Investigation of the influence of NC controller and control mode by machining tests of blades on machining time

Abstract

In this study, position and angle commands of each axis when machining the same blade shape with a 5 - axis machining center with different NC were recorded and the influence of NC type and control function on cycle time and velocity fluctuation was investigated. As a result, it was found that the cycle time is greatly shortened by using tool tip point control. In addition, the relative velocity is influenced on NC controller, acceleration or jerk is limited.
