机械设计中零件几何精度的合理应用

Reasonable application of geometric precision of parts in mechanical design

机械零件的几何精度影响产品的质量、生产成本与经济效益,正确合理地选用机械零件的几何精度是机械技术人员的重要任务.为了合理应用好零件的几何精度,从实际应用的角度出发,探讨几何精度应用过程中容易忽视的原则和方法,给使用者在实际应用中提供一定的参考和借鉴,以处理好质量和经济效益二者之间的矛盾.

Mechanical parts′geometric precision affects the quality of the products,the production cost and the economic benefits.It is an important task for the mechanical technicians to choose geometric precision correctly.In order to use the geometric precision of parts reasonably,the mechanical technicians should obey the principles of practice.This article discusses the principles and methods easily ignored during the application process of the geometric precision in order to provide certain reference in the process of practical application for the users to deal with the contradiction between quality and economic benefit.
