机械制造技术基础复习题（Review of fundamentals of mechanical manufacturing technology） Review of fundamentals of mechanical manufacturing technology Fill in the blanks 1. the operation time in the time quota refers to the sum of the auxiliary time. 2. the order of mechanical processing sequence should be followed,, And four principles. 3. positioning coarse reference shall follow the principle of ensuring that the part machined surface has a certain accuracy relative to the non machined surface,, And in the same size direction, crude standards are generally not allowed to reuse the principles of the four principles. 4. the physical and mechanical properties of the surface layer include the cold hardening of the surface layer, Several aspects. 5., the fixed adjustment assembly method is suitable for assembling, and the number of rings is higher and higher, Machine structure of production type. 6. in the three cutting parameters, the biggest influence on the cutting force is, followed by, and the smallest is the cutting speed. 7. there are three kinds of tool wear: boundary wear and boundary wear. 8. mechanical processing is usually divided into rough processing and three processing stages. 9. machine tool rail error include, The influence of parallelism error between the guide rail and the guide rail on the machining accuracy. 10. when cutting iron parts in CA6140, the tool material is usually chosen as. 11. in the machining of cylindrical surface, machining of carbon steel processing method is adopted for the largest, machining of hardened steel is generally used, and precision processing of non-ferrous metals by. 12. special machine tool clamps have, and clamp specific three basic components. 13. plane processing commonly used methods are, and pull plane and so on. 14. hole processing commonly used methods are drilling, reaming, and. 15. in size chains, the size of an indirect is called. The shape of 16. chips is mainly divided into four types: granular chip and broken chip. 1
