The coordinate comparison method relies on manual reading of the NC program to check, convert, and compare the coordinate values. The workload of the personnel is large and the error rate is high. Moreover, because the coordinate values are not intuitive and lack a visual interactive environment, the cycle of proofreading long, inefficient
The simulation software-assisted proofreading method mainly realizes the proofreading of the NC program through multiple steps such as establishing a proofreading model in the simulation software, configuring the simulation project, setting the processing environment, establishing the proofreading task data group, setting the simulation parameters, running the simulation module, and analyzing the simulation results. , the process steps are many, the process is lengthy, and the efficiency is not high
Especially in the multi-axis machining of small and complex structural parts, although the amount of program is not large, because of the multi-axis machining of NC, the time and cycle of the above two proofreading methods are very long, which seriously restricts the preparation efficiency of NC programs
In addition, in the multi-axis hole machining of complex structural parts, the current trajectory simulation software cannot display the direction of the tool axis vector, and the calibration personnel need to manually establish the tool axis information in the CAD program, which further increases the calibration time and reduces the calibration efficiency.
