Some CNC machines, such as the CNC mill, may leave visible tool marks. Because of this, an additional step may be required or recommended to finish the part. There are many different finishing options depending on your project requirements. Talk to a Fathom expert to see which is the best option for your job.
Whatever your question, I assure you, we’ve heard it before. Here are some common CNC machining questions we receive. Any other questions, please contact our machine shop today for answers.
Q / / What language is used by CNC machines?
A / / CNC machines are primarily programmed using G-code though M-code is also acceptable.
Q / / Are CNC and VMC the same?
A / / No. A computer controls CNC machines. A VMC is a kind of CNC machine used to cut metal.
Q / / Why should I use CNC machining?
A / / Since the process is automated, it increases efficiency, lowers costs and increases accuracy.
Q / / What materials can be used in CNC machining?
A / / Depending on the application, common materials include stainless steel, copper, brass, aluminum, titanium, foam, polypropylene, ABS, POM, PC, Nylon and more.
Q / / What are the five different CNC machines?
A / / CNC lathe machine, router machine, milling machine, laser cutting machine and plasma cutting machine.
Q / / What is the difference between DNC and CNC?
A / / A direct numerical control (DNC) system uses a mainframe computer to operate multiple machines. DNC refers to the networking of more than one CNC machine.
Q / / What industries use CNC machining?
A / / Aerospace, medical device, photonics, defense, electronics, transportation and more.
Q / / What type of finish is produced by CNC machining?
A / / Some CNC machines, such as the CNC mill, may leave visible tool marks. Because of this, an additional step may be required or recommended to finish the part.
Q / / What are the standard finishes for CNC parts?
A / / Bead blast, anodized, chem film, passivation, powder coat, electropolishing, electroless nickel plating, silver plating and gold plating are all standard options.
Computer Numerical Control (CNC) machining is a manufacturing process during which a pre-programmed computer software directs the movement of factory machinery and tools. CNC machining can control a variety of complex machinery, from mills and routers to grinders and lathes. Using CNC machining allows three-dimensional cutting tasks to be accomplished with a single set of prompts. This process has become popular because there is no need for a live operator to push levers, buttons or wheels. Once a CNC machine has been activated, the cuts are programmed into the software and then communicated to the tools and machinery which perform the task, similar to a robot.
CNC machining is ideal for projects requiring production-grade materials and rapid prototyping of tight tolerance plastic and metal parts with excellent surface finishes. The repeatability of the process also opens up the possibility of producing high volume manufacturing of parts using CNC machining.
