production process

The production process of a machine refers to the whole process of making a product from raw material (or semi-finished product). The production of raw materials, including the transport and preservation, preparation of production, rough manufacturing, parts processing and heat treatment, product assembly, and debugging, paint and packaging content. The production process is very extensive, modern enterprise systems engineering with the principles and methods of production and production guidance, the production process as a system with input and output.

In the production process, any change in the production object shape, size, location and nature, so that it becomes finished or semi-finished product process known as the process. It is the main part of the production process. Process can be divided into casting, forging, stamping, welding, machining, assembly and other process, mechanical manufacturing process is generally refers to the mechanical parts of the process and the machine assembly process summed up, the other process is called auxiliary Process, such as transportation, storage, power supply, equipment maintenance. Process is composed of one or several sequential processes, a process consists of a number of steps. Mechanical finishing

crafting process

crafting process

Process is the basic unit of the machining process. The so-called process refers to a (or a group of workers in a machine (or a work place), on the same workpiece (or at the same time a few pieces of work) that part of the continuous completion of the process. The main features of a process is not to change the processing object, equipment and operators, and the process is the continuous completion of the content

Work-step is in the processing of the same surface, the same processing tools, cutting the same amount of conditions

The tool is also called the working stroke, is the processing tool in the processing of surface processing once completed the work step. [1] 

Formulate the machining process, we must determine the workpiece to go through a number of processes and the sequence of operations, only the name of the main process and the processing sequence of the brief process, known as the process route.

The preparation of the process is to develop the overall layout of the process, the main task is to select the surface of the processing methods to determine the surface of the processing sequence, as well as the whole process of the number of processes and so on. Process routing must follow certain principles.

Production type

Production types are usually divided into three categories:

1. Single-piece production: Individual production of different structures and different sizes of products, and rarely repeat.

2. Mass production: The same products are manufactured in batches each year, and the manufacturing process has a certain degree of repeatability.

Mass production of parts

Mass production of parts

3. Mass production: A large number of manufacturing products, most of the workplace is often a repeat of a particular part of a process of processing.

Process planning design

Design Principles:

(1) the design process should be able to ensure that the machine parts processing quality (or the quality of the assembly of the machine), to design drawings on the provisions of the technical requirements.

(2) the process should have a higher productivity, so that products on the market as soon as possible.

(3) to reduce manufacturing costs

(4) pay attention to reduce the labor intensity, to ensure production safety.

Source:

(1) product assembly drawings, parts drawings.

(2) product acceptance quality standards.

(3) the annual production program.

(5) production conditions, including machine tool equipment and process equipment specifications, performance and existing state, the technical level of workers, factory-made process equipment capacity and factory power supply, gas supply capacity and other relevant information.

(6) process design, process equipment design required design manual and the relevant standards.

(7) domestic and foreign advanced manufacturing technology information.

Step Content:

(1) analysis of product assembly drawings and parts drawings.

(2) to determine the rough.

(3) to develop the process route, select the positioning of the base surface.

(4) to determine the process used in the equipment.

(5) to determine the process used by the tool, fixture, measuring tools and auxiliary tools.

(6) to determine the main process of the technical requirements and testing methods.

(7) to determine the process allowance, the calculation process size and tolerance.

(8) to determine the cutting amount.

(9) determine the working hours quota.
