Abstract: A new biglide parallel NC grinder for helical drill point machining was developed. The mathematical model for the grinder is simple and makes it easy to accomplish the real-time control. The structure and characteristics of the grinder were introduced. Otherwise, the dynamic model that the biglide parallel NC grinder is machining the helical drill points was developed by Lagrange approach. Moreover, the dynamic simulations based on the dynamic model were done for the grinder with Matlab/Simulink software. The simulated curves can reflect the driving forces of the linear motors and kinematics parameters of the mobile platform of the grinder when it is grinding. The results showed that the simulations are reliable, and the dynamic characteristic of the grinder is satisfied. Therefore, the biglide parallel NC grinder for helical drill point machining has great value in application.
