![]() ![]() Artists regularly use it to produce artwork, and fashion designers use it to create their apparel and jewelry.ģD printing has some exotic applications, as well. The food industry has also made use of this technology, producing foods by squeezing them out layer by layer. Invented at MIT in the late 1980s, it found its first uses in prototyping, but its applications have since expanded into a variety of fields.ģD printing and additive manufacturing are of great use in the medical field, where they can create organs, prosthetics and implants. Overview of 3D PrintingģD printing is the popular name for additive manufacturing, which refers to building products from the bottom up, adding one layer at a time. Most new CNC machines are completely electronic. CNC machines may combine various tools into single “cells” to maximize efficiency. Laser cutters , which are powerful cutting tools good for cutting metal, plastic and woodĬNC machines often involve the use of multiple tools, such as drills and saws, to make the needed cuts.Plasma cutters , which use a plasma torch to cut two-dimensional shapes into sheet metal.Routers , which cut large-scale components from wood, plastic and sheet metal.Drills , which use a spinning drill to carve stationary material. ![]() Grinders , which cut using an abrasive wheel.Lathes , which rotate the material on a spindle.Mills , which use rotary cutting tools to sculpt components.Stepper or servo motors ensure the movements will be precise. Some of the more basic machines move along three axes, while more advanced machines have four or five axes. This process typically begins with a block of material, which an array of rotating tools and sharp blades cut away. Once the instructions are created, a post-processing program converts them to specific commands and transfers them to the CNC machine for execution. The CAD file then gets translated into instructions using a computer-aided manufacturing (CAM) program. Learn About Our CNC Machining Services How It Worksįirst, an engineer makes a 2D or 3D model using CAD, or computer-aided softwar e. It is common in industries such as woodworking, lettering and engraving. It tends to be best for engines, airplane machinery and other fields where robust parts are needed. For this reason, you will also hear people call it traditional manufacturing.ĬNC machining can produce parts that are strong and have precise dimensions. ![]() ![]() MIT introduced this technology in the 1950 s, and it has since become a staple of the manufacturing industry. Overview of CNC MachiningĬomputer numerical control (CNC) is a common type of subtractive manufacturing, meaning it carves out needed components from large blocks of material. Although both processes are standard today, each has evolved to meet different demands - so it’s important to know which method will best suit your needs. When you want to create a new part, there are two manufacturing methods you can turn to: CNC machining and 3D printin g.
