工艺规划决定了产品的制造方式，因此是制造过程中的关键要素。它在决定零部件成本方面起着重要作用，并影响所有工厂活动、公司竞争力、生产计划、生产效率和产品质量。它是设计和制造之间的关键环节。过程规划活动有几个层次。在产品工程和开发的早期，工艺规划负责确定生产的一般方法。所选择的一般生产方法影响设计约束。在设计的最后阶段，设计师必须考虑制造的容易性，以使其经济。零件设计数据从工程部传输到制造部，工艺规划人员为制造零件开发详细的工作包。尺寸和公差是为工件加工的每个阶段确定的。工艺规划决定了操作的顺序和机床的利用率。还规定了切削工具、夹具、量规和其他辅助工具。确定金属切削和成形过程的进给、速度和其他参数。
Process planning determines how a product is to be manufactured and is therefore a key element in the manufacturing process. It plays a major part in determining the cost of components and affects all factory activities, company competitiveness, production planning, production efficiency and product quality. It is a crucial link between design and manufacturing. There are several levels of process planning activities. Early in product engineering and development, process planning is responsible for determining the general method of production. The selected general method of production affects the design constraints. In the last stages of design, the designer has to consider ease of manufacturing in order for it to be economic. The part design data is transferred from engineering to manufacturing and process planners develop the detailed work package for manufacturing a part. Dimensions and tolerances are determined for each stage of processing of the workpiece. Process planning determines the sequence of operations and utilization of machine tools. Cutting tools, fixtures, gauges and other accessory tooling are also specified. Feeds, speeds and other parameters of the metal cutting and forming processes are determined.
