Discuses the way and the method of relating design between part and assembly modeling,the way and the method of the assembly simulation and the interference detection.

All those approaches, Parametric feature modeling, variational design, linkage design between part and assembly, assembly simulation, interference detection.

An optimized algorithm for cutter spacing path and a new gouge-detection algorithm for CNC machining were developed in which all the scallop height values between adjacent tool-paths are equal to the maximum allowance,so the maximal cutting width can be obtained and the gouge can be avoided.

Enveloped surface method in interference detection between opening and closing mechanism of lids of high speed train;

In the meantime, the virtual assemble of redactor has been given by relating the three-dimensional omponent packing and interference detection system.

The product design module is developed,which can realize grab virtual assembly,kinematics analysis,interference check,finite element analysis and creating engineering drawings.

Research on method of interference examination in NC programming for screw machined by disc milling tool;

Research on Modeling and Interference Checking of Assembly Simulation;

The work is achieved on the bases of Pro/E and C language,and included 3 modules: loading the model and pretreatment,creating the simple disassembly path,interference checking based on containing box de.

Therefore, the research for layout, interference checking and simulation for bending pipe machine is proposed.
