General Mach Discussion / The Results :

A little while back I wanted to use a rotary table as a "Poor Man's Turret CNC"
With the help of Hood this is the result. Also the tool wear offset has been changed so that
you make the part BIGGER by + tool wear, SMALLER by - tool wear (same as Okuma, Hass, etc.

General Mach Discussion / Mach3 Turn

« on: December 01, 2012, 07:12:29 PM »

I am hoping for a "poor mans" Turret.
Let me give an example :
As in mill we would home X, Z and A (Home The Rotary Table (A)  At 0)
We would then write.
G18 G20 G40 G80 G95 (Normal Heading Etc.)
A30 (Tool 1 Position By Advancing The Table To 30 Deg.)
T101 (Get Tool Offset)
G00 X 1.5 Z.1
G01 Z -.75 F.02
G00 X 1.75
Z.1
A90 (Tool Position 2 By Advancing The Table To 90 Deg.)
T202 ( Get Tool Offset)
We keep the rotary table going in the same direction so we have no lash.
We could have a tool every 60 Degrees.
I need to know how to add a DRO window for "A" on the turn screen.
Is this possible ?
Thank You very much,
JR
