A process plan should bring about reasonably high production efficiency in order to fulfill the production quota before its due date 定额,限额 3. A process plan should ensure low production costs 4. A process plan should help improve the working conditions and promote the uninterrupted development of manufacturing technology Product quality, production efficiency, and production cost are the main technological and economical considerations in process planning. Of these, product quality is of primary Importance In process planning, the first important problem to be resolved is how to achieve the required accuracy to meet design specifications. When a process plan is implemented, it must ensure all the quality requirements as much as possible without relying upon the skills of the operatorSCIENCE AND TECHNOLOGY ENGLISH FOR MECHANICAL ENGINEERING 2.
