I never use that cycle mostly because you have no control over things like
approach and depart.
It is so easy to make your own toolpath for that that you are not saving any
time.
If you are repeating the same thing more that once just make it in
incremental in a separate program and call it with M99 just like drilling..

Looks like not many have experienced the POWER of Heidenhain?
This old SOB is way ahead of Fanuc/Semens/GE/DynaPath IMO.
Don't know what the new ones are like, but this control is a CNC
machinist's dream.
6 power feed buttons- no switching the one selector axis & increment
button. The feed rate(variable knob) is constantly displaced on the
screen, even when its just sitting there. Oh no feed hold button for
automatic run! Turn the knob down & its in feed hold. The spindle
orientation -in degrees- is also always displayed on the screen. Even
power on - start-up is the fastest I've ever seen! 30sec's I'm running
the same program as the day before. With glass scales on the machine
tool, this baby is accurate.
Take away Hurco's DXF & Heidie's got it beat. Even some 3D stuff its
better than Hurc-n-ater.
Its pre defined cycles, like 213 are kinda quirky, but they do work
with very minimal info input.(me like)
FYI I put in a small CREM to do a top edge & it leads in/out close to
the part. But the 1/2" tool leads in/out about 1" away? Same program-
just different tool.

Does anyone know if there is a parameter setting for CYCLE 213 (stud
finishing) to reduce the lead-in distance (away from the stud) ? The
tool enters about an 1" away & will hit other contours close by.
I've looked in the manuals, but not much besides an explanation saying
the TNC426 automatically pre positions the tool.
This cycle must have been an update in software. Its not even listed
in the main manual.

Thx
