摘要:本课题为钛合金的切削加工及专用涂层刀具的设计。通过对钛合金的性能和国内外发展现状进行综述,了解国内外钛合金使用及加工的总体水平。根据实际情况对加工零件进行毛坯、加工工艺设计,对零件加工过程中需要使用的刀具进行设计。整个设计过程首先是对零件加工工艺设计进行设计,包括毛坯的选择、加工方案的制定与加工工序的拟定.其次是对零件加工过程中所使用的刀具进行设计、计算与验算,包括刀具的类型、刀具尺寸、切削参数与尺寸参数。整个设计方案中所选择的切削参数、尺寸参数一部分是根据国标来设定,其余大部分是参照名古屋精密工具股份有限公司实际加工所使用的切削参数来设定的。所使用的机床都参照公司实际所使用的机床进行设计。40965 毕业论文关键字: 钛合金加工;专用刀具设计;刀柄设计;涂层处理
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.
