Abstract

The invention discloses a method for creating a virtual prototype product of a CMM (coordinate measuring machine). The method comprises the steps as follows: an error field changing with time and space is established; the magnitude and the manner of an influence of an influence factor on a measuring error are analyzed in a virtual error compensation system; an internal or external error source influencing the measurement accuracy is analyzed in the virtual error compensation system; a result of error analysis is tested in a virtual performance test environment; product life-cycle information and a model which are used during simulation are obtained; and the information is extracted to create a virtual product model. According to the method, the high cost is reduced, and the time for tests is shortened. A CMM design process is accelerated, and the performance of the CMM is improved. Finally, CMM developers can reflect market changes promptly.

Description

[0001] Technical field [0002] The invention belongs to the technical field of coordinate measuring machines, and particularly relates to a method for creating a virtual prototype product of a coordinate measuring machine. Background technique [0003] In order to meet the needs of the rapid development of production technology and science in recent years, coordinate measuring machines (CMM) are now widely used in a variety of measurement tasks, their measurement accuracy, speed and performance in harsh environments (such as workshops) The requirements continue to increase. At present, coordinate measuring machine manufacturers improve the measurement accuracy and speed of coordinate measuring machines by designing advanced technologies such as lighter and more rigid structures, high-performance drive systems and control algorithms. In CMM design, problems such as structure and control are closely linked. Therefore, design optimization requires an integrated mechatronics-oriente...
