Animated Simulation of Robot Process Capability

Abstract

To obtain competitive advantages, manufacturers need to stuggle constantly to improve quality and to reduce costs. Computer Integrated Manufacturing (CIM) is a strategy adopted by enterprises to produce high quality products at low cost. One of the common applications in the CIM environment is the deployment of robots. Traditionally, robots are purchased, installed and tested. Significant amount of time and manpower are consumed in the process of decision making in CIM acquisition. In this paper, a graphic simulation and system for robotics operations is developed, in conjunction with a kinematic error model to assist management in making investment decisions. Taguchi-type experimental design is used to predict the robot process capability. Two sets of charts are created by the system to illustrate the repeatability and accuracy of a robot performing a given operation. These charts are histograms in the x, y, and z directions, and scattered ellipses in the xy, yz, and xzplanes. Central to the system are three characteristics: a description of the geometric error and of the kinematic error, a function with which to request and display data on a robot moving from one position to the next, and a family of charts showing the capability of the robot for implementing a required task. The results provided by the system can help management to analyze robotics projects and to make decisions concerning robot selection and implementation in a more systematic manner. © 1995.
