What is CNC?
CNC (Computer Numerical Control) machining is a subtractive manufacturing technology: parts are created by removing material from a solid block (called the blank or workpiece) using a variety of cutting tools. Let’s see the benefits of outsourcing CNC machining services.
This is a fundamentally different way of producing compared to additive (3D printing) or formative (injection molding) technologies. The material removal mechanisms have a significant impact on the advantages, limitations, and design limitations of CNC. More about this is below.
Types of CNC Machining
CNC machining is a manufacturing process suitable for a wide range of industries including automotive, aerospace, construction and agriculture, and capable of producing a range of products such as automotive frames, surgical equipment, aircraft engines, gears and hand and garden tools. tools. The process involves various computerized operations, including mechanical, chemical, electrical, and thermal processes, which remove the necessary material from the workpiece to produce a custom-designed part or product. While chemical, electrical, and thermal machining processes are covered in a later section, this section examines some of the most common CNC machining operations, including:
- Drilling
- Milling
- Turning services
Digital production technology for companies
CNC machining services is a digital manufacturing technology: it produces high-precision parts with excellent physical properties directly from a CAD file. Due to the high degree of automation, CNC is price competitive for both one-off custom parts and medium-sized productions.
Almost any material can be CNC milled. The most common examples are metals (aluminum and steel alloys, brass, etc.) and plastics (ABS, Delrin, Nylon, etc.). Foam, composites and wood can also be processed.
The basic CNC process can be divided into 3 steps. The engineer first designs the CAD model of the part. The operator then converts the CAD file into a CNC program (G code) and sets up the machine. Finally, the CNC system performs all operations with little supervision, removes material and creates the part.
