CNC VS Manual Machining, Which One Is Suitable For You?

DALIAN, China - April 23, 2023 - PRLog -- CNC machining (https://www.sansmachining.com/) has become the core pillar of modern manufacturing technology. Most industries rely on this technology to handle the needs of multiple production stages. From prototype production to batch production, CNC processing can be done. CNC machining or computer numerical control has become a faster and more efficient manufacturing strategy.

The manual processing shall be operated manually by experienced or well-trained machinists. Through the final comparison between CNC machining and manual machining, the advantages of CNC machining seem limitless.

However, some manufacturers rely on manual processing tools to produce prototype parts. In particular, manual processing plays a prominent role in the industry and in small batch rapid prototyping.

This article will give a side-by-side overview of these two technologies and understand their performance on each important parameter.

CNC And Manual Machining Principle

CNC Machining Principle

CNC machining is a manufacturing process in which the cutting tool is controlled by an automatic system to remove material from the workpiece. This is an extensible process that can complete all work from prototype production to mass production.

Automatic CNC machining requires digital files with cutting and machining instructions. Therefore, the CNC machine process needs various tools to manufacture machined parts, and engineers and machinists build a digital tool library to interact with the CNC machine.

These machines can be operated automatically by applying digital instructions and design startup in CAD software (computer-aided design). The 3D model created by the software determines the attributes and dimensions required for the final part.

Because the CAD-CAM software package is bundled with some of the software programs, the production can continue in the same program. If CAD and CAM software manufacture the same product family, no document translation is required. Otherwise, you need to import the CAD file.

Manual Machining Principle

The tool in this process can be simple or complex, but the relative motion is completed by the operator.

Manual machines are controlled by hand, including any traditional machines, such as band saws, drilling machines, grinders, end mills and lathes. Using these manual machines, mechanics can create a large number of prototype projects for various purposes. However, compared with CNC processing controlled by automation or computer, manual processing requires more time and more attention to perform any function.
