Few techniques in the theory and practice of CNC machining have had the same impact on my work life as those described in the article below. Continue reading and your life could be changed as well.
CNC machining is a process that has literally changed my work life for the better on my journey through the worlds of prototyping, welding, and machining. CNC has become ubiquitous for businesses and utilities that want to implement or provide a cheaper way to produce parts and components because it is easier to do and harder to master.
CNC machining is a method of performing tasks such as drilling, boring, and cutting under the control of a machine. CNC machines use computer files to create a set of instructions and specifications, which they then use to refine and cut a piece of metal into a finished product. It's a simple, repeatable, and efficient model that employs CNC controllers to make complex cuts that would take too long to complete manually.
CNC (Computer Numerical Controlled) machining is a careful process that has many advantages over conventional methods and procedures, and we'll look at a few inherent techniques that changed my life in this article.
Ironically, clamping a workpiece securely onto a spinning plate or mandrel was the first computer procedure in history. The cutting tool is held against the workpiece in a fixture mounted on a rotating slide as it turns. As required, the slide can be pushed up and down the length of the workpiece to get closer to or further away from the center line. This straightforward action is perfect for rapidly extracting large quantities of waste. A drill bit mounted on the tailstock may also bore specific holes down the workpiece's centerline. This is a subtractive technique that is almost exclusively used on metal work.
Electrical Discharge Machining (EDM) or Solid Sink EDM
A conductive electrode is positioned next to the workpiece when bathed in a dielectric fluid, not to be confused with the music genre of the same name. The electrode is custom-made for the function it's cutting. Metal particles are forced off the workpiece's surface with each electrode discharge. Although the electrode does not come into contact with the workpiece, it is a sacrificial component that will need to be replaced on a regular basis. This is the method's only drawback.
EDM is used to create pockets, holes, and square features within hardened tool steels that would be difficult, if not impossible, to achieve any other way. It's most often used on molds for plastic injection and pressure die casting, but it's rarely seen on the finished product. On mold tools, EDM is often used to produce textured surfaces or debossed (recessed) lettering and logos.
This method is endorsed by many experts and reputable CNC machining services. It is one of the most common and well-liked methods, especially in the use case for which it is designed.
CNC machining is extremely useful when creating specialty optics. Thin surfaces and tight tolerances are required in optics. You can spin and grind a wheel against a surface with the aid of grinding equipment. This aids in the elimination of nominal variations. Grinding paste may also be used to lubricate the machine. This paste also gives the surface a polished look.
To summarize, the techniques mentioned above made my work life easier and helped me to produce high-quality work at a faster pace. Since then, I've had happy customers and even happier employees.
