Thanks Rich
Some useful info there.
Like you say at $20 to $30 per end mill i can't afford to make too many mistakes...
I checked for backlash and runout and am confident my machine is set up well enough for this operation.
The length of cut on the endmill is 1.2mm (0.05") So i'll probably only take it to 0.035" (0.9mm) depth
Your depth per pass suggestions sounds like a good starting point.
I know the feedrate needs to be slow but how slow...?
By the way which has more strength carbide or HSS...?
Thanks again.
