| 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.

| | |
| 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<nowiki><br></nowiki>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.

| 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
