Five-Axis Numerical Control Processing Application and Surface Quality Control of HyperMILL-Based Mobile Phone Mold Cavity
The mold cavity structure of mobile phones is one of the most typical complex surface structures. Specific to this type of product, this paper takes some typical product as an example, to conduct Hyper Mill-based analysis and computation for surface processing quality control problem in numerical control milling on the basis of the analysis of traditional mobile phone cavity processing. The description of five-axis processing and path as well as VERICUT simulation is explained with the final application verification. The result shows that the quality control formula of the processing surface is consistent with the actual situation, and the advantages of five-axis processing technology in the application of such types of products are clarified as well.
Process Analysis and Simulation of Complex Parts
For complex parts, computer-aided machining simulation software can efficiently verify the correctness of the program. This paper deals with a kind of compound parts for turning and milling. Analyze and design their process and processes route. The practical scheme is put forward in view of the processing requirements of structure, stiffness and irregular streamline, then analysis it. At the same time, the technical difficulties encountered in the scheme are analyzed in depth, and verifies its feasibility by simulating it for the proposed solutions. After meeting the various process requirements, the actual machining of the parts is carried out. Verify the results in practice.
Collision-Free Five-Axis Milling of Twisted Ruled Surfaces
Summary Ruled surfaces (generated by straight ruling lines) are a special kind of free form surfaces which plays an important role, e.g., in aerodynamic surfaces (rotary engines). They are particularly well suited for five axis milling by the Bank milling method. In the case of twisted ruled surfaces, however, the obvious milling method of having the cutter touch these ruling lines along a generator of its own flank leads to collision problems. The nature of these twisted ruled surfaces is analysed and conditions for their collision free milling by a cylindrical cutter are established. Efficient milling strategies are found.
