STUDY ON CHIP FORMATION MECHANISM OF ULTRA-HIGH SPEED PRECISION GRINDING CU AND AL

Article Summary   by:TsingHua     Original Author: Diamond & Abrasives Engineering
ª
 
Physics models of molecular dynamics simulation of ultra-high speed precision grinding process are established. Potential function of molecular dynamics simulation of ultra-high speed precision grinding of monocrystalline copper and monocrystalline aluminum is selected properly. Basal arithmetic and step of molecular dynamics simulation of ultra-high speed precision grinding are researched. Results of molecular dynamics simulation of ultra-high speed precision grinding of monocrystalline copper and monocrystalline aluminum are analyzed and researched. Ultimate surface roughness obtained by molecular dynamics simulation of ultra-high speed precision grinding of monocrystalline copper and monocrystalline aluminum is confirmed. The ultimate depth of deformed layer and the ultimate machining precision are forecasted for ultra-high speed precision grinding of monocrystalline copper and monocrystalline aluminum. Results of experiment show that the minimum thickness of cut is in proportion to the cutting edge radius.
