Choosing Between CNC and Manual Milling Machining for Your Projects

The development of computer numerical control (CNC) machining has lead to changes in the machining industry. When you require complex parts or machinery, you now have the option of choosing either CNC or manual machining.

Advantages of CNC Milling

CNC machines use computerised control over various machining and milling tools for complex projects. The data is often prepared using CAD (computer-aided design) software and entered in the machine. Computerising the machining process brings several significant advantages including speed and accuracy.

CNC milling may provide faster turnaround for the completion of your project. There are fewer manual steps involved in CNC milling compared to manual milling. Depending on the project, CNC machining may also require fewer tools to complete the same job.

The accuracy of cutting with CNC milling is improved compared to manual methods. Computers are not prone to the same mistakes as humans. If the design is properly programmed into the software, there is little risk of mistakes.

Advantages of Manual Milling

You should also consider the pros and cons of manual milling machining in Perth. While CNC machining offers several useful advantages, there are also several benefits to conventional machining.

With manual milling, a skilled machinist manually cuts the pattern that you require. For smaller projects, this often results in lower costs. You may also avoid waiting for the availability of CNC machines. In some shops, the CNC machines are steadily booked on other projects, resulting in a longer wait time.

While manual milling is still the preferred choice for most smaller projects, there are a few potential issues. The process may take slightly longer compared to using CNC machines. There is also a greater risk of mistakes and wasted material.

How to Select the Best Machining Method

The process you choose depends on the details of your specific project. If you need to manufacture a high volume of parts or require a complex cutting job, CNC milling may provide the right solution. CNC machining is typically a faster process and produces less waste due to the accuracy of computer-controlled tools.

This does not mean that you cannot use CNC machining for small projects. In fact, skilled machinists should have no problem manufacturing an individual part using a CNC machine. However, this may cost more than manual milling.

If you need to manufacture a small number of parts, you may find manual milling to be more cost-effective. Experienced machinists can still handle complex projects using manual milling and give each part a superior attention to detail.

Before you get started on your next project, remember the pros and cons of both CNC and manual milling. Talk to an experienced machinist to learn more about your options and discuss the details of your project.
