I am using mastercam 2021. There is no unified toolpath in this version. So mentioning your first finishing strategy, what tool path could i use instead of unified automatic option in my version?
That's a bit tricky :) One of the reason I designed Unified was to give easy access to the Geodesic engine in the ModuleWorks toolpaths. This is using one of those toolpaths, but there is a "back door" that was put into Mastercam a few years before Unified came out :) What you'll want to do is use the Parallel toolpath with all relevant features selected manually (like, in my automatic example, you'd choose the upper and lower curves, as well as the curves at the base of the two "ears"), then, expand "cut parameters" go to "advanced options for surface quality" page, then, switch from Approximate to Exact. That should give you a similar toolpath.
I am using rotary table on haas vf 5. Recently i programmed a screw with rotary advance toolpath. I am selecting generic haas 4x mill as post processor. The mastercam verification was okay till end. But when i generated code there is unexpected reduction in feed while A axis synchronization. In machine that is terribly killing my time. I hope i am making my point clear to you. Is there any solution for me. Please help me.
Hello! Yeah, you want to post out moves like that in Inverse Time (G93 www.haascnc.com/service/codes-settings.type=gcode.machine=mill.value=G93.html), or, preferably, if your machine has it you'll need to use TCPC (G234 www.haascnc.com/service/codes-settings.type=gcode.machine=mill.value=G234.html). What's happening to you is that it's putting your desired feedrate (say, F100), however, the control is reading that and it's converting that into Degrees Per Minute, so it's rotating at 100°/min, which means each revolution of the screw will take ~3.6 MINUTES, which is probably about 20 times slower than you want to run! You may need to edit your post to enable that functionality, and possibly talk to your Haas dealer if that doesn't have it. If neither is available, and you're cutting at a constant speed, you can enable degrees per minute output, but be careful, because every line will need a feedrate line and horizontal moves (that don't move the A axis) may come out wickedly fast. It's hard to get the post dialed in like that if you can't run TCP or Inverse. You often have to change your cutting strategy to just do spirals or arcs in the rotary.
I'm trying to foster an atmosphere of learning here for everyone, so please change your comment to specifics about how you would improve the processes/ideas presented here? I program a lot of mill-turns, and I'm not sure how any of the techniques shown in the video wouldn't apply in that environment?
Thanks sir .🙂
You're welcome!
Thanks again for video. Great work!
You're welcome as always, Shane :)
Oh I absolutely watched to the end. . . and wanted more!

If you have a file you'd like me to do a quick demo on, shoot it over to aeberhard@vector-mfg.com and I'll try to slot it in.
@@VectorMfg Thanks a lot, its a deeper learning for me😊
@@VectorMfgkept your email id. Anytime i may bother you.

Programmers😂😂😂😂😂 this is a part for mill -turn....exclusively😅😅😅😅😅 you waste time.
