Error Analysis of Effects of Workpiece Coordinate System Misalignment When Measuring on a Coordinate Measuring Machine
نویسنده
چکیده
Ever since the introduction of coordinate measuring machines (CMMs), their measuring accuracy has been studied. Much research work has focused on the accuracy characteristics of the measuring system, e.g. the static errors and dynamic errors of the machines. However, the additional error sources can be introduced when a measuring coordinate system is set up. This paper describes how to analyse the error sources when the measuring coordinate system datum is non-coincident with the measuring features datum. In conclusion, the mode of the error sources and suggestions for reducing the additional errors will be given.

Error Recovery by the Use of Sensory Feedback and Reference Measurements for Robotic Assembly
Industrial robots need instrument or parts transport to do which requires coordinate to show the robot’s instrument, parts and body. When investigating the robot location, we are usually interested in measuring its location relative to a reference coordinate system. In this system it is attempted to make the assemble direction smaller by designing the sensor board and making use of an instrumen...
