Why CNC Machining Prototype
CNC stands for computer numerical control
machining is a manufacturing process that used in a wide range of industries
for both prototype and end product. In CNC process, machining tools like drills
and lathes are controlled by computer inputs. CNC machining process begins with
a digital 3D design which is done through CAD software. Computer can translate
them into instructions to machine’s cutting tools. When the instructions are
sent to the machines, machines will cut and run the machining automatically. So,
there is very few manual operation needed. Compared to traditional machining,
CNC machining is time and cost saving significantly. Unlike 3D print, machining
is a process that equipment removes existing material instead of adding new
materials. More complex part with more intricate geometries could be cut by
complex CNC machines with greater number of axes. CNC machining is an
attractive manufacturing process because it is versatile, accurate and
consistent. Numerous metal and plastics can be used for machining.
CNC machining is an important process when
it comes to prototype parts making. The most basic function of prototypes is
they act as a model to show the visual information and the look of final
products. They are also used to act as a new product to show potential
customers. Although prototypes are important, but they do not need to be made
using high level or expensive equipment, they could be done by hand or 3D
printer. When function prototypes require strength and mechanical stability
that are not afforded by additive manufacturing method, CNC machining prototype is an ideal choices because of its production speed, part quality and material
options.
The biggest advantage of CNC Machining is
that it is an automatic process building parts from computer files. Machined
prototypes match the digital design very closely. Repeatability is high. 3D
design allows quick and precise changes. For example, if a machined prototype
has errors, engineer can go back to the CAD software to make suitable changes
for next prototypes. Prototypes in different options can be compared side by
side, and can be test the how the parts will be in the real world.
Except for the advantages, CNC machining
prototyping has limitations. For example, CNC machining is more expensive than
3D printing. It has some geometrical restrictions and it create material waste.
