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.

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

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).

LINKS

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

LINKS

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.

Other Knife Operations

Manual Tip-Off

This Function is used for tool tip off if the tool is physically bigger the the touch disc mounted on the gantry or when planning the waste board.

Change the tool using Tab 6 → Change → Select Tool eg 45mm Surface planer (Tool 10)
Insert the 45mm Surface Planer and press ok.
Move the spindle roughly 300mm x 300mm in from the home position
Key in F24 to select Manual Tip-off
Drive the head physically down to touch the wasteboard. use the +- button to cycle through the speed options (Fast, Medium, Slow, Step). Once touched the board press ok.

LINKS

Planeing the Wasteboard

1) Position the wasteboard hard into the corner and location blocks

2) Turn on the vacuum pump!

3) Remove location blocks!!!`

For a new board both sides need to be dressed to remove wax coating and level the board. 1.5 to 2 months under heavy use. 1mm deep initially on first side on a fresh board .5mm deep on second side on a fresh board From this point the board should need not flipped until a new board is used. .2mm deep there after on the same side

Planning the Wasteboard

4) Key in F28 on A2MC Console

Set waste board No

Wasteboard must be set AFTER the planing table or machine bed damage may result!

Plane table yes
Tool Diameter 45
Overlap 50%
Length (X Axis) 2420mm
Width (Y Axis) 1230mm
Z depth .5 mm
Feed rate 12000mm
Spindle RPM 10000
Set origin NO
Plane table Yes

Set the Wasteboard

When planing is complete replace location blocks.

Now you need to set the waste board (ie zero the Z Axis)

5) Key in F28 on A2MC Console

Set waste board Yes

Jog tool down to complete a manual tip off (as per manual tip off) and press OK when you are have just touched.
