Newbie- trying to use live tooling on z axes

[firekoe]

i am trying to put 3 holes on a .750 BHD .25 deep with live tooling in a yama seiki lathe with a oi-tc control and was wondering if anyone could give me an Ex. of how to do this

It will look something like this.

T1010
M23
G97S1200
M8
G0X3. Z1. C0. M13
Z-1.
G81G98X1.5R.1F13.
C90.
C180.
C270.
G80.
G0X8.Z4.

M28? Where? anyway.... check your manual for compatible.

According to the 0iT-C manual, there is no G81. Use G83 for face drilling, G87 for OD drilling. Also, R is an incremental distance to rapid before starting to feed.

This example is not for a Yama Seiki, but should be close:

T1010
M?? (ENGAGE C-AXIS ???)
G28 H0 (ZERO RETURN C)
G50 C0 (SET ZERO POSITION)
G00 G54 G97 X0.75 Z0.1 S3000 M33 (START LIVE SPINDLE)
M08
G83 G98 Z-0.25 R0 F12.
C120.
C240.
G80 Z1.0 M09
X8. Z4. M35 (STOP LIVE SPINDLE)
M01

Incidently, return point level (G98/G99) is not for G-code system A where the tool always returns to the initial level. G98 is for feed/min in system A.
