CNC Routing Basics: Toolpaths and Feeds 'n Speeds Make:

Calculating Feeds and Speeds. Below is a formula for calculating feed rate: ChipLoad x CutterDiameter x NumberOfFlutes x SpindleSpeed = FeedRate. Where chipload is the amount of material cut per tooth (feed per tooth). Feed rate is the surface speed of the cutting tool in inches per min, spindle speed is the rotational speed of the cutting tool

Frequency domain characterization of torque in tumbling ...

 · For a specific load and operating conditions, the torque appearing in a tumbling ball mill is a highly variable magnitude in the time domain. This fact is due to the operating principle of ball mills, which is based in the elevation process of balls and material from the toe region to the shoulder region of the drum.
