Abstract
The cutting force is an important parameter in control and management of the machining processes. A system for measuring and registering the cutting forces in the process of machining the complex profile ceramic parts for aviation purposes was designed, developed and tested making it possible to measure with reference to the machined area height (to the Z coordinate) on the existing numerical control system. KF5P1-5-200 strain gauges with a full-bridge connection scheme were selected as the deformation sensors. Deformation of the grinding spindle body of a special machine with the SA950S30F4K.01 numerical control exposed to action of the cutting force radial component was assessed, and the zone of maximum stresses was determined, where the strain gauges were installed. The system was calibrated to measure the cutting forces using the developed power frame and the reference dynamometer. Software was created that makes it possible to register and analyze the data obtained, as well as to visualize the process of measuring the cutting forces in real time during the ceramic parts machining. Based on the results of testing the developed system and software, the possibility was established to measure the cutting forces during machining the complex profile ceramic parts, to visualize, register and print the results. Such a system could be used in the scientific research laboratories and pilot production in the ceramic parts machining.
