How to solve Chips in milling machine?

[wise318]

1)Anyone can figure out the chips problem due to milling a glass material BK7.?
2) I am using Ichikawa Milling machine where the table rotate and the spindle rotate to mill the material. After do ralf cutting which I set the speed to 60. It produces chips on the edges of the piece.

Welcome to PF, Wise. You might need to clarify your question. I've had limited experience with machine tools, and your terminology is meaningless to me.
I've never heard of 'ralf-cutting', and your number '60' could mean anything from rpm's to depth of cut in thousandths. Please be more specific.

edit: As to the '60', I know that you said that the speed was set to '60', but that could still indicate a progressive depth vs. time as opposed to just rpm's.

First thing I would try is to take a lighter cut at a higher speed with a slower feed rate.
