Development of a virtual model of five-axis coordinate measuring machine

A new five-axis coordinate measuring machine virtual model is developed, but yet which adds more parameter errors due to the addition of more axis. Through the analysis of the axis errors configuration of five-axis coordinate measuring machine, homogeneous transformation matrix is used to established a structure model of five-axis coordinate measuring machine, and then, measuring software is combined with new utensils on the error multistage correction of the virtual model. Finally, with the help of a simulation example, demonstrating this virtual model of five-axis coordinate measuring machine effectively improved the convenience and accuracy of the measurement. The virtual machine is used to mimic real time measurements in order to come up with estimates for the task specific measurement uncertainty.
