The formulation principle of machining process planning

The process of making the machining process planning principle is high quality, high yield, low cost, namely under the premise that the product quality is guaranteed, can improve labor productivity and reduce cost as much as possible. Technological advancement in making the machining process planning, should be in full use of the enterprise on the basis of existing production conditions, by domestic and foreign advanced technology and experience as much as possible, and ensure good working conditions. Economic rationality under the rules of production program and production batch, there may be several technical requirements can guarantee parts processing plan, at this time should be through the accounting or contrast each other, the lowest cost of general requirements process. Make full use of existing production conditions, to spend less, do more. Have good working conditions in the formulation process should pay attention to mechanization and automation measures, try to reduce the labor intensity of workers, to ensure the safety of production, to create a good and civilized working conditions. Due to the process planning is one of the important technical documents directly to guide the production and operation, so the procedure should be correct, complete, unified and clear. Terminology, symbols, measuring unit and number used to conform to the corresponding standard. Must be reliable to ensure the realization of the technical requirements in detail drawing. In making the machining process planning, if it is found that part drawing a technical requirements are not appropriate rules, can only put forward the proposal to the relevant authorities, shall not be modified without the detail drawing or not according to part drawing.
