CNC (Computer Numerical Control) machining is an automated process that involves using
a machine to remove material from raw stock based on computer-generated instructions.
It is applicable to a wide range of materials, from expanded polyurethane foam to nickel superalloys.
Common applications for CNC machining include manufacturing, crafting ornamental furniture, and
producing turbine blades.
The cost of CNC machining is influenced by factors such as precision requirements, surface finish,
quantity, material selection, and the complexity of the part being produced.

FAQ's
1. What Are the Advantages of Using a CNC Machine?
CNC machines offer numerous advantages in the manufacturing industry.
They can operate with minimal operator intervention and have the potential to run continuously, 24/7,
especially when integrated with robotic systems for loading and unloading.
CNC machines provide consistent and repeatable accuracy, ensuring minimal dimensional variations
between thousands of produced parts.
Additionally, CNC machines are capable of creating intricate and complex features that would be
challenging to achieve with manual machines.
2. What Are the Applications of CNC Machining?
CNC machining is a versatile process employed across a wide range of materials, each with its own
ideal machining parameters, including speeds and feeds.
Here are some of the most common materials used:
1. Metals
Metals are the most frequently machined materials, ranging from easily workable brass to robust
nickel superalloys like Inconel.
CNC machining in metal finds application in various industries, including the production of injection
molds, shafts, and gears.
2. Plastics
While injection molding is the primary method for plastic part production, CNC machining is utilized
for specific plastic components.
Common plastic materials include ABS (acrylonitrile butadiene styrene), nylon, and polycarbonate.
Plastic CNC machining is suitable for valve bodies, bushings, and prototypes to assess part functionality
before investing in costly molds.
3. Wood
CNC routers are commonly employed for wood cutting, offering a cost-effective alternative to
metal-cutting CNC machines.
Wood CNC machining is often used for decorative purposes, such as crafting furniture, window frames,
and ornamental panels.
4. Foam
Polyurethane foam, both closed-cell and open-cell varieties, is frequently used in CNC machining
applications.
CNC routers can shape foam blocks to create custom packaging for high-value items, such as
toolboxes designed to securely transport tools.
5. Composites
CNC machines play a crucial role in processing composite materials like aramid, fiberglass, and
carbon fiber.
These abrasive materials require precise machining to add fastener holes and trim components
in industries like aerospace and marine manufacturing.
