basic programming TL2 lathe

[lostpinky]

I took over here at a new job and have never programmed a lathe. I have a basic programming question about the lathe. The guy before me set up his programs so that all you do is set the Z tool offset for tool #1 and all the other tools that follow seem to be at the correct depth. Do you know how he has done this? If I change a tool, say a drill, and set the Z off the part face, the drill will be at the wrong depth. I have copied a tool change below:

G2 X.4027 Z-.875 R.0144
G1 X.5646
G3 X.5938 Z-.881 R.0206
G1 X.6866 Z-.9274
X.828 Z-.8567

G29 X6. Z6. M05

(TOOL - 3 OFFSET - 3)

This should be posted in the Haas Lathes Forum.

Check setting 64, it should be off. If all of the tools are set from a common point in Z, then your work offset is the distance from that point to the face of the part. So, if you have touched all tools to the face of the chuck, then your G54 would equal the distance from the face of the chuck to the end of the part (positive value).

Your tool calls in the NC example are correct.

sorry, thought the lathe and mills were both covered in the same place
