What is CNC:Everything You Need to Know


What Is CNC?The abbreviation of Computer Numerical Control knows the object of its operation from the name. The computer is the carrying tool for conveying operation instructions, and the digital code is a freely defined instruction. The process and control of digital instructions communicate specified behaviors to computers. Then the computer realizes the operation of the numerical control machine and completes the production task.

This blog post mentions the benefits, how it works, and the industries that involves. Of course, there are other aspects of NC information in this article that you need to continue reading and exploring.

What is CNC?

What is CNC? After understanding the definition of CNC, Tirapid had to mention the reason for the existence of CNC.

The rapid development of the times makes the manual labor mode unable to meet the technical height and personalized production requirements required for production.

In the torrent of the times, technicians have made a lot of efforts in updating production equipment. When the new numerical control production mode enters the manufacturing industry, it changes the traditional production efficiency and capacity.

Through continuous technological upgrading, CNC is more and more suitable for industrial development needs. Therefore, CNC has always served our production and exists in our production activities.

Advantages Of CNC

You know CNCs exist, and you might be wondering why CNCs are in such high demand. Then in this blog post on what is CNC, you will be enlightened by the advantages of CNC.

1. Numerical control ensures precision standards. In CNC operations, the operator calibrates the working position of the cutting tool and the machine tool. And through the positioning operation to implement strict tolerance machining. Then the equipment monitors the quality of the work to ensure that the product meets the standard accuracy.

2. CNC ensures consistent production. CNC machine tools are one of the processing equipment for mass production by manufacturers. The precise operation of mass-manufactured products on the machine tool can achieve the effect of consistent quality and shape.

3. CNC reduces misoperation. Human intervention is a common way of operation in traditional processing. CNC uses design and auxiliary software to regulate the operation. The operation automates the processing of the products, reducing the operational failures caused by humans.

4. Numerical control breaks through technical challenges. The CNC can reach the accuracy range of +/-0.01mm and the processing requirements such as thread making and tapping. Complex processing features are a great challenge to traditional manufacturing techniques.

5. CNC enables innovative possibilities. Numerical control meets prototype custom projects with a variety of operating techniques. It allows engineering designers to make more changes and innovations to products. Traditional craftsmanship is not enough to meet the innovative conditions of diversified production.

6. CNC reduces production costs. machining serves the final finished product through monitoring or feedback. It sags the rework probability of defective products and reduces the time and cost of human operation.

The advantages of CNC are countless, and the above are just some of its significant benefits. By understanding this blog post, you will find more exciting things about CNC.



CNC Operating Procedure

The operation of the CNC system is for the processed products to meet the design conditions for production, but how does it perform operations? Through the following process, you will have a clear idea of the working principle of CNC.

  • Design

When the processing plant receives the customer order, the design experts will use CAD software to research and design the product drawings.

  • Programming

Programming is the next step in design. At this stage, engineers use CAM software to convert operation instructions into machine language (G code) to ensure accurate execution of machining operations.

  • Setup

This step is to install specific fixtures and tools at the appropriate places on the machine tool. Its approach prevents machined products from shifting from the machine tool during operation.

  • Transmission

In general, the data is sent from the computer to the control system of the machine tool through the network or USB transmission.

  • Feedback

After performing the operation, the engineer adjusts the tool information and the cutting condition of the machine tool through the sensor feedback system.

  • Inspection

In the last step of CNC operation, experts will inspect the accuracy, quality, specifications, and other aspects of the finished product.

CNC Machine Tools

As an automated operating system, CNC performs processing tasks by running machines. Machine tools will make corresponding operations by receiving CNC commands. Here is a blog post on what is CNC to introduce you to machining operations:

1. 3~5 Axis Milling Machine

They process CNC products in a multi-axial manner. The CNC company will provide customers with suggestions on choosing 3~5-axis machine tools according to their processing conditions and budget.

2. Lathe Machine

It is a lathe that uses material reduction as its operating method. Products through turning operations can reach ±0.01mm, which has processing advantages in round and cylindrical processing features.

3. EDM Machine

It is a machine tool capable of handling firm materials and deep cavity machining operations. One thing worth noting is that it is not suitable for processing plastics.

4. Boring Machine

It is one of the machine tools mainly for hole processing operations and includes boring, drilling, reaming, and other processing operations.

5. Swiss Lathe

It is a machine tool that processes material with automated infeed, capable of non-stop CNC operations. It has significant advantages in handling slender and small workpieces.

Waterjet Cutting Machine

It is an environmentally friendly machine for precise cutting by adjusting the water pressure. And its operation does not generate heat, avoiding the risk of heat damage to the product.

When it comes to CNC, people tend to associate machine tools in their minds. But CNC and CNC machine tools are two different concepts. In a sense, the scope of CNC covers the content of CNC machine tools.
