I am new at Haas and I have a few questions.

The programmer from Haas is supposed to come around next week.

How do you edit programs properly with zero offset ( I can approach the tool with the index arm.)

How do you use cycles G71 and G72 when rough facing/ finishing, longitudinal roughing and finishing - diameters from 14-9; 45 long?
Are there any undercut cycles?

Could anybody write me a short program with G51 and G54?

Kind regards
Alex
