The design on machining titanium and special coating tool
Abstract:This topic for the design on machining titanium alloy and special coating tool. Reviewed based on the performance of titanium alloy and the development present situation at home and abroad reviewed,to understand the overall level of titanium alloy processing and using at home and abroad.According to the actual situation to design and process the rough machining parts,design the tool in the process of parts processing need to use.The whole design process, first of all, is to carry on the design of parts processing technology design,including the selection of blank, the processing plan formulation and processing process.The second is the tool of parts used in the manufacturing process of design, calculation and analysis, including the type of tool, the size of the cutter, cutting parameters and size.The whole design scheme of the choice of cutting parameters and size part is set according to the national standard,most of the rest is reference to Nagoya precision tool co., LTD., the actual processing of cutting parameters to set.Machine tools are used by reference to the company used in actual machine design.
Key Words:Machining Titanium；Special Tool Design；Fixture Design；Handle Design Coating
