Feeds and Speeds Charts - ShopBot Tools

When chip load is too high, the tool will deflect creating a bad surface finish and, in extreme cases, chip or break the bit. Chip load is a function of three different parameters: feed rate, RPM, and number of flutes on the tool. Chip load is the thickness of the chunk of material taken by a tooth of the cutter. This is determined

Load Capacity - an overview | ScienceDirect Topics

Load capacity is the maximum allowable force that can be applied to a stage in a specified direction while meeting stage specifications. This maximum force includes static (mass × gravity) and dynamic forces (mass × acceleration). Dynamic forces must include any external forces, such as vibrations, acting upon the stage.
