Machining process specification generally includes the following contents: process route of workpiece processing, specific content of each process and equipment and process equipment used, inspection items and inspection methods of workpiece, cutting amount, time quota, etc.
So in the process of machining, what are the steps to formulate the process specification? Let’s take a look at it
1) Calculate the annual production program and determine the type of production.
2) Analyze the part drawing and product assembly drawing, and analyze the process of parts.
3) Select the blank.
4) Draw up the process route.
5) Determine the machining allowance of each process, calculate the process size and tolerance.
6) Determine the equipment and tools, fixtures, measuring tools and auxiliary tools used in each process.
7) Determine cutting parameters and man hour quota.
8) Determine the technical requirements and inspection methods of each main process.
9) Fill in process documents.
In the process of working out the process, it is often necessary to adjust the contents that have been initially determined before in order to improve the economic benefits. Computer gong processing, Dongguan high-speed computer gong processing, Dongguan mold processing, Dongguan Mechanical parts processing, CNC processing, in the process of implementing the process specification, there may be unexpected situations, such as the change of production conditions, the introduction of new technology and new technology, the application of new materials and advanced equipment, which require timely revision and improvement of the process specification.
The technological process of machining includes, generally speaking, the process of changing the overall dimension and performance of the workpiece through a kind of mechanical equipment.
The working principle of machining process regulation is high quality, high yield and low cost, that is, under the premise of ensuring product quality, labor productivity can be improved and cost can be reduced as much as possible. What problems should be paid attention to in the process planning? Here’s a look:
1., the advanced technology.
In the formulation of machining process procedures, computer gong processing, Dongguan high-speed computer gong processing, Dongguan mold processing, Dongguan Mechanical parts processing, CNC processing should make full use of the existing production conditions of the enterprise, as far as possible, use domestic and foreign advanced technology and experience, and ensure good working conditions.
2. Economic rationality
Under the specified production program and production batch, there may be several process schemes that can meet the technical requirements of parts. At this time, the process cost is generally required to be the lowest through accounting or comparison with each other. Make full use of the existing production conditions, spend less and do more.
3. Good working conditions
