The control strategy on a 5-axis grinding machine system is also developed to implement the designed kinematic model. The needle tip's motions in the grinding process are simulated to characterize the effects of grinding parameters on needle tip properties and to predict the trajectory of the needle tip point during the grinding process.Web
