Toolpath and Holes Accuracy of Robotic Machining for Drilling Process (original) (raw)

Lecture Notes in Mechanical Engineering, 2019

Abstract

Drilling is one of the major machining operations in manufacturing. The application of robots in machining is the alternative technique to produce new products of the future. However, the performance of the robot always been a challenge in production. This paper presents the investigation on the effect of arm robot itinerary, holes orientation and materials type on holes accuracy and toolpath angularity of Aluminum Alloy 6061 (Al 6061) and High-density polyethene (HDPE). A series of drilling experiments by using COMAU robot with 24 runs were conducted at difference combination parameters. The measurement on hole accuracy and toolpath angularity were done by CMM machine. Response surface methodology (RSM) was used as a design of experiment (DOE) for optimization. Evaluation by ANOVA showing that the interaction between arm robot itinerary and material type found to be significant factor for the hole accuracy whilst the orientation of the hole dominant factor affecting the toolpath an...
