Abrasive blasting systems typically include three basic components an abrasive container ie blasting pot a propelling device and an abrasive blasting nozzle s The exact equipment used depends on the application The three propelling methods used in abrasive blasting systems are centrifugal wheels air pressure or water pressureMICRO MACHINING PROCESSES PROF V K JAIN dr V K JAIN ability to machine anisotropic and suspended structures on the same substrate After a certain value of abrasive flow rate abrasive flow velocity decreases to the extent that it results in reduction in MRR
