Cutter compensation or sometimes referred to as "cutter comp", is an offset or shift from center line of the tools shaft to the cutters edge along a programmed path. The advantage of cutter compensation is the use of geometry based offsets rather than tool center point, allowing for the same program to use different diameter tools.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

What is a ball mill? A ball mill is a size reduction or milling equipment which uses two grinding mechanisms, namely, impact and shear. 1 Unlike other size reduction equipment, such as breakers and jaw crushers, ball mills are capable of producing powders and particulate materials of mean particle sizes within the 750 to 50 micron (µm) range.. Ball mills serve both dry and wet milling ...
