... simulations, a Rotation Tool Center Point accuracy test and an experiment of machining an “S”-shaped test specimen. Originality/value The kinematic calibration approach with the MSVD method and VP method could be successfully applied to the 3-DOF parallel tool head and other 3-DOF parallel mechanisms...

... at different TCP speeds and trajectory radii. Findings – It is found that the tested robots behave differently, and that the static accuracy of these non-calibrated robots varies between 0.5 and 2.3 mm. On the other hand, results show that these three robots can provide acceptable corner tracking at low...

...Ahmed Joubair; Mohamed Slamani; Ilian A. Bonev Purpose The purpose of this paper is to describe a calibration method developed to improve the absolute accuracy of a novel three degrees‐of‐freedom planar parallel robot. The robot is designed for the precise alignment of semiconductor wafers...

...Yeon Taek Oh Purpose Angular errors in the robot axes can make a significant contribution to robot positioning accuracy. This paper seeks to propose a new measuring method for measuring angular errors. Design/methodology/approach New techniques were devised for the detailed investigation...

...Ken Young; Craig G. Pickin Improvements in both robot manufacture and robot controller technology have resulted in greater robot accuracy. A trial has been conducted to highlight the improvements brought by this evolution. By measuring the accuracy of the velocity profiles of two generations...

...Ken Young; Craig G. Pickin The main drawback to programming robots offline lies in the poor accuracy of the robot. Robots are mainly programmed using the traditional teach and repeat method of programming which requires only good repeatability. As a result robots are manufactured with this in mind...

...Mike Oitzman; Joe Campbell Placement accuracy in automated production equipment has been a problem since the first automated machine assembled a product on a manufacturing line at the beginning of the industrial revolution, and the demand for machine accuracy has steadily increased since. Adept...

...Bryan Greenway Discusses robot accuracy and repeatability and the mechanical and control aspects of robots that lead to errors occuring in static positioning and dynamic path following. Outlines the steps that should be taken to minimise errors and concludes that robot users should encourage...
