Production process
The production process of a machine is the entire process of making a product from raw materials or semi-finished products.
For the production of machines, it includes the transport and preservation of raw materials, the preparation for production, the manufacture of blanks, the processing and heat treatment of parts, the assembly of products, and debugging, painting and packaging. The content of the production process is very broad, modern enterprises with the principles and methods of systems engineering to organise and guide production, the production process as a production system with input and output.
In the production process, any process that changes the shape, size, location and nature of the production object to make it a finished or semi-finished product is called a process. It is the main part of the production process. Process can be divided into casting, forging, stamping, welding, machining, assembly and other processes, mechanical manufacturing process generally refers to the parts of the machining process and the assembly process of the machine the sum of the process, the other process is known as the auxiliary process, such as transport, storage, power supply, equipment maintenance and so on. The process is composed of one or several sequential processes, a process consists of a number of steps.

Processes
A process is the basic unit of a machining process. The so-called work process is that part of the process that a worker (or a group of workers), on a machine tool (or a workplace), on the same workpiece (or at the same time on several workpieces) is completed in succession. Constitutes the main characteristics of a process is not to change the processing object, equipment and operators, and the content of the process is completed continuously
Work step is unchanged in the machining surface, machining tools unchanged, the conditions of the cutting amount unchanged
Tool walking, also known as the work stroke, is a machining tool in the machining surface processing once completed by the work step. The development of machining process, you must determine the workpiece to go through several processes as well as the sequence of processes, only the name of the main processes and their processing order of the abbreviated process, known as the process route.
The formulation of the process route is to develop the overall layout of the process, the main task is to select the processing of each surface, to determine the machining sequence of each surface, as well as the number of processes throughout the process, such as the number of processes. The preparation of the process route must follow certain principles.

Types of production
Types of production are usually divided into three categories:
1. One-piece production: individual production of different structures and different sizes of products, and rarely repeated.
2. Batch production: manufacturing the same products in batches throughout the year, with some repetition of the manufacturing process.
3. Mass production: products are manufactured in large quantities, and most workplaces often repeat the processing of a particular process for a particular part.
