Is CNC difficult to learn?

Introduction

With the continuous innovation of society and technology, the demand for skilled CNC operators in the manufacturing industry will continue to grow. This means that no matter in the past, present, or future, as long as society is progressing, the manufacturing industry will not withdraw from the stage of history!

In this regard, many people who are interested in the position of machinist want to know: "Is CNC machining difficult to learn?" and other questions.

To find the answer to this question, the author has experienced a lot of practical learning in the CNC workshop. The difficulty can be imagined. The original intention of this blog to write this article is to help all friends who are reading. This blog will explore this issue by analyzing what is CNC, its application, learning guide, and potential career path.

‌Is CNC difficult to learn?

In Chinese idioms, there is a saying that goes "Everything is difficult at the beginning", which means: "No matter what you learn or do, the beginning is the most difficult stage" because, at this stage, your experience is "0". But when you take the first step of learning, everything will become easier and easier.

So what is the difficulty in learning CNC? Let's put this question aside first because you need to understand what CNC is.

What is CNC?

CNC is the abbreviation of Computer Numerical Control. If we only talk about CNC, it means a numerical control center. To learn about numerical control centers, we have to involve systems, and the composition of the system is code. Therefore, CNC should mean a computer control system composed of codes.

In a previous article, we specifically talked about the relevant knowledge of CNC. If you are interested, you can click here to enter after reading this article.

What is CNC used for?

For those who have just entered the industry, you must be eager to know what CNC is used for. Usually, the word CNC is not used alone. We will use it with other words according to the usage scenario, such as CNC programming, CNC machining, CNC manufacturing, etc.

You should have discovered that no matter which combination, CNC is inseparable from production. Therefore, the original intention of CNC is to process or manufacture "some or some objects" through computer numerical control, to obtain the desired CNC products or CNC parts. The object being made is what we usually call raw materials.

What is the difficulty in learning CNC?

CNC (Computer Numerical Control) learning is indeed difficult, which is mainly reflected in the following aspects (mainly CNC programming):

First, CNC programming requires a high degree of precision. For CNC programmers, it is necessary to accurately calculate and guide the movement path of the machine (here refers to the CNC machine tool) to ensure that the processed parts meet the requirements.

Once the calculation or path setting is wrong, it may lead to a decline in product quality or processing failure, so repeated inspections and adjustments are required.

Secondly, CNC programming involves complex programming languages and instruction systems. G code and M code are the basis of CNC programming. These codes involve operations such as motion control, speed regulation, and tool-switching of machine tools.

Programmers need to be familiar with and correctly understand these instructions to write reliable programs. Learning and mastering these programming languages requires a lot of time and effort.

In addition, CNC programming also requires a lot of practical experience and repeated debugging. Programmers must not only complete programming on the computer but also perform actual operations on the machine tool to verify the feasibility of the program. Errors may occur in actual operation, resulting in damage to the workpiece or machine tool failure, which is a great challenge for beginners.

Finally, CNC programming requires programmers to have solid theoretical knowledge of mechanical processing and practical operation skills. Programmers need to understand the structure and performance of machine tools, be familiar with processing technology and standards, and master the operation of related software such as CAD/CAM. These requirements make CNC programming not only a theoretical subject but also a practical skill.

In summary, CNC learning does have a certain degree of difficulty, but through systematic learning and practice, and gradually accumulating theoretical and practical experience, it is entirely possible to overcome these challenges and become an expert in this field.
