Measuring normal force during internal grinding - using force transducer sandwiched in work steady leg and preloaded by coaxial assembly screw

摘要

The system is used on a machine for grinding bores, internal grooves etc. in which the grinding wheel is mounted at the end of a cantilever spindle arbor. The amount of bending of the arbor during grinding is determined by measuring the normal (radial) grinding force with a force transducer (4) mounted in the leg of a work steady (3, 8). The transducer is sandwiched between the shoe carrier head (5) and base (6) of the steady leg, and the transducer is compressively preloaded by a co-axial assembly screw (7) joining the three parts together. ADVANTAGE - Precise measurement of normal grinding force. Static and dynamic properties of steady remain unimpaired.
