Hey guys I have a quick question. I am machining a rectangular part. Its basically 12"x10". The external profile that I need to cut basically moves up in z about .14" then curves to the right in X+ about .1" then up in z about .2" and finally stops at the top of the part.

So I am having trouble figuring out which tool path to use. I have tried a few and I am just not getting the result I am looking for. I want it to go around the entire premeter of the part at several different z heights. Let me know of any suggestions. I am trying to utualize a 3/16 bull mill.

This is an example of what it looks like.

This is the profile, its the portion on the right.

Also trying to avoid using a form tool.

top select analyze or F4

select the line

change the z on the end you want to raze and leave the other one the same.

do all the lines changing the z's

Esc key

select contour

post the code.

I don't think thats the solution. I need to start at the top of the part and work my way down in z following the outside contour of the part. So like 10 steps down in z with about a 10 percent stopover.

Change your "Contour Type" from 2D_Contour to 3D_Contour, your chain that you selected should be the top chain, top of stock = zero(incremental), depth = (say -0.5), inremental
set your multipasses & depth cuts to your needs

You probably actually wanted something like this:

what type of material, is there a previous rough, version of mastercam and mill level you have?

[NW_Phil]

oh and you using clamps on the inside? or a bolt pattern to hold it down? oh ya and max rpm and feedrate of machine im board with the bath tub im making out of 316 ill toss something together for ya

personaly id use waterline and contain to the outside depths of .005 and add cuts max profile step over of .005. could scream if you got a decent spindle and look ahead.
