How to master CNC router operation

Contents:

CNC machines have long since established themselves as indispensable tools in industries from small to large. That is why the skill of working with these machines is becoming more and more in demand every year. Logical would be the appearance of the question – ‘And how to learn to work on such a machine?’. In this article we will tell you why it is not as difficult as everyone thinks and where to get the knowledge of using such a machine, regardless of whether you want to learn it as a profession or you just bought a machine in the garage and want to learn how to use it.

CNC router operation and what it is used for

CNC milling machines are quite versatile ones. It can be used to machine metal, wood, plastic and composites. In addition, they are able to:

• Provide full automation of production, almost eliminating the human factor;
• Perform complex operations with maximum precision.

What skills are required to work on a router

The following skills are required to work effectively with a CNC router:

• Knowledge of CNC machines: understanding of the basic components and operation of CNC machines such as:
  • Spindle 
  • Portal
  • Bed
  • Collet chuck
  • Motor
  • Work table
  • Cutter

For example, it is extremely important to understand what material and for what purposes this or that cutter is suitable, by the way, we wrote about it here.

• Knowledge of CNC programming: G-code and CAM: ability to read and write G-code that is used to control machine movements. Skills in CAM (Computer-Aided Manufacturing) software such as Fusion 360, Mastercam or SolidCAM to help create control programmes for CNC machines.

How do I learn to work on a CNC machine?

At the moment, there are many channels with information about machines, from their build to an OS. For example:

• Courses: a lot of training institutes and specialised centres provide their services. In such courses, you can learn the theory and practice of CNC machines to the fullest.
• Video lessons: platforms like YouTube are a great storehouse of knowledge about everything, including machine tools. There are thousands of authors who talk about and teach how to work on CNC milling machines. The key is to find a reliable author whose information you can trust. Also very often a lot of useful information about the machines themselves or their structure can be learnt from the channels of the manufacturers themselves. We cover this and more on our YouTube channel Wattsan.
• Books & articles: of course, the world of machine tools like any technology industry is evolving at breakneck speed. However, some basic information can still be gleaned from them. Articles are more relevant, they are published much more often and in addition to this, nowadays every author or company has a blog on their website, social networks or Telegram, where you can often find detailed information about the operation of machines, their components or the materials they work with.

The main mistake of beginners: neglecting safety techniques

• Protective equipment: this includes safety goggles, gloves and, if necessary, special protective clothing.
• Equipment inspection: the machine, although reliable, is still a machine whose consumable parts can become damaged and, if neglected, can cause damage not only to the machine but also to the operator. 
• Order and cleanliness: a clean working area not only prolongs the life of the machine, but is also a sign of professionalism. 
• Check the programme: before starting the machine, it is important to check that the programme is correct to reduce the risk of rejects and save time. 
• Switch off the machine: always disconnect the machine from the power supply when servicing, setting up, moving the machine.
