Theoretical model design for processing internal surfaces of machine parts with free abrasives that ensures the reliability of technological processes in digital manufacturing

The paper presents the research results of vibroabrasive processing variously located part surfaces. An analysis technological possibilities with free abrasives in digital manufacturing was made. dependability issue is considered. Refined dependences were obtained to determine mass metal removed during and steady-state roughness internal surface. features surfaces are revealed, taking into account different ratio length size cross section. In course experi-mental studies, adequacy proposed dependencies confirmed. A as-sessment designed process at stage preparation made, possible spread parameters. make it design highly efficient processes for parts carry out production an automated mode.
