CNC machining (5)

The production process of a machine refers to the whole process of making a product from raw materials (or semi-finished products). For machine production, it includes transportation and preservation of raw materials, preparation for production, fabrication of blank, processing and heat treatment of parts, assembly and debugging of products, painting and packaging, etc. The content of the production process is very extensive. Modern enterprises use the principles and methods of system engineering to organize and guide production, and regard the production process as a production system with input and output.

Product Details

In the process of production, the process of changing the shape, size, position and nature of the production object to make it become a finished product or semi-finished product is called the technological process. It is a major part of the production process. Process: casting, forging, stamping, welding, machining, assembly processes, such as machinery manufacturing process generally refers to the part machining process and machine of the sum of the assembly process, other process is known as the auxiliary process, such as transportation, storage, power supply, equipment maintenance, etc. The technological process is also composed of one or several sequential processes, and a process consists of several working steps.

The technological process

The working procedure is the basic unit of the machining process. The so-called process refers to a (or a group of) workers, on a machine tool (or a work place), for the same workpiece (or for several workpiece at the same time) by the continuous completion of that part of the process. The main characteristic of forming a process is that the object, equipment and operator are not changed, and the content of the process is completed continuously

The working step is under the condition that the machining surface, machining tool and cutting amount remain unchanged

Walking knife is also called working stroke, is a processing tool on the processing surface of a complete processing step.

The formulation of mechanical processing process, must determine the workpiece to go through a number of processes and the sequence of the process, only list the name of the main process and the processing sequence of the brief process, known as the process route.

The formulation of the process route is to formulate the overall layout of the process, the main task is to select the processing method of each surface, determine the processing sequence of each surface, as well as the number of the number of the entire process. The formulation of process route must follow certain principles.
