4 Document form of process specification and its scope of use 4.1 Process card: mainly used for products produced in single piece and small batches. 4.2 Process card: used for various batch-produced products. 4.3 Process card: mainly used for products produced in large batches and key processes in single piece and small batch production. 4.4 Operation instruction card (operation instruction book): used to establish the process quality control point. 4.5 Process code: general operation requirements that a certain profession should abide by. 4.6 Inspection card: used for key process inspection. Approved by the State Machinery Industry Bureau on November 16, 1998, implemented on December 1, 1998
JB/T9169.5-1998
4.7 Adjustment card: used for automatic and semi-automatic machine tools and spiral bevel gear machine tool processing. 4.8 Rough drawing: used for the manufacture of rough parts such as castings and forgings. 4.9 Process drawings: used in conjunction with process or process cards as needed. 4.10 Assembly system diagram: used for the assembly of complex products, used in conjunction with assembly process cards or assembly process cards. 5 Basic requirements for designing process specifications
5.1 The process specification is an important technical document that directly guides on-site production operations and should be correct, complete, unified and clear. 5.2 On the basis of making full use of the existing production conditions of the enterprise, advanced process technologies and experiences at home and abroad should be adopted as much as possible. 5.3 Under the premise of ensuring product quality, productivity can be improved and consumption can be reduced as much as possible. 5.4 Safety and industrial hygiene measures must be considered in the design of process specifications. 5.5 Parts with similar structural characteristics and process characteristics should be designed with typical process specifications as much as possible. 5.6 The process specifications of various professions should be coordinated and consistent during the design process and should not contradict each other. 5.7 The size, format and filling method of the process specification shall comply with the provisions of JB/T9165.2. 5.8 The terms, symbols and codes used in the process specification shall comply with the provisions of the corresponding standards. 5.9 All measurement units in the process specification shall use legal measurement units. 5.10 The numbering of process specifications shall be in accordance with the provisions of JB/T9166. 6 Main basis for designing process specifications
a) Product drawings and technical conditions;
b) Product process plan;
c) Product parts process route table or workshop division of labor detailed table d) Product production program;
e) Production conditions of the enterprise;
f) Relevant process standards:
g) Relevant equipment and process equipment information;
h) Relevant process information of similar products at home and abroad. 7 Design procedure of process specifications
