Forcing a start point

[TERRYH]

I am doing a surface rough pocket program to rough a part, the tool wants to start farther away from the part than I want it to and on our smaller machines this is an issue because of travel limitations. I am trying to force a starting point so it stays closer to the part and cannot get it to work properly. I have a point created and have selected everything I can find about a start point and it will not work. any suggestions? And I am using MCX6 MU3

How about a containment boundary.

how about editing the point in the operations manager?

right click on the operation, at bottom of pop-up :"toolpath editor"

[mkd]

^^it's a non associative change, so make sure everything else in the 'path are perfect first. otherwise you'll have to keep editing the point after every change

Had a containment boundary. Unless I make it large enough for the tool to go outside the part and stock size and try to make it stay inside the boundary.

In the chain manager for the operation make sure the point is first in the list of chains.

Are you telling it to plunge outside containment. It seems that it will plunge 1.50 times the diameter away from outside of the containment boundary.

[TERRYH]

Yes It is set to plunge outside the containment boundary. I was taught to create the boundary to the size of my stock block to make sure we cut it all, and so it don't rapid down on any stock. Not sure if that's how everyone else does it or not. And I played with the settings in the Entry-ramp tab if that's where you are talking about the 1.5 times the Dia. outside the boundary.

Terry did you start out using the start point?

If you added it to the toolpath later it dose not always work.

Try recreating the toolpath from scratch and make sure you turn on the start point from the very beginning.

OK will try that I think I did it that way once but not sure because it is a surface rough pocket program I didn't realize it made a difference if it was selected in the OP MGR, but will give it a try.

Surface Rough who doing what? Get off of that old school way of doing toolpaths and look to the new Highspeed toolpaths. Talk to your dealer and give them a try please.

LOL I have been trying but or company don't want to seem to get off the money to train us on the new stuff MCX can do, We are using some of it that one of our guys was trained on back to X2.
