CNC machining is a method of manufacturing that combines computer software and machining tools. These machines used to perform a range of processes such as lathing, milling, routing, and grinding.
These very complex and powerful devices can produce vast quantities of different products in a very short space of time and also provide an accuracy that would be difficult to replicate using more conventional methods. This is partly why they are so popular and regularly used in the car industry, as well as many other industries that require large volumes of standard components.
Although there are many advantages to using CNC machines, they are a few disadvantages too. Here are some of the pros and cons of using CNC machines in the automotive industry.
PROS
They help boost production levels
Due to the sheer volumes that these impressive machines can produce, it will come as no surprise that they are likely to boost production levels. Due to being programmed by a computer, they don’t get tired, they don’t need breaks, and they won’t take sick days. The result, unlike manual labor methods, is a continuous output of goods.
Impeccable accuracy
The accuracy that computer numerically controlled (CNC) machines work to is second to none. Building a car requires hundreds of different elements and parts, and these machines can be programmed to produce every single one of them to exacting requirements.
Precision engineering is essential when it comes to building a car that is safe and well put together, and CNC machinery provides the perfect means to do just that.
Lower skill requirement
Although a degree of training is necessary to effectively and accurately work these machines, it is far less than would be required than when training and recruiting manual machine operators. Once the CNC machines have been programmed, the information is retained and can be used again and again. This not only makes processes faster but also requires less input from the machine operator when a part needs to be produced again in the future.
CONS
They can cause an increase in unemployment levels
As with anything that involves computers, there is usually a sacrifice to be made in terms of the jobs. CNC machines do, of course, require someone to program and operate them, but the number of employees required will be far less than if manual processes were being used.
They come with a hefty price tag
CNC machines are not cheap by any means, so they may be prohibitively expensive for smaller businesses or those with a less than fruitful balance sheet. They must be looked at as an investment that, once up and running, will more than likely pay for itself very quickly.
Parts can be produced quicker, there are likely to be less quality control issues and, as we touched on above, salary levels will also be lower.
To conclude, we think it’s quite apparent that when it comes to CNC machines, the advantages certainly outweigh the disadvantages.
