FLEXURE-BASED DYNAMOMETER FOR DETERMINING CUTTING FORCE
摘要
A high frequency flexure-based dynamometer (10) for measuring vibrations to use in determining cutting forces in a tool. The dynamometer device (10) may operate within a preselected high frequency range while measuring cutting forces less than about 1 N. The dynamometer (10) may include two coupled flexures that interact to produce vibration modes at the edge of a selected bandwidth of interest. These modes may produce a frequency response function within the desired frequency band that has a magnified response and is substantially constant. The dynamometer (10) may include a workpiece (38) mounted to one of the two flexures (12) and a one or more precision accelerometers (30) mounted to the first or second flexures. Finite element analysis may be used to optimize the flexure design.
