CNC Machining Vs Manual Machining: Which is Better?
For manufacturing different goods, most industries prefer CNC, i.e. computer numerical control machining method as this has emerged as the most efficient manufacturing method. In CNC manufacturing, programmed computer software moves different machinery and tools. A CNC specialist is often employed to work with this software and machines so that things can work efficiently.
However, before CNC technology came into existence, the manual machining method was used by most industries. In this system, one technician was required to handle one machine.
After the advent of the CNC system, most industries now rely on this method. However, manual machining is still used by some industries very often. It is good to take note that the right selection of manufacturing methods can lead to successful projects.

And to understand the difference, you should first know what CNC manufacturing is.
What Is CNC Machining?
Designing and building tools and machines using computer software that has been pre-programmed is known as CNC machining. The majority of industries currently use this newest manufacturing technique. It has boosted production efficiency, precision and speed whilst also improving safety and cost-effectiveness.
Principles of CNC and Manual Machining
CNC Machining Principles
Automatic CNC manufacturing method needs digital inputs with tooling and cutting instructions. This method requires several tools to assemble machined parts. CNC machinists create digital tool libraries to work with CNC machines, which can then work independently after having the digital inputs.
Manual Machining Principles
Manual machines, on the other hand, are operated manually by technicians. They use traditional machines, such as drill presses, end mills, bandsaws, grinders and lathes. Using these machines, technicians build a variety of prototyping items, but it requires more time and attention to complete the manufacturing process compared to using the CNC method.
What Are the Benefits of CNC Machining?
Now that you know what CNC manufacturing is, let’s try to understand the benefits offered by CNC machining.
Accuracy and Consistency
CNC machining ensures accuracy and consistency in product quality. The process is more accurate than manual methods, and each resulting product is of the same quality.
Enhanced Production Rate
CNC machining is an automatic process, which leads to more production of items with better efficiency. This method uses computers to control the process, which ultimately enhances the quality and speed of manufacturing.
Safety
The biggest advantage of using CNC machining is that it ensures the safety of the workers. Everything in CNC machining is operated using a computer; thus, it is safer than manually operated machines.
Cost Efficiency
The CNC manufacturing method is cost-efficient. This is because everything in the CNC method is operated through computer programs, and fewer technicians are needed. One worker can operate several machines at the same time, which reduces the cost per worker. On the other hand, in manual machining, one worker is required for each machine.
The Cost Difference Between CNC Machining and Manual Machining
To make an informed decision between CNC machining and manual machining, it is necessary to understand the cost difference between them.
The Overall Cost Is Less Than That of Manual Machining
The manufacturing method’s overall cost is affected by various factors, such as maintenance charge, scrap rate, production of parts and labour costs. In the CNC manufacturing process, all these factors are reduced, which results in less overall cost than manual machining.
Low Scrap and Maintenance Issues
The CNC manufacturing technique is more precise and accurate, thereby producing less scraps as compared to manual methods. Also, the labour cost and maintenance charges are reduced in CNC machining.
More Demand in the Industry
CNC is more in demand as compared to manual methods because of its fewer maintenance charges, waste rate and labour cost. Less accurate parts and more scrap generation have reduced the demand for manual machining methods all over the globe.
