Problems with trimmed toolpath

[ICT_Outkast]

Using V9 SP1 and we are having trouble with trimming toolpath. It trims the path just fine, but it throws in some strange Z moves....X and Y will position to a point, rapid down in Z then rapid back up, without cutting anything, then position for the next actual cut...(hope this makes sense)...Like I said, it trims the actual toolpath just fine, but it sort of freaks out the operator when it comes down and doesn't actually machine anything. Anyone have any ideas?

 

Thanks,

It was before even in ver 8 and 7.

So, there's no fix that you know of?

Trim is a simple filter !

It cuts your toolpath by criterium and has no logic.

If you cut your toolpath in XY plane that doesn`t means that you cannot cut in XZ or else .

So if it cut your pathes in xy it will not cut jumps between them !

Gotcha....thanks....

 

sorry...after reading my reply I sounded like a xxxx....wasn't intended that way....

 

Thanks for the reply.

I have a couple of questions:

 

1) Is this a surface toolpath you are trimming? If so why not use tool containment boundaries? The only time I've ever really used trim with surface toolpaths was in v7 and v8, now in v9 you can use as many tool containment boundaries as you like and they can be nested.

 

2) If this is one of the wireframe toolpaths are you trying to trim to the edge of the path you made? If so extend your toolpath beyond the extents you want it trimmed to then it will trim just fine without those z moves.

 

 

You will get those z moves whenever you are trimming to the very end of your toolpath. If you offset your trim curve to the inside .0001" they will go away.

Jerry , it s OK !

 

I love trim and use it a loteven with surfaces .

 

One example :

I have a lot of parts that have 120 radial angle slots ,rotated 3 degrees around center,that I do surface parallel .

The part I fix to the table with clamps change .

Well , being a lazy man I do one toolpath,transorm-> rotate it by 3 degrees needed times and copy the toolpath .

Then I trim toolpath twice , one for one clamps position ,second for the second one.

I made a typical operation library and all my process for a new part writing takes me 10 minutes, to change geometry and make a regen !

 

I love Mastercam !

Thanks Ya'll.....I think I have it figured out....seems to be working this time anyway....Appreciate all the good help

to Roger Peters0n,are you sure tool containment boundaries can be nested in ver 9?
