The Details Of Precision Machining


Precision Machining is a process where the physical property of a material is altered while maintaining a high level of accuracy. It involves performing a mechanical process on a given material to change its physical properties. This level of accuracy generally depends on the type of machine used. It can be classified into Milling and Turning machines.

The most common machines used are the numerically controlled (NC) machines and the computer numerically controlled (CNC) machines. Numerically controlled machines require the use of actual coordinates to control the position of the cutting head, speed of the spindle and the feed rate of the cutter. A punch card or tape is used in this type of machine.

The computer numeric control machine is one whereby all stages of the process is done by computer which is programmed to produce the required shapes and curves that can be represented as a formula. The desired cut shape is programmed as a series of splines that are translated into position coordinates which are then fed to the machine.

Whereas conventional machining involves automatic or manhandled machines, computer numeric controlled machining and Precision Machining is done through programming. It utilizes technology and automation to produce precise designs and generate quality output. It is very accurate and gives one the unique opportunity to repeat work and hence meet the specification of the design.

Computer numerical control provides a flexible and versatile control over the tools in use as well as the creation of complex geometry designs. One can select the best speeds and feeds to the lathes and drills. This provides for optimum life span of the tools and the required rates of production

As expected with all machine processes, waste is an inevitable byproduct of your work. The amount of waste generated depends on the material, the machine used and the specific process. Typically, for a metal cutting operation, expect small bits of metal removed from the larger work piece. Lubrication and cutting fluids also require proper disposal.
