Whether can we deside the cam tool path in Milling operation .

[abhijayauto]

Hello ,

          I was Programmed for milling slot by using pocket milling my cycle time for this pocket is    

20 Min 16 sec and for the same slot programmer have made the manual program for which cycle time was 3 min 33 sec. so thought this is due to uncontrolled tool path that is the reason i want to deside cam tool path. the project on which i was working is attached in the mail .

         please help me to solve this problem.

When your machinist programmed it at the machine, how much of a depth of cut did he take? In your file, you have it set to 1mm max depth, which isn't a whole lot.

That said, even after playing with a few settings and cleaning it up a bit, it's still quite long. Watching the simulation, I see what's happening, and I think it's a bug. After it machines for a while, it goes back to the top and repeats the whole process over again, essentially cutting nothing....

One of the better workarounds I can come up with is using 2D Contour, which takes all of 2 min 15 sec. File is attached

Seth, Yep, I got 2D contour as well, but I also tried 2D Adaptive with the same tool which should be fine at that size with it`s programmed speeds and feeds, 51 seconds on the Sim for that.

Plenty options for that job, file attached

From a machine integrity standpoint, I'm not fond of narrow channel adaptive toolpaths 🙂

They just sound abusive on some machine tools

Seth, I fully agree, all depends on what machinery the OP has available as to just what toolpaths would be appropriate.

I have done some stuff like this with a friend who has a couple of Hurco TM10 lathes with driven tools and C axes just as excercises exploring the machine capabilities and Adaptive did work well. Having said that we would always program a job like this at the machine due to the Hurco machines having excellect conversational programming a simple contour across and back we can program in a couple of minutes at the control whicle the machine is running another program so any sort of CAM is rarely required 🙂 🙂
