CNC Design Guidelines FAQ
Q1: What is the minimum wall thickness for CNC machining?
A: Recommended minimum wall thickness is 0.8mm–1.2mm for metal parts and 1.5mm+ for plastic parts to avoid deformation.
Q2: Why do CNC internal corners have radius?
A: CNC cutting tools are cylindrical, so internal right angles cannot be achieved. Radius transition is necessary for feasible machining.
Q3: What are the limitations of deep hole machining?
A: Excessively narrow and deep holes are difficult to machine. We provide professional structural optimization suggestions.
Q4: What design mistakes should be avoided in CNC parts?
A: Avoid ultra-thin walls, sharp internal angles, extremely narrow grooves and unreasonable tight tolerances to reduce cost and defects.
Q5: How to reduce CNC machining cost?
A: Optimize wall thickness, relax unnecessary tight tolerances, standardize holes and avoid complex redundant structures.
