Hello all, I am new to Mastercam. I just started learning mastercam 4th axis from the pdf of mastercam 5axis. THe tool in 2axis, follows the 2D path perfectly. But in 4th axis, the path of tool and the tool path does not match. I am attaching few screenshots, to understand this better. ss_1 : toolpath looks good. It's in the wireframe, proper place. ss_2 Going to verify now. ss_3 Is not starting where I wanted. ss_5 is completed pocket. ss_4 the axis rotated and now the pocket is in the place. What is happening here?

Hi guys, Here's what we need. a 6-32 tapped hole thru cast 1/4" thick. Thread minor has to be .109 to .112. Hole is made with .125 carbide drill. The roll tap give a nice minor dia, but were eating thru the taps like no tomorrow. The operator has been going thru about 8 taps a shift. Originally the program had the tap rpm set to 1000 with a feed of 37.5. I thought that was way too fast. the first couple flutes on the tap would get burned up in no time. So i slowed the S&F down. But I dont think I slowed it down enough. Currently its set at S750 F23.4375. I was reading thru some of these forums and many people said that the max rpm for small dia tapping was around 200-250 rpm. If I need to slow the tap down to prolong its life, then I guess thats what i have to do. Only thing that will affect is longer cycle times. What are your thoughts on this issue? Could I start with a smaller hole and use a plug tap? Is it the coolant? What variables am i missing? Thanks, Matt
