"Wavy cuts"
1/21/15
I have recently been having issues regarding wavy cuts on angled pieces. It does not occur on 90 degree cuts, only on angles. I am running a 1/2" 2 flute compression bit at 18000 rpm with a feed rate of 21 m./min. it does it regardless of material thickness, size, or cutting direction. Any insight into this would be appreciated. Thank you.

Is that wavy part along the x axis, y axis or both? What kind of machine is this?

The wavy cut is usually on both the x and y axis. I am running a Biesse rover FT with Biesse works.

Had similar issue on our Rover, in our case it was the deceleration/acceleration setting that needed to be adjusted. Also had a similar issue on a Shoda but it was caused by mechanical wear in the drive system.
It would always happen right after a direction change.

Is this a program that is written in Biesseworks? Have you looked at the G-code. Need to rule out program or mechanical. Are you using tool comp? What about decel. dist. (SDS)? This sometimes causes weird things on our Rover G.

It is written within biesseworks and it only does it on angled pieces so i dont think mechanical is an issue as it would do it all the time if the drives were worn. I will experiment with the accel/decell settings amd see if i can remedy the problem.

here is the diagnostic:
measure the waive if its symmetrical it is software programing eror.
if its not, mechanical.

Put your machine in a "E" stop so that your tables / machine head can move freely. Grab your drive screws and give them a rapid shake so that your table will move or the head will move. If you feel or see or hear any lag or slop in the drive screw chances are the are a bit loose and you should tighten them, but not too tight. Call the manufacturer if you need help. This looks like a sloppy x or y axis.
