Precision mechanical parts, 在设计过程中, must not only meet their functional requirements (i.e., possessing the necessary working capabilities) but also fulfill production requirements during operation. Precision mechanical parts designed for ease of machining and low processing costs are considered to have good manufacturability.
Basic Requirements for the Machinability of Precision Mechanical Parts
1. Blank Selection Requirements
The selection of blanks requires the use of appropriate blank preparation methods in mechanical manufacturing. During operation, methods such as profile making, 铸件, 锻造, 焊接, and stamping are directly utilized. The choice of blank is related to specific production technology conditions, generally depending on production volume, performance characteristics, and machining feasibility.
2. Structural Design Requirements
The structure of precision mechanical parts should be designed to be very simple. Operation primarily involves simple surfaces and combinations, and to a certain extent, the number of machined surfaces and the machining area should be minimized.
3. Precision and Cost Control Requirements
The cost of machining precision mechanical parts increases with increasing precision. This increase is particularly significant at higher precision levels. 所以, high precision should not be pursued without sufficient justification. 相似地, the surface roughness of parts should be appropriately specified based on the actual needs of the mating surfaces.
4. Manufacturability Awareness in Design
To a certain extent, precision mechanical parts machining aims to design parts with good manufacturability. 在设计过程中, it is essential to collaborate with process engineers and learn from them. 此外, basic manufacturability knowledge is provided in metalworking courses and handbooks for reference.
5. Surface Roughness Considerations
The surface roughness of precision mechanical parts is a crucial technical indicator that effectively reflects the microscopic geometric errors of the part’s surface. It serves as a primary basis for inspecting the surface quality of parts during use.
