The CNC machining process, standing for computer numerical control machining, is a subtractive
manufacturing approach that utilizes a synergy of computerized controls and machine tools to
eliminate layers from a solid block of material. Programming dictates the desired cuts in the metal,
aligning them with specific tools and machinery, and the automated process executes the
machining task accordingly.
Product Details
The choice of raw material directly impacts machining costs.
Different materials have varying costs, availability, and machining characteristics.
High-performance alloys may be more expensive than common metals.

FAQ's
1. What size of fillets are added when no specific fillet is specified by the 3D model
or drawing?
When no specific fillet radius is outlined in the 3D model or drawing, the machinist will
incorporate fillet radii at their discretion to optimize for easy machining.
In instances where a particular fillet radius is needed, explicit specification is encouraged.
As a rule of thumb, consider internal vertical edge radii exceeding 1/3 of the depth, while
internal horizontal edges may either remain sharp or be introduced with a radius ranging from
0.5mm to 1mm.
