Research On The Virtual Coordinate Measuring System Of Coordinate Measuring Machines

This paper bings up with the theory of Virtual Coordinate Measuring System. The basic theoretic models of the virtual coordinate measuring system are given. This theory of virtual coordinate measuring system makes use of the principle of Time-Space correspondence and turns the time pulses into spacial displacement. The virtual coordinate measuring system can take place of the scale system in traditional instruments, which has the disadvantages of high cost and difficulty of production.This paper gives the basic theoretic models of two-dimension and three-dimension virtual coordinate measuring systems. By the way of embedding the 2- and 3- dimension virtual coordinate measuring systems into the 2- and 3-dimension measuring instruments respectively, the systematic and random errors of the instruments can be obtained and corrected. The independent virtual coordinate measuring system as a new kind of measuring instrument is also studied in this paper.The experiments of one-dimension coordinate measuring system are also studied. The one-dimension virutal coordinate system is carried out on a three-Coordinate Measuring Machine. The data of the experiments is analyzed.
