Basic Information About CNC Precision Machining

By Jeffrey Walker


Machining is used by manufacturers in creating parts made from metal usually but also with composites, ceramic, plastic and wood for different products. They cut the raw material into a certain shape and size with the process of controlled material removal or subtractive manufacturing. These use machine tools and not just power or hand tools.

This is done with the help of digital instructions from computer programs that can translate CAM and CAD files. It would then be translated by the CNC precision machining and create what was designed with these software applications. This makes the cutting process automated resulting to an improved speed and accuracy when creating the prototype parts.

These processes need the use of multiple tools for making your desired cuts like having drill bits with various sizes. Machines combine tools usually with the basic ones could move in a couple of axes while the advanced ones can do so longitudinally, rotationally and laterally. The latter has the capability of automatically rotating the parts which allows the removal of those underside ones.

Doing this will make flipping stock materials by workers manually an unnecessary task because it lets each side be automatically cut. Compared to the manual inputs, usually, these are more accurate but sometimes the finishing is better when done by hand. Etching is included in this and those simpler cuts that extensive programing work is needed for them.

There are two categories for these machines, novel and conventional technologies, with the latter using milling machines, drills and lathes. Drills will have the drill bits spinning while moving to make contact with that block while lathes have the block spin instead until it and the cutting tool touches each other. Milling ones are common and use rotary tools for cutting.

Novel technologies use specialized techniques like ultrasonic, photochemical, electrical discharge, electrochemical and electron beam machining. Most of them are intended for special cases in producing mass quantity which a particular material type is involved. Other mediums for cutting in this technology includes water jet, plasma, oxy fuel and laser.

Using these machines will increase efficiency in manufacturing parts because of the aforementioned improved speed and accuracy. You would also need to hire less workers which can still accomplish more due to these devices. Cost of manufacturing is greatly reduced also because human error is removed but instead you will have precise parts made.

Some also have automatic assembly features that removes manual assembly which allows companies to take larger or more projects because of reduced production time. Waste of these highly expensive materials is also reduced which could save the business some money. They can now utilize effectively all materials without wasting most parts of it which usually happens when an error is done during production.

Ways on how to boost efficiency, increase productivity and increase bottom line are what companies look for which makes them sought after precision machining. These are compared usually with 3D printing as they contemplate which could better do the job they need. This depends on economic factors, complexity and available materials, and 3D printing is capable of complex shapes although it can only use limited materials.
