Research on Modeling and Simulation of Linearity Controlling in Gun Drill Machining

With the diversified market demands, the high precision deep hole processing increased and the difficulty coefficient has been getting greater, Therefore, how to improve the deep hole linearity problem is also imminent. This article studies on the linearity deviation problems in the process of small deep hole processing which diameter is between 3 and 16. From the parameters of gun drill cutting tools, accessoties of machine, and the vibration system of machine tools in the machining process, etc., to discuss the reasons affecting the linearity and put forward corresponding solutions for various influencing factors. Finally through computer analysis software and experimental means to verify the feasibility of the scheme.
