Foshan mechanical processing steps:
(1) Analyze the assembly drawing and part drawing of the product.
(2) Determine the blank.
(3) Formulate the process route and select the positioning base.
(4) Determine the equipment used in each process.
(5) Determine the tools, fixtures, gauges, and auxiliary tools used in each process.
(6) Determine the technical requirements and test methods for each major process.
(7) Determine the machining allowance for each process and calculate the process size and tolerance.
(8) Determine the amount of cutting.
(9) Determine the working hours quota.
Foshan mechanical processing benchmark introduction:
Mechanical parts are composed of several surfaces. To study the relative relationship of the surface of the parts, a reference must be determined. The reference is the point, line, and surface on which the position of the other points, lines, and faces is determined. Benchmarks can be divided into design benchmarks and process benchmarks based on the different functions of the benchmark.
Classification of Foshan Machinery Processing :
Design Benchmark: A benchmark used on a part drawing to determine the position of other points, lines, and faces, called the design basis.
Process benchmark for Foshan machining: The benchmark used for the machining and assembly of parts is called the process benchmark. Process benchmarks are divided into assembly benchmarks, measurement benchmarks, and positioning benchmarks depending on the application.
(1) Assembly basis: A reference used in assembly to determine the position of a part in a part or product, called an assembly basis.
(2) Measurement standard: A reference used to check the size and position of a machined surface is called a measurement reference.
(3) Positioning reference: The reference used for workpiece positioning during machining is called the positioning reference. As the surface (or line, point) of the positioning reference, only the unprocessed blank surface can be selected in the first process. This positioning surface is called the rough reference. The processed surface can be used as the positioning reference in the subsequent processes. This positioning surface is called the fine benchmark.
