deep carving cnc production process and technological process



1. production process


the entire process of transforming raw materials into finished products, called the production process. the production process includes: transportation and storage of raw materials, production preparation work, rough manufacturing, mechanical processing, heat treatment, assembly, testing, debugging, as well as painting and packaging< br/>


the production process can be divided into: the production process of the entire machinery, the production process of a part or component; the production process of a factory, the production process of a workshop, etc< br/>


2. process



the process of directly changing the shape, size, relative position, and properties of the production object to become a finished or semi-finished product during the production process is called a manufacturing process. the manufacturing process is the main part of the production process. the main part of the production process in the machining workshop (that is, the entire process of using machining methods to turn the blank into qualified parts) is called the machining process; the main part of the production process in the assembly workshop (i.e. the process of assembling parts into components or complete machines) is called the assembly process



production guidelines and production types


1. production guidelines


the production volume and schedule plan that an enterprise should produce within the planned period is called the production plan. the quantity of qualified products manufactured by a factory in one year is called the annual production plan, also known as the annual output. the production guidelines have a decisive impact on the production process and management of factories. when formulating the machining process of parts, it is also necessary to determine the production plan of the parts. the production guidelines for parts are calculated using the following formula:



n=nn (1 α β)



in the formula: n zero; production guidelines for parts< br/>


n&flash; the production program of the product< br/>


n&flash; the quantity of the component in each product< br/>


&alpha& flash; spare parts ratio of parts< br/>


&beta& flash; the average scrap rate of parts< br/>


2. production type



according to the size of the product and the different production guidelines, mechanical manufacturing production is generally divided into three types based on the degree of specialization of the enterprise (or workshop, section, team, workplace)< br/>


1) single piece production



manufacturing a single part (or product) with little or no repetition is called single piece production. for example, the production of heavy machinery factories or repair workshops, and the trial production of several new products< br/>


2) batch production



batch production refers to the repeated production of identical parts (or products) in a periodic manner. eachit's just a single cut
