OK....if someone can take a look at these numbers and see if there is something glaringly wrong here.
Material is 4140 annealed.
Tool: A brand new Iscar GHDR-25.4-3..........designed for grooving and turning. The tool will cut a groove approx. .38 deep.
Insert: Iscar GIPI 3.18-0.20 IC328 (.125 wide)
Program:
4 GRV OUT O 1 (W) .19 (FV) 441 (Feed) .001 (DEP) .05 (S-CNR) R.005 (SPT-X) 3.07
(SPT0-Z) .815 (FPT-X) 2.475 (FPT-Z) .815 (Rough) 6
Tool sounds like it's trying to groove rocks. Shakes the whole machine. Wearing and breaking the edge of the insert on the first piece. Actually, it acts like the tool is above center......but that could also be from going too fast.
I've grooved on this machine before with a top notch groove tool, and had no problems whatsoever.....so I'm not sure if my program is too aggressive or perhaps my tool isn't any good.
Also.......with this program, as written, does the tool come in and rough the groove out, leaving stock on the side walls for clean up, or does it come right down to the finish Z dimensions ??? I can't tell when I run program check. I must admit, programming a groove in Mazatrol doesn't make much sense. When it asked for a start point, I want to put the start point at the Z dimension closest to the face of the part and the finish Z to the farthest point from the face.....but the machine wants them both at the same point, which is hard for me to wrap my mind around. When I first started putting the start and finish points the way I felt they should be, the tool wants to make a diagonal cut.....which was quite a surprise. Luckily, I caught that on program check !
