Rapid Prototyping is a necessary step in the product development process, the prototypes help validate the appearance and functionality of product before mass production. As one of the Rapid prototyping techniques, CNC Prototyping is widely used in various industries. Today, we will share to you a guide about CNC prototyping technique.

What Is CNC Prototyping?

CNC prototyping is one of rapid prototyping process that use a CNC machine to create a physical model of product before mass production. it uses Cutting tool controlled by computer to cut the workpiece. CNC prototyping can achieve good dimension accuracy of the prototype and make it fast.

Types Of CNC Prototyping Techniques

There are mainly two Types of CNC Prototyping Techniques as below:

CNC Milling

CNC milling machine uses rotated milling cutting tools to cut the solid block of materials to get the desired shape prototypes. the computer controls the speed and movements of the rotated milling tools.

CNC Turning

CNC turning machine Roate the solid block of materials, then use lathe cutting tool to cut the material. lathe cutting tool’s movement is linear without rotating and condoled by computer. this technique is widely used for cylinder prototypes.

Benefits Of Using CNC Prototyping

CNC prototyping is widely used in various industries, because it can bring many benefits as below:

Machining FAST

CNC Prototyping use computer with CAD/CAM design software to control cutting tools can make the ptototypes as mininum as few hours, which is much faster than manual operations as traditional machining method do.

Cost-Effective

for most cases, only one prototype is needed by engineers to validate the design, in this case, CNC prototyping can directly be used for machining the prototype, this can avoid any tooling building and save the tooling cost which is usually high.

Flexibility

CNC prototyping can be used to create complex shape prototypes especially with 5-axis CNC machining, it can cut the workpiece from different angles to form different shapes which will cost too much if use a tooling to make it.

High Accuracy And Precision

CNC machine can achieve high precision due to it is control by computer and high accuracy and small cutting tools. the prototypes make by CNC prototyping can achieve 0.05mm tolerance which is good for most of products.

Material Versatility

CNC prototyping can work on various materials from plastic to metal material. and there are many kinds of plastic and metal sheet, and blocks are manufactured for CNC machining due to this process already used a lot in the market.

CNC Prototyping Vs 3D Prototyping

To compare CNC prototyping with 3D prototyping, we use a table to compare each factor they have as below:

FactorCNC Prototyping3D Prototyping
Working processSubstract manufacturing, cut workpiece to final partsAdditive manufacturing, builds parts layer by layer
Materialsworks with metals, wood, plastics, and alloysLimited to thermoplastic materials
Possible GeometryLimited internal complexitySupports complex internal and external geometries
WastageHigher material wastageLow material wastage, used as needed
Manufacturing TimeSlower than 3D printing, takes hours to create a single piece.Faster, creates parts in minutes
Prototyping CostRelatively expensive due to machine and accessories costs.More cost-effective due to low machine cost
Part ToleranceHigh tolerance level of ±0.01 mm.Slightly lower tolerance of ±0.1 mm
Part strengthCNC parts tend to be strongerweaker than CNC prototyping

CNC Prototyping Vs Rapid Injection Molding

Rapid injection molding prototyping is a traditional way to build large volume prototypes, here we compare CNC prototyping with Rapid injection molding in terms of some factors.

FactorInjection-Molded PrototypesCNC Machined Prototypes
Part Tolerance±0.1 to 0.7mm due to shrinkageVery high tolerance of ±0.01mm
MaterialMostly plastics or elastomersWood, plastic, or metal
Surface QualityMay have minor defects like warping, sink marks, flow lines, etc.Better surface finish
Prototyping CostCheap unit price if a large volume more than 100 piecescheap is volume is low, less than 100
Possible GeometryLimited complexity with tooling structure constraintmore complex, no tooling constraint

Regardless, if you’re unsure about which method to use for your rapid prototypes, feel free to contact Kusla at any time, and we will provide you with a professional and prompt suggestion.
