ABRASIVE JET TREATMENT PROCESS MONITORING METHOD Russian patent published in 2006 - IPC B24C1/00 

FIELD: monitoring of processes of abrasive jet treatment of part surfaces, possibly in machine engineering at applying lubricant in micro-recesses of predetermined depth.

SUBSTANCE: method comprises steps of determining speed of abrasive particle striking upon surface of driven to rotation and then fixed reference sample for further measuring depth of craters. Reference sample is made of the same material with the same hardness as treated part. Reference sample is driven to rotation and abrasive is fed to zone of sample rotation from pneumatic nozzle mounted normally relative to rotation plane. Depth of craters is measured at linear velocity Vo of rotation on radius of abrasive particle striking spot with use of given formula (1). Fixed sample is subjected to abrasive jet treatment with the same abrasive particles. Depth of craters is measured again and striking speed V1 is determined with use of formula (2). Then part is subjected to abrasive jet treatment. Pressure P3 at inlet of abrasive jet nozzle is determined with use of formula (3) for providing predetermined depth of craters.

EFFECT: possibility for providing predetermined depth of lubricant micro-recesses.
