transform toolpaths in lathe

[rcktray]

I'm trying to transform an id groove toolpath using translate toolpath. When I set my transform parameters for the 3 other id grooves the tool rapids thru the part at the beginning and end of the transformed toolpaths, even having a reference point in my source toolpath for the rapid start position. If I use the copy source operations it will go to the correct rapid position at the start of the transformed opp but repeats the original groove opp and after it is done it rapids thru the part to the machine home position. Is there a way to set a reference rapid point in the transform parameter page?

 

Thanks for the help

Strange as it sounds, close mastercam and reopen. Regen everything. For whatever reason, I have seen it lose track of the part/stock and make the colliding rapids in and out. Not guaranteed, but something I have found works on occasion.

 

also, Go into your transform and check disable posting in source op.

bad news - toolpath transform doesn't work well for this....

good news - grooving in X4 supports multiple chains

....reason being the toolpath transform doesn't update stock the way true lathe paths do....

i never get good result with toolpath transform on lathe

 

 

as Criss said , restart mastercam , it's the first thing i do when i get some weird things

Now that I think of it, the last time I transformed in lathe was the entire part, not just a toolpath or two. I'd think the stock updating/retract/clearence would cause all sorts of problems for one path.

Thanks for all your input. I have also done the restart on occasion and had some success but not this time. Come on X4

I just programmed up a washer type part with 4 ops and a cutoff op. I transformed it 3 more times. Backplot shows the tool crashing through the part, but verify looks good, and the output gcode looks good in X3/MU1.

 

Using X4 the backplot is still crashing through the part, verify is a complete disaster, but the output gcode looks good to me.
