In the machining industry, CNC (computer numerical control) and manual machining both exist. CNC is a computerised machine that performs precise cuts by using automatic tools, which can perform large-scale jobs at a low cost with high efficiency. Manual machining involves the use of various tools to cut materials in a traditional way. However, manual machining has limitations, such as a high cost and low efficiency when compared to CNC. Read on for our comparison between the two…
Why CNC Machining?
CNC machining is a computer-controlled process, which means that our machines can be more accurate than traditional methods. Traditional machining relies on the skills and experience of the operator to control their machine and make adjustments as needed. The result is that you may get parts that are not as precise or consistent in quality from one part to another, or even from one batch to another. In contrast, at Advanced Engineering, our CNC machines produce parts with great precision and repeatability because they use software programmes that calculate exactly how much material needs to be removed at any given time, during each cutting operation based on information provided by an engineering drawing or CAD file (computer-aided design).
CNC Machining VS Manual Machining
Cost
Traditional machining – Traditional machining can be costly, even for small jobs. This is because it requires a lot of manual labour from skilled workers.
CNC Machining – Machining with a CNC machine can be expensive for small jobs but is generally more efficient and cost effective for jobs requiring a number of the exact same part.
Production
Machining in the traditional sense – The final product’s quality is largely determined by the machine technician’s or operator’s skills and abilities.
Machining with a CNC machine – Geometry is loaded into the software, reducing the risk of human error in the quality equation. At Advanced Engineering, we have consistently invested in the latest machinery to support this.
Replication
Machining conventionally – Because it is difficult to ensure high levels of part consistency due to the human factor, conventional machining is best suited for small runs or single pieces.
CNC machining is ideal for large quantities of highly consistent products because machines operate on computer commands.
Experience and abilities
Conventional Machining with a Large CNC Lathe and Milling Machine – Operator experience at Advanced Engineering has a significant impact on part quality and consistency.
Workforce Requirements
Machining in the traditional sense entails a dedicated operator for each machine, and the tools necessitate a high level of technician involvement. Operators must be able to produce a wide variety of parts, which requires extensive knowledge, skills, and experience.
Machining with a CNC machine – Because the CNC process requires little operator involvement, a single operator can supervise multiple machines at the same time with high degrees of accuracy and precision, lowering labour costs.
In most cases, CNC machining is the preferred manufacturing method due to improved product quality, highly consistent production replication, and lower labour demands.
