Stock recognition milling X3

[gary adams]

Hi all

In the current newsletter under multiaxis toolpaths, there is a description of a stock recognition function for milling.It explains it as eliminating wastefull air cutting. I have not found anything like this in X3, my mastercam supplier says it relates to turning only, but that is not the way I read it as it refers to cutter diameters and a milling operation.Anyone who can shed light on this I would be very gratefull.

regards

Gary its called rest machining in HST.

You can use a STL file as stock or a previous toolpath.

You have mail

Gary, DavidB might have answered this in e-mail, but if you're using the Advanced Multi-axis toolpaths:

 

Under parameters, click the Misc Tab

Switch to advanced interface

Under roughing, there's a Stock defnition option

It'll then give you some options to choose from. I usually have my stock modeled which I then save out as an STL file, and I nagivate to this and use it with stock definition. It will perform cutting moves within the defined stock, and then you can use Link parameters, extend/trim etc. to control how the tool moves between passes

if you are using solids you may be able to use the 2d HST tool path called 'core mill'. requires two chains. basically the stock boundary and the solid edge chain. there is a video showing it somewhere in the what's new documentation in X3. this is not multiax though. I wonder if you could then utilize the 3 to 5 axis convert?

Thanks all problem solved

[DavidB]

What did you end up doing Gary?

The problem solved is the one I had relating to the current newsletter, refering to stock recognition, which I now know (thanks to Tyler) relates to multiaxis toolpaths.The elimination of air cutting from a variety of stock shapes seems to have a variety of solutions.I have not found a one size fit all solution. Your solution of rest milling from STL file is good but limited to plunge capable cutters, having said that it is often the best way.

Not true actually HS toolpaths dont plunge at all. They helical ramp or ramp to cut depth.

Sorry bad chioce of machine shop english. What I wish it did however was apply the z down outside the stock boundry, in a face mill type manner, alowing a face mill to be used giving higher metal removal rates.

HST Core Roughing will do this but it won't use a stock model. Using a containment boundary I can usually get what I want.

 

It would be REALLY nice to be able to pick a solid for rest mill instead of having to use an STL.

Area Clear or Core Rough with a 2" button cutter followed by a Rest Rough with a 1" button cutter. We do it almost every day, here. It can be done!
