What is the difference between the technical secondary school CNC major and the mold Does the CNC ma

CNC major and mold design and manufacturing major have secondary school studies, there are also junior college studies, the difference is that the college can be slightly higher than the secondary school knowledge. However, the level of ability is related to the level of practice, and it is not enough to rely on knowledge alone, but on experience. When it comes to the design and manufacture of molds, we have to talk about CNC machining.

The machining center is characterized by high precision and high efficiency, and the forming module of the processing mold is the best. Therefore, the CNC major definitely includes the processing and production of molds, but the work content is different.

It can be said that CNC machining is a means of processing and manufacturing, and the mold is the process equipment used for mass production (referred to as "mold", such as the wooden mold for moon cakes, the stamping die for car panels, and the plastic mold for washing machines and mobile phone shells). Mold major mainly learns mold design and manufacturing, look at the professional arrangement of each school, some may be divided into different classes that focus on manufacturing, and focus on design, mold manufacturing will use ordinary machine tool processing, CNC machining, EDM wire cutting and other special processing methods. It can be seen that the learning range of the mold is much larger than that of the numerical control.

Of course, CNC majors will generally learn wire EDM.

Both are high-tech types of work, especially molds, just like traditional Chinese medicine, the older the old Chinese medicine is, the more valuable it is, and it will take a few years of accumulation for more than ten years, it will become more and more powerful, I don't know if you can bear this hardship?

Numerical control technology, also known as computer numerical control technology, is the technology that uses computers to achieve digital program control. This technology uses a computer to perform the operation sequence logic control function of the movement trajectory of the equipment and the peripherals according to the pre-stored control program.

Because the computer is used to replace the numerical control device composed of the original hardware logic circuit, the realization of various control functions such as storage, processing, operation and logic judgment of input operation instructions can be completed by computer software, and the microscopic instructions generated by processing are transmitted to the servo drive device to drive the motor or the hydraulic actuator to drive the equipment to run.

The CNC major is to cultivate application-oriented senior technical talents who master the basic theories and basic knowledge of CNC technology and application majors, and can be engaged in production, management, product marketing, equipment maintenance and other work on the front line of production.

Mechanical drawing, AutoCAD, metal materials and heat treatment, common machining technology, metal cutting, Danli CNC machine tool structure, mechanical measurement technology, fitter skills, electrical skills, CNC machine operation and programming, hydraulic and pneumatic transmission, CNC machine tool assembly and maintenance skills, etc.

At present, the numerical control rate of machine tools in China is only, while Japan is as high as 30, and the United States is more than 40. CNC machine tools have been widely used in developed countries, and there is a big gap between the application and promotion of CNC technology in China and developed countries. China will increase 40-500,000 CNC machine tools in a few years, and 60-800,000 CNC professional and technical personnel will be needed accordingly.

Mechatronics is a profession that combines mechanics and electronics with automation.

CNC refers to digital control, which should focus on automation, such as CNC milling machines, CNC lathes and machining centers.

Mold major refers to the major related to mold design and manufacturing.

Mechatronics is relatively extensive; CNC is biased towards the operation of CNC equipment, which is more specialized; The manufacturing in the mold profession now applies more numerical control technology.

CNC prospects: after joining the WTO, with the rapid development of the economy, China is gradually becoming the "world manufacturing center", numerical control rate has become one of the important indicators to measure the manufacturing technology level and economic strength of a country or enterprise (numerical control rate: the proportion of CNC equipment in the number of equipment owned). At present, China's CNC programming, CNC machine tool operation and maintenance personnel are seriously insufficient, which makes CNC technology one of the four major majors in the national talent shortage, and there is a shortage of middle and senior technical personnel, and the value is natural.

As a result, graduates of this program have always been one of the most sought-after professionals in the human resources market, with good working conditions and good pay.

Career direction: Students can be employed in CNC machining technology and CNC machining programming, operation and maintenance of CNC equipment, etc., and can also be engaged in CAD CAM software applications, sales of CNC systems or equipment, technical services, or workshop production management.

The mold needs to master the design process of the mold and the performance of the materials required for design CNC is mainly to operate the CNC machine tool, and it is necessary to carry out digital programming mold against the drawings, in short, the mold is a tool used to form items, this tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the item through the change of the physical state of the molded material.

According to the different materials formed, molds can be divided into metal molds and non-metal molds. Metal molds are divided into: casting molds (non-ferrous metal die-casting, steel casting), and forging molds; Non-metallic molds are also divided into:

Plastic molds and inorganic non-metallic molds. According to the different materials of the mold itself, the mold can be divided into: sand mold, metal mold, vacuum mold, paraffin mold and so on.

Among them, with the rapid development of polymer plastics, plastic molds are closely related to people's lives. Plastic molds can generally be divided into: injection molding molds, extrusion molding molds, gas-assisted molding molds and so on.

Large-scale production of non-sheet metal steel parts - cold heading, die forging, metal molds and other sheet metal discharging - hot rolling, cold rolling, hot coiling, cold coiling.

Sheet metal processing – drawing, expanding, bending, punching, blanking.

Non-ferrous metals – die casting, powder metallurgy.

Plastic parts - injection molding, blow molding (plastic bottles), extrusion (pipe fittings) numerical control, CNC technology is also called computer numerical control technology, at present, it is the use of computer to achieve digital program control technology. This technique uses a computer to perform the control function of the equipment according to a pre-stored control program. Because the computer is used to replace the original numerical control device composed of hardware logic circuits, the realization of various control functions such as storage, processing, calculation, and logic judgment of input data can be completed by computer software.

The mold is the frame that makes the product shaped, and CNC is the equipment required to process the mold. If you ask to learn, the mold depends on the hand, and the CNC depends on the machine.

CNC is for molds. CNC general index control lathes and CNC milling machines, the basic processing of molds are completed by numerical control, such as the basic shape of the shape and product parts. The details are handled by the molder.

1. The definitions are different. CNC is a method of using digital information to control mechanical movement and machining process; A mold is a tool used to make molded items.

2. Different application fields.

CNC technology involves many fields: (1) mechanical manufacturing technology; (2) Information processing, processing and transmission technology; (3) automatic control technology; (4) Servo drive technology; (5) sensor technology; (6) Software technology, etc.

Molds are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, as well as the forming and processing of compression molding or injection molding of engineering plastics, rubber, ceramics and other products.

CNC and mold have something in common, the mold needs CNC machining, and CNC machining can do mold. CNC points: CNC operation and CNC programming, CNC operation is very simple, generally a few days to learn, learn fine points and not a month. CNC programming is relatively difficult, and general CNC programming has.

For those with more than four or five years of work experience, the salary is generally about 3,000 to 6,000. The mold has mold fitter, mold programming, mold design and other work! The above is:

Nantong Kexun Education] to answer for you: Nantong Kexun Education is a comprehensive training institution that integrates mold design (CAD, UG and PROE) advanced applications and CAM programming (UG, CIMATRON, POWERMILL and MASTRCAM) training and provides enterprises with mold design, product modeling and CNC program solutions.

CNC is used to make molds, and molds are used to make products. The relationship between CNC and mold can be referred to as a parent-child relationship. Some molds can't be done, just do it on the CNC.

What are you referring to? Is it a major in school, or does it refer to a job outside or the relationship between the fields to which the two belong? If it is a major in the school, CNC learning is the operation and programming of CNC machine tools, while the mold major should be learned more widely, such as some simple CNC programming, simple mold design and parting, and the theoretical operation of EDM wire cutting CNC machine tools.

If it is a job position, CNC can be operated and programmed; The range of molds is a bit wider. If it is a relationship, CNC machine tools must be used when the mold requires high precision, but the production of the mold does not necessarily have to have a CNC machine tool, such as the production of casting molds.

The high precision requirements of the mold must use CNC machine tools; The numerical control technology is the most widely used in the mold profession, like the general mechanical parts only need to be programmed by hand, and the mold cavity is mostly complex surface, must use CAM software programming and then post-processing. In fact, it is not a question of what you want to learn, but a question of what you can learn, it is impossible for you to have the opportunity to do mold design after graduating from mold, do you believe that you go to the talent market to see if someone wants inexperienced people to do design? Really to do a good job in mold design must start from mold processing, all kinds of machine tool processing, process tooling fixture design, mold fitter, mold ** to understand, it can be said that you did not stay in the workshop for three or five years, is to let you engage in mold design, you are also a mediocre.

CNC machining technology is a tool that belongs to machining, that is, machining.

Mold is divided into: mold design, mold manufacturing, mold processing.
