Precision Machining VS Conventional Machining

Machining is a process that is used to shape a raw material into a desired form using different cutting tools. When it comes to machining, two broad categories come into play; precision machining and conventional machining. In this post, we will look into the differences and similarities of these two categories. So, let’s jump right into it!

What is Precision Machining?

As the name suggests, precision machining is a technique that is used to create intricate designs with fine accuracy. It involves the use of Computer Numerical Control (CNC) machines which operate using a set of pre-programmed software codes. These codes guide the machines on how to move the cutting tools to achieve the desired shape and design.

What is Conventional Machining?

Conversely, conventional machining is a manual process that involves the utilization of hands-on machines such as lathes, drill presses, and milling machines. The operator manually controls the movement of the tools in the direction of the desired shape.

Precision vs Conventional Machining: The Differences

1. Accuracy and Precision: Precision machining is known for its accuracy and precision, with tolerances as low as 0.0001 inches, something that conventional machining cannot achieve.
2. Production Time: Precision machining, with its CNC machines and pre-programmed codes, produces results at a faster pace as compared to conventional machining.
3. Production Volume: When it comes to mass production of parts, precision machining is more suitable as it can produce thousands of parts at a faster rate.
4. Equipment Cost: Precision machining requires sophisticated CNC machines which come at a considerable cost as compared to the conventional types of equipment.

Precision vs Conventional Machining: The Similarities

1. Both techniques require the use of cutting tools, including drills, lathes, milling machines, and saws.
2. They produce the desired shapes of the workpiece with refinement and minimal wastage.
3. Both require skilled personnel to operate the machines.

In conclusion, the choice of using precision machining or conventional machining depends on the specific requirements of the project. For projects that require a high degree of accuracy and intricacy, precision machining is the way to go. However, when it comes to projects that require the production of simple shapes, conventional machining is a more suitable option.
