I am reading the manual for G-code programming a TM10 Lathe W/Max Control.

G33 looks simple.

GZK is all that is asked for...........G33Z-.8K13.0

I used Mastercam x8 to long hand to program.

Ended up with this:

G0 G53 X15.6693 Z24.9606 M5
G0 T0404
G97 S200 M03
G0 G54 X.3919 Z.2174
X.4424
G33 Z-.8 K13.0
G0 X.3919
Z.2141
X.4541
G33 Z-.8 K13.0
G0 X.3919
Z.2116
X.4632
G33 Z-.8 K13.0
G0 X.3919
Z.2094
X.471
G33 Z-.8 K13.0
G0 X.3919
Z.2075
X.4779
G33 Z-.8 K13.0

It faults on the G33 block.

The manual that I am using is very simple. What am I missing?

Thanks for your help.

for a simple thread cycle usually needs X end point Z end point and F federate rated to pitch.
G33 X<x> Z<z> F<f>
for compound thread cycle needs extra parameters like Q times R return point and K thread height.
I think you missing federate
For example spindle 100 rpm and thread pitch 1mm F=100
100 rpm and thread pitch 1.25mm F=125
200 rpm and thread pitch 1.25mm F=250 etc.

Thanks.

I tried F.0769 at the control on one bock to see if it would pass that block and go the next with the K in it and fault out.............It faulted even with the F.0769

I noticed that an E can be used as well. I have not tried that yet. Taking tomorrow off so I will not be back to try any other things until Friday.

Thanks for the input.

This may be of some help with using G33

I think E can be used for threads/inch.
Try G33 X<x> Z<z> E<threads/inch>
