The research of surface waviness control technology for 5-axis flank milling

This paper presents a comprehensive surface waviness control technology for 5-axis flank milling. Through constructing dual NURBS curves to describe toolpath, the feedrate and rotary axis optimization method is proposed. Through controlling milling area rate, the proposed method could improve the 5-axis flank milling state under the constrains of cutting force, machining dynamics conditions and driver physical limits. In addition, it could improve the rotary axis unstable movement such as discontinuous and reciprocating rotating in minor angle to alleviate the unstable of rotary axis. Finally, a series experiments were conducted. The results show that the control technology is effective and applicable.
