CNC machining has been slowly overtaking the conventional machining industry in recent years. One can see this phenomenon as machines, just less serious, replacing human minds.
The word ‘CNC’ simply means ‘Computer Numerical Control’ after all. The technology was first implemented to minimise human effort and make it easier and safer for manufacturing processes. Both CNC machining and traditional machining aim at one target at the end of the day: producing quality machined components.
Therefore, the recent move of major manufacturing firms to use the power of CNC machining over traditional techniques is not a surprise. Industries such as healthcare, military, and aerospace need precise components with tolerances as close as +/- .0005, which with traditional machining is very difficult to achieve. Perfection is not, however, the only thing CNC machining provides.
The key difference lies in their approach and the fact that manual labour is required for one alternative, while the other has 90 per cent automation. Some of the key reasons why CNC machining is becoming the favourite child of everyone are below.
1. Reduced labour costs; One experienced multi-machinery machinist
Every machine requires a dedicated technician with experience, expertise, and thorough knowledge of the machine in hand in the case of traditional machining. In comparison, CNC machining is highly regulated by a software programme and, apart from the initial setup and data feeding, requires very little human interaction. In addition, CNC machining requires less specialised training, reducing labour costs further. With computers playing a major role, a high percentage of the chances of human error and compromised safety in the workplace are also decreased.
2. Large quantity; Maximum quality
Conventional machining is often set for low volume, small-quantity projects because it requires manual effort. However, CNC machines are designed to provide full precision, whether they are responsible for manufacturing a few hundred or thousands of metal machined components.
Their high-quality material gives them to wear and tear resistance, which is prevalent with traditional machining. As a result, with timely yet fast maintenance, they can operate 24 hours a day. In addition, CNC machining uses advanced software, which can be modified according to requirements on a regular basis, to allow super-complex parts to be easily made.
Automated cooling systems often come with CNC machines, lowering the chances of heat damage. For chip control, many advanced computer models come with built-in chip storage and a conveyor belt.
3. The 100x stronger replication of the component is
CNC machines can produce several thousand of 100 per cent identical parts in a record time, a feat that is difficult to accomplish with handheld or traditional machining, designed to monitor precise velocity and positioning. Machines can be programmed to apply the same cut or repeatedly do the same finish without sacrificing the quality of the machined part. On the other hand, traditional machining requires a professional operator to position the tool manually at every stage of the machining process, which will probably take a lot of time and patience. And differences are to be expected, even with such dedication.
4. No Required Prototypes
Simulating designs and mapping their viability involves prototypes. Each producer will chalk out actionable prototypes prior to CNC, test them, and then work on the machining process. This entire routine normally takes several days or sometimes even months when completed manually. The invention of CNC machines ushered in software programming wherein, under practical conditions, you could enter your concept and visually see how you could work with it. This implies no unnecessary costs for the construction of designs, shorter manufacturing times, and a bare minimum labour cost.
5. Complex Parts Production Capacity
At any moment, CNC machines can be reprogrammed and upgraded, giving them the ability to easily manufacture 3D, 4D or even 5D pieces. This makes a smoother change between routine production of CNC machined parts and, if necessary, complex production of parts. In addition, designs can be stored by the app, so you can revisit any desired shape or other design even quicker.
6. Big Eye for Specifications
CNC machining is designed to concentrate on precision; the requirements issued by its operator are continuously maintained by machines. Every step is visually checked during the production process to guarantee the desired effect and measurements.
7. Works for any form of material
This is perhaps the greatest advantage over traditional machining that CNC machining has. Almost any sort of material, including metal, steel, wood, foam, or sensitive plastics, can be used by CNC machines.
8. CNC Adaptability Machining
CNC machining offers a highly advantageous option for producers across a range of industries by offering top-of-the-line performance, precision, and speed for high and low production quantities.
