A Concise Guide to CNC Machining Parameters

Many of the crucial machining parameters are established by the machine operator during the

generation of G-code.

Among the primary parameters we will discuss are the CNC machine's build size and its precision.

CNC machines are equipped with a relatively spacious build area, particularly when compared to

3D printers.

CNC milling systems are capable of machining parts with dimensions of up to

2,000 x 800 x 100 mm (78” x 32” x 40”), while CNC turning systems excel at machining parts with

diameters reaching up to Ø 500 mm (Ø 20’’).

CNC machining empowers the creation of components with exceptional accuracy and stringent

tolerances. These machines are capable of achieving tolerances even finer than half the diameter

of an average human hair, with a precision of ± 0.025 mm or .001’’.

In cases where tolerances are not explicitly specified in the technical drawings, operators typically

machine the part with an accuracy of 0.125 mm (.005’’).

CNC machining parts with geometric complexity: what are the design restrictions?

While CNC machining offers remarkable design flexibility, it is essential to recognize that not all

geometries can be readily manufactured using turning and milling machines.

Unlike 3D printing, where complexity does not necessarily equate to increased costs, CNC

machining follows a different paradigm.

In this context, the greater the design complexity, the higher the machining costs due to the

additional steps involved.

The primary constraints associated with CNC machining revolve around the geometry of each

specific cutting tool.

The tool's geometry determines the radii of a part, and most CNC cutting tools exhibit cylindrical

shapes with limited cutting lengths. Consequently, achieving sharp internal corners poses a

significant challenge.

Tool access represents another pivotal limitation in CNC machining. For instance, 3-axis systems

are constrained in terms of part complexity since all features must be accessible directly from

above.

In contrast, 5-axis systems offer superior flexibility by allowing adjustments in the angle between

the part and the tool, enabling access to otherwise challenging areas on the workpiece.

Moreover, CNC machines encounter difficulties when handling parts with thin walls or delicate

features. Thin walls are susceptible to vibrations and may fracture under the forces exerted during

turning or milling.

As a guideline, it is advisable to design metal parts with a minimum wall thickness of 0.8 mm and

plastic parts with a wall thickness of 1.5 mm.

Comprehending the degree of complexity feasible for various machine types and being aware of

these constraints is crucial to ensuring that your designed parts are successfully produced to meet

your desired quality standards.
