Hi there!

I hope I make sense, Im very new to cnc machining so please bear with me…

Figuring out how to best profile and pocket 30mm mdf with a 20mm, 70mm stickout, carbide serrated rougher.

When entering values for optional mfg’s Sfc speed(metric), it says to enter in meters but if I enter say 6, the recommended rpm is always below my spindels min rpm(1500-24000)

Should the value be entered in mm instead of meters?

Also, am I supposed to know and enter the chipload data? The roughers manufacturer (kyocera) will or can not give me this data.

thanks in advance!

Ulf, the Surface Speed is indeed meters/minute.  Also, any reputable manufacturer will give you the chipload and Kyocera is certainly reputable.  I don’t know if you’re speaking to a distributor or just the wrong person there, but it borders on preposterous if they tell you the information is unavailable.  If you just can’t get it, you’ll be fine just sticking with G-Wizard’s defaults as they are conservative.
