机械制造技术基础课程设计指导书（Guidelines for the course design of mechanical manufacturing technology） Guidelines for the course design of mechanical manufacturing technology (tool section) Design objectives and requirements: Tool course design is a mechanical manufacturing (cold processing) professional students in the mechanical manufacturing technology foundation, machinery manufacturing. Equipment design and other related courses after the implementation of a practical teaching link, its purpose is to consolidate and deepen the rationale On the content of teaching and training students to use the theory synthetically and solve the problem of cutting tool design in production practice. Through tool Curriculum design should enable students to meet the following requirements: (1) master the design and calculation methods of several typical cutting tools, (two) learn to draw the tool working drawing and mark the necessary technical conditions, (three) learn to use various design materials, manuals and national standards, Design content: The design of cutting tool course is chosen from shaping tool, forming milling cutter, broach, indexable tool or indexable milling cutter Two designs are carried out, and each tool design includes: 1. tool work drawing: 1; 2. design calculation manual: 1 copies (no less than 3000 words). Two. Design the general steps of cutting tools (1) determine the type of tool; (two) select tool materials; (three) determine the reasonable geometric angle of cutting tools; (four) determine the tool structural parameters (including cutter size, cutter tooth number, cutter tooth and groove shape and size, and tools The structure and size of the gripping part; (five) design and calculate the profile of tool; (six) formulate reasonable technical conditions (including tolerance of important size, shape and position tolerance, and roughness of each important surface), Requirements for tool materials and heat treatment, etc.; (seven) consider the manufacturing process
