![]() Feeds, speeds and other parameters of the metal cutting and forming processes are determined. Cutting tools, fixtures, gauges and other accessory tooling are also specified. Process planning determines the sequence of operations and utilization of machine tools. Dimensions and tolerances are determined for each stage of processing of the workpiece. The part design data is transferred from engineering to manufacturing and process planners develop the detailed work package for manufacturing a part. In the last stages of design, the designer has to consider ease of manufacturing in order for it to be economic. The selected general method of production affects the design constraints. Early in product engineering and development, process planning is responsible for determining the general method of production. There are several levels of process planning activities. Evaluate any tolerance quickly and easily. Free ISO Metric Tolerance Zone calculator. ![]() According to DIN ISO 2768-2 Tolerance - class General tolerances for straightness and evenness in m m Range of specified size in mm to 1 0 above 10. It is a crucial link between design and manufacturing. Selection of the tolerances displayed in the reference table Basic usage flow. 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. Process planning determines how a product is to be manufactured and is therefore a key element in the manufacturing process.
