Popis: 1. An improvement of the pneumatic instrument for process control of discontinuous surfaces is proposed by providing it with a damping throttle. The improved instrument has been tested out on a rack and by grinding components. 2. The amplitude of the improved instrument's pointer oscillations in the course of machining the components is considerably reduced, thus making visual control possible. 3. Requirements have been specified for instrument parameters (throttle diameter of 0.4–0.5 mm, pre-throttle chamber volume of 5–25 cm3 and post-throttle chamber volume of 25–30 cm3), for dynamic characteristics, etc. 4. The application of the above method makes it possible to utilize either contact or contactless measuring equipment for controlling splined and castellated shafts and holes. 5. The error in machining castellated and splined shafts and holes by means of the above method forK≥1.7 is reduced by a factor of 1.5–2, and for K≥4 it does not exceed the error of machining smooth shafts and holes.
