Say we were to cut this 8" slot w/a .25 ball endmill ?
.02" per pass.
.5" deep
That would take a CAM to generate that ... right ?

HIYA RUSS not neccesarily a SUB program to step over or down  each pass can do a LOT of work in place of a CAM.  The real question is this slot really a pocket instead of a slot. and how deep is it and how wide is it.

You really do need to do it with a ball end mill as a flat nose mill will scallop the surface cutting the arcs.

Yes, I was assuming a pocket, same width as the ball endmill.
I was also seeing the SUB cutting a lot of air by just shifting the final profile for each pass (.05" in the top example).
I was trying to figure how to do it as in the bottom illustration .... 10 passes without wasting time cutting air.

I did do it in SCam , each pass individually but it was painful.

Thanks again TP,
Russ

Funny thing about CNC and time. As long as "I" am not turning the handles and can be doing something else I don't seem to miss the extra cutting air time much.

BUT if it is a production thingy time is money

YA did a good job here Russ Keep up the hard work bud.

Thanks Terry,
I appreciate the encouragement.

Someday, I might just be able to draw stuff quicker than I could whittle it out of oak with my penknife.

sorry guys  thanks for the ideas. still not right. what I need is a G or M code for the Y axis that will run indepently  of Z but at the same time
Y will do nothing more than run from zero to 8 inches and stop while z is making its cut
is there a code that can be written that will run y from 0 to 8 while it is also running a z code

Thanks again for the help

OK, I will let BR549 take lead on this discussion.
It sometimes confuses teh person asking for help if 2 try to help at teh same time asking different questions .... Apologies if I've confused things.
