CNC drilling and milling ↓∏  machines are typically capable of movi©←±ng cutting tools and/or workpieces εγalong several different axes of ±≈<$motion.

1. CNC stands for "Computer ​α✘Numerical Control".

CNC machining is a type of "α<machining that is widely us©<ed in manufacturing applications, b<♠ut what exactly does it do tδ¶'≈o achieve the various actions of a CNC×÷  drilling and milling machine CNC ma®↕chining can be used to€≥ machine parts made of man ∏y different materials, such asε☆≤↑ a variety of metals and plastic•÷s, etc. 2.

2. CNC drilling and milling machines a★ • re programmed using a language called G☆>-code.

CNC machining uses special CNC softwa​∑♥πre and a programming language↕Ω§  called G-code in order $∑₽to control all aspects of the movement ₽>£"of the CNC drilling and ♥§$ milling machine in order t€∞αφo create an object that is machined o♠↔πn demand. the G-code commands cλ δontrol the speed and position ofπ✔↑≥ the cutting tool with re↑λspect to the workpiece, the fe"↕γσed rate of the material to‌&σ the tool, and many other factor←₽★s.

3. It all starts with CAD
　　
The process usually ←∑σ±starts with a 2D CAD (Co•‍↕mputer Aided Design) drawing or 3D CA ☆★D model. G-code is then de←​rived from this and an air test progra‍<≈ mme is carried out. This is called &qu¶ ×βot;cutting air" >σ ♠and is used to avoid irreversible situa× ↓tions that could lea±±∑βd to damage to the workpiece or €$cutting tool. If the tes"≤∑t is satisfactory, th≈​₹e programme can be run to act on the pa♣λ↑ rt to be machined. 4.

4. CNC drilling and milling machin®♥πes provide accuracy and repeatabil $ity

CNC drilling and milling machines c​∞☆an be used to make comφ∞♥plex three-dimensional shΩ£™apes as individual part↕ δ↓s. It offers higher accuracy than m→✘✘anual machining. Most im₩↓γportantly, it is repeatab<σle. The same set of CNσ>β∞C programmes can be used time and time π again to make the samγφ↑e batch of parts.

5. Use CNC to make any part you ∞₽can imagine!

CNC drilling and mil↔>✘ling machines are typ★ <ically capable of moving cu≥&•♦tting tools and/or workpieces al ααong several different λ£≈≈axes of motion. 3-axis CNC drilling© β← and milling machines can move in th¥¶e X, Y, and Z axes to produce a three-d≈≤•&imensional shape, which is the basi↕ σ×c model. More advanced 4-axis CNC mach∑¥ines introduce a 4th axis of rotar☆φy motion parallel to the X-axis, allo₹∑↔¶wing more complex objec↓ α☆ts to be produced. It is also possib↓↓α le to use 5 or even 6-axis mac<>hines that can produce almost any↔$ shape imaginable.
