Performance evaluation research for velocity planning based on the spatial domain

Abstract

ABSTRACT In order to ensure the machining effect, a flexible velocity planning method is generally adopted to make the motion parameters, such as speed, acceleration, and Jerk continuous. The longitudinal continuity of motion should be ensured in machining as much as possible, and the continuity of motion between adjacent toolpaths should also be ensured, which is called lateral continuity. Therefore, a velocity planning performance evaluation method based on the space domain is proposed. The real-time data from the CNC system are collected to establish the corresponding relationship between the data with motion parameters and the spatial point. According to the different size and intensity of the data, the gradual color method is used to match the corresponding spatial point, and the color is uniformly changed to determine the continuity of the velocity planning on the longitudinal and laterally spatial domain. An example results show that the method is simple and efficient, and performance can be a good evaluation of velocity planning.
