CNC Lathe Notes

Centroid controller

G-code with some extra M-codes

lathe motor is 10-HP, but, with VFD speed control %age of top speed corresponds to roughly the mount of HP availabe.

Uses Tri-Cool for coolant

Chk oil level on back, way oil

Turn on

Set home: Green button at lower right of controller will cause it to run through its homing procedure.

The tailstock will trip the furthest Z-limit switch, so move tailstock towards chuck. If it is not appearing to move switch from ‘Inc’ to ‘Cont.

MPG: Mean Pulse Generator

Part Design Considerations:

• Inside corners should have radii greater than that of the tool insert tip.
• Outside corners should be set to 0.005-0.010” radii to avoid burrs.
• Stock to leave for finish passes: 0.015” axial & 0.030” radial
• Can cut 0.1” off of radius with Aluminum

Define tools in HSMWorks<br>Define Tool Positions & Angles<br>Define Tool Feeds & Speeds

Parting in hard alloys should be 300SFM for carbide cutters

Parting defaults to 0.040”/rev., which leads to DESTRUCTION! Better to set at 0.0035”/rev.

Make sure that your tools have different numbers in the tool library for a single job

Inserts with a negative rake are mounted at an angle on the toolholder, so cannot cut away from the chuck as the rake is actually negative in that direction.

Set max spindle speed when changing gears and ranges. This is a global var?

Post-processing: Use FANUC

G53:  Retract<br>G54:  Work Offset

Keep in mind that G53 & G54 go to coords (0,0) which will be the face of the stock.

Tool changes are done explicitly by:

• Rapid Traverse  -  G53, G54, etc.
• Tool Offset
  • Home machine
  • Set 0s on stock
  • The set tool offsets

In graph mode we can get range to see only those moves due to those lines of code.

VS-Codes is good for editing G=code. Use G-code add-in

Use locknut on toolholder to avoid changing height when handling toolholder.

F1/Set-up

F2/Tools

Offset Library

Tool: may set to 0, or set offset to a Var

MPG: Can turn off to avoid changing values if you accidentally bump into the hand wheels during operation

F2/Measure

Sets the offset

Set Z-Ref: 2” when using indicator

Move manually to where you expect (0,0) to be and look at the numbers on the screen as a check.

Run Menu

Set part count to 1

Re-set spindle speed and coolant back to Auto CTRL

For the big chuck, the max speed is 700RPM

For the Medium chuck, the max speed is 900RPM

For the collet closer, the max speed is 2-2,400RPM
