Motion of Digital Precision Forming Machine without Pattern Casting and Tool Path Simulation Based on VRML

In this paper, we have researched the digital precision forming machine without pattern casting, and discussed the motion of the machine and tool path simulation technology based on VRML. By updating IndexedLineSet node, we have realized the real-time display of tool path; and by setting DOF node, we have simplified motion simulation of the machine, and completed the synchronous, real-time simulation for motion of the machine and display of the tool path. The final simulation result is approach to the actual operating status of equipment, and the application results are of great theoritical significance and practical application value to design optimization and operation training of the code.
