop

The CNC is fitted with an emergency stop.

This can be activated to bring the machine to an immediate stop in an emergency.

Note -if the machine is turned OFF mid operation, wait 1 minute to turn ON. After activating emergency stop, needs to be homed.

Safety - Operator Hazards

The spindle

The spindle spins at up to 18,000 rpm - capable of cutting at over 10 metres/minute (m/m)
- through metal
- (or flesh)
The bit takes at least 30 seconds to come to a complete stop.
- Every time.
- Even if you touch it.
The bit can fracture, break or shatter.
- A bit rotating 18,000 RPM will fly out about 50 km/hr
  - at your eyeball

The Gantry and Machine Head

The gantry can move at over 10 meters/min and weighs over 100 KG.

It can hit with enough force to knock a person over, or trap and mangle a limb.

Safety - Damage to Machine

The vacuum bed is soft aluminium. If it is damaged the machine is unusable.
Drill bits are brittle, and will shatter or crack if dropped on concrete.
The router will cut through metal clamps and screws

Machining Small Objects

anonymous@undisclosed.example.com (Anonymous) — Thu, 20 Sep 2018 16:54:15 +0000

Machining Small Objects

When machining blanks that are not large enough to use vacuum, clamps should be used. There is a set of clamps. The set consists of clamping bars, adjustable height blocks, T slot nuts, studs and nuts. (17mm) If the part is to be completely cut out, a spoil board is needed. The spoil board’s size need to be larger than the footprint of the blank, and small enough to work within the T slot rails. Place the blank onto the small spoil board and position at least three clamps. There are breaks in the T slots on the machine bed for the slot nuts to be inserted and slid into position.

Defining the new Zero height.

A change in spoil board requires a recalibration of the zero height. Use FUNCTION 28 to set the height of the spoil board. MAKE SURE THE TOOL HAS BEEN QUALIFIED BEFORE PERFROMING A FUNCTION 28. Bring the tool down to touch off the height of the spoil board.

Supervisor Preflight Check

Just like the supervision of the Laser Cutter there are a number of critical factors that a Fab Lab Supervisor needs to satisfy for themselves before Green Lighting a job. it is not a question of skill or experience (newbie or an experienced machinist) - Only a recognised Fabrication Lab Supervisors have the delegated authority to supervise the use of Edge Fabrication Lab tools and approve the safety of each and every job.

As such the Supervisor on duty must satisfy for themselves

Safety

The area is clean and safe to operate the machine in
Everyone in the area is wearing the correct PPE
Everyone in the area is has received a safety brief.
The Machine is maintained and safe to use

Preflight Check - Machine physically ready to use

An appropriate cutting tool has been selected for the job
The cutting tool is correctly fitted on the machine
The material is appropriate to be cut on this machine and is secure on the bed
There is no tools clamps or fixings in the path of the tool or that will obstruct the movement of the gantry.

Preflight Check - BEFORE EXPORTING JOB AS NUMERICAL CODE - Check Job is Programmed Correctly//

Feeds and speeds are appropriate for the material being machined and the cutting tool being used.
Depth settings hare appropriate for the thickness of the material.
Maximum Depth of cut has been verified.
Correct Plate dimensions have been verified.
Program Simulation has been run to verify correct programming of job.

Preflight Check - Last checks before go

Verify that correct version of the NC file has been sent to machine.
Ensure machine has been homed.
Ensure correct tool has been verified.

During the Job

Ensure participant is actively observing progress of job.
Ensure participant is watching for small parts being sucked up by/ stuck in the vacuum extractor.
Ensure participant is watching that vacuum hose and extractor/ guard assembly does not foul with material.
Ensure only one person inside yellow line when machine is operating.
Ensure that operators are verifying that the spindle has completely stopped before approaching machine (encourage use of Point & Shout technique).

Tool Change

Changing of tool is an operation only to be carried out by a Level 2 certified user or the Fabrication Lab Supervisor.

Move router to over bed (this is so if the bit drops it doesn't hit the ground)
Pair the right sized collet for the cutting Tool you have selected
Blow collet out clean with compressed air
Blow Collet nut out clean with compressed air and inspect (clean collet nut with steel wool if required).
Inspect Clamping nut surfaces on the Spindle (clean with steel wool if required and blow out clean with compressed air)
Fit collet in Collet nut with an audible click

Tool Change Continued

Hand tighten collet nut (and collet) onto spindle - take care not to cross thread
Place Bit into clamping hole of collet and hand tighten until collet begins to grip bit.
Adjust bit so that approx 5mm of bit shank is exposed below collet (ensuring swarf will clear flutes of bit without feeding up into collet.
Tighten Collet nut using Collet nut Spanner and Spindle Spanner. Note not too tight.

To Tighten - Squeeze the Tools together.

On CNC Control Console go to TAB 6 and select appropriate tool for the job

Tangential Knife Operations

Step 1 - Swap out sacrificial boards

Swap the sacrificial MDF Board used with the spindle for the sacrificial Polystyrene Board used with the knife.

Step 2 - Remove AXYZ Spindle Unit

Move machine head to a position that is convenient for making changeover of the different tools.
remove the vacuum hose as safety collar.
With an allen Key loosen the 5x Hex Studs securing the Spindle mounting plate to the machine head mounting plate.
Disconnect control cables connecting spindle to the machine head by turning the aviation connector plug sleeve anticlockwise.
Support the weight of the spindle while simultaneously completely removing the hex studs.
Now place spindle unit safely to one side.

Step 3 - Install Multicam Tangential Knife Works

align the holes on the Knife Works mounting plate with the holes on the machine head mounting and insert the 4x hex studs and tighten.
1. Use the lowest holes available
2. Do not use the cross-threaded hole 2nd from the bottom on the left-hand side

Step 3 - Install Multicam Tangential Knife Works - Continued

When tightening bolts
1. support the knife with another pair of hands - or your gut hand
2. get the top left and bottom right screws 3/4 threaded.
3. make sure the knife plate is flat against the machine head mounting plate.
4. Thread the bottom left, then top right screws 3/4 threaded
5. Finger tighten all screws in the same order
6. Use the 3mm Allen Key to fully tighten.

Step 3 - Install Multicam Tangential Knife Works - Continued 2

Connect the control cable via the aviation plug.
Connect the air supply hose;
1. push the socket down
2. jam the hose in - the socket has teeth that will grip the hose.

Step 3 - Install Multicam Tangential Knife Works - Continued 3

Add 2 drops of machine oil to oil nipple (2 drops to be added every 2 hours of operation)
Execute function F58 - Changes A2MC from Spindle control to Tangential Knife control setting. At this point the machine will reboot
Allow the machine to home the knife on the X&Y axis

Step 4 - Fit Knife Blade

WARNING - KNIVES ARE EXTREMELY SHARP

Move Machine head to middle of table and place scrap foam on knife as guard whenever knife is not in use.

Extreme care should also be exercised when handling Knife blades as they are expensive and fragile and are likely to break if dropped.

Only remove them from their packaging over the sacrificial board

Step 4 - Fit Knife Blade - Continued

MAKE SURE THE KNIFE IS FITTED STRAIGHT The grub screw should only contact the flat area of the knife blade hilt

Step 5 - Set Knife Length

Now move Machine head over sacrificial board.

WARNING the next Step Starts the Knife

Step 5 - Set Knife Length - continued

- Execute Function F24 - Set Knife Length. This will start the knife's reticulating movement.

Using the Z axis jog buttons (and =/- buttons to adjust jog speed -fast, medium or slow) to lower the tip of the blade slightly into the sacrificial board.
When you have adjusted the Z axis to the correct depth the tip should be just under ( by the smallest fraction possible) under the surface of the sacrificial board at the highest point of travel.
When you are happy with the calibration of the Z axis select enter.
A2MC will now ask if you want to Set Knife? Perform a visual check of whether the knife is running parallel to the X axis. If the knife is aligned on the X axis Select no. If the Blade is not aligned select Yes and perform the Set Knife procedure.

Preflight checks - Vcarve

Before Exporting the NC file for your cutting program from VCarve check the following:

Have you checked the dimensions of the plate with the material you will be cutting? Especially the thickness - underestimating the thickness (z axis) can result in punching the bed
Are you Parts nested far enough apart?

Preflight checks before exporting NC Files - Continued

Have you selected the right cutting tool for the job - cut diameter, cut depth, correct tool for required finish on the material, and for the features of the design (eg dogbone corners etc)
Does the actual tool match the tool selected in the library for the toolpaths?
Is the cut depth of each of the toolpaths consistent with the required depth? Are you sure your toolpath will not punch the bed?
Have you selected the feeds and speeds recommended for the tool and material you are cutting?

Preflight checks before exporting NC Files - Continued2

Have you set your toolpath to cut in the right number of passes? - Max pass Z ≤ tool diametre.
Have you have selected correct cut direction (conventional or climb/ raster or offset) and vector offset (inside outside or on the line)?
have you inserted the required depth, width, number of tabs and that the position of these is optimised?

Preflight checks before exporting NC Files - Continued3

* have you run an estimate cut duration and any tool changes to ensure you have enough time complete the job within you booking time.

Before exporting NC file have the Fabrication Lab Supervisor check your settings.

Noise

From the Safe Work Australia ¹⁾ documentation

The national standard for exposure to noise in the occupational environment is an average daily exposure level of 85 decibels. This is consistent with overwhelming scientific evidence which indicates that exposure levels above 85 decibels represent an unacceptable risk to the hearing of those exposed.

It also states:

The levels specified in the national standard are the maximum acceptable exposure levels for noise in the workplace. However, over long periods, repeated noise exposure at between 75 and 85 decibels may be a small risk to some people. With progressively increasing levels, the risk becomes greater. Workplace noise levels lower than 85 decibels are, therefore, desirable, if practicable.

Multicam Noise Levels

According to the specs ²⁾ the base level of the extractor is 82 dbA. We can assume that the router itself is going to vary depending on material between 70 - 105 dbA. This means the constant level will be at least 82 dbA, rising to 105 dbA.

If we assume this is measured at one metre, we are looking at a level of approx 75 - 95 dbA in the kitchen. Consulting our table, this means that without sound treatment, hearing damage would occur within 1 hour if sitting in the kitchen.

Multicam_Commisioning

Research

After discussion with Albert Maberley - technician at RMIT advanced manufacturing Institute. All machines on their shop floor have enclosed beds with externally vented extraction to take care of small particle dust (10 micron or smaller). These were his comments.

Noise - reccommended personel wear ear protection at all times, and do a noise dosimeter servey.
Public Access - No public access to machine shop floor
Dust - wearing dust masks during machine operation. External venting of small particulates advised.
expect severe head crashes to occur regularly - at least 1/year with 5 hours use/week per operator- plan for operator safety with shielding
expect bit breakage to occur = at least monthly with 5/hours week per operator.
pre-flight cut simulation is essential to catching errors in programming before cutting
machine bed will need re-surfacing or replacement.

Router Tooling, Feed Rates and Cutting Speeds

anonymous@undisclosed.example.com (Anonymous) — Mon, 23 Jul 2018 14:27:26 +0000

Router Tooling, Feed Rates and Cutting Speeds

Tool Geometry

You always want to use the right tool for the job.

Different tool geometries produce different effects and results with the range of materials that can be cut on this machine.

Tool Geometry
Straight Flute	Will not lift material out of cut.
Spiral Flute	Spiral Flute lifts swarf or pushes it towards cut. depending on geometry
Flute Geometry
Single Flute	Single Flute cutters only have one cutting edge. These are good for faster feed rates in softer materials.
Double Flute	Double Flute cutter have cutting surfaces and are good for cutting harder materials at slower feed rates.
Upcut Spiral	The geometry of an upcut spiral draws swarf up and out the top surface providing the best finish on the down side of the material
Downcut Spiral	The geometry of an downcut spiral draws swarf down and out the bottom surface providing the best finish on the upper side of the material.
Compression Cutters	Compression Cutter have both upward and downward spiral geometry that forces swarf both upward and down and produces a clean finish on both upper and under sides of the materials and is particularly useful in applications with laminated materials.
O Flute	Identified by the Half moon shape, OFlute cutters have a single flute that ejects swarf effeciently. As such they are suited to cutting timbers and plastics (softer materials ) at high speeds.

Suggested Feed Rates - Soft woods/Plywood

Tool Type	Tool Diameter	Spindle Speed	Feed Rate	Plunge Rate	Direction
Single Spiral	3.175mm	16,000rpm	2,000mm/min	1,000mm/min	Conventional
Single Spiral	6.35mm	16,000rpm	4,800mm/min	3,000mm/min	Conventional
Double Compound Spiral	9.5mm	12,000rpm	11,280mm/min	9,000mm/min	Conventional
Double Compound Spiral	10mm	12,000rpm	11,280mm/min	7,000mm/min	Conventional
Triple Compound Spiral	10mm	12,000rpm	16,920/min	12,000mm/min	Conventional
Triple Compound Spiral	12mm	8,000rpm	13,320/min	11,000mm/min	Conventional

When you are cutting your job

Are you and (everybody in the room) wearing your PPE?
Are you and (everybody in the room) standing behind the yellow safety line?
Are you alert and ready to hit the emergency stop if required?
Are you ready to hit the pause button to clear debris?
