Designing text for CNC machining
October 24
When it comes to adding text and logos onto the surface of your part designed for CNC machining there are a few things to keep in mind. Starting with, for text and logos, engraved text is better than embossed text as this means less material is removed. Choosing engraved over embossed will safe you both time and money.
Text size should be at least 5mm high, 0.8mm deep and there should be at least 0.5mm clearance between letters. Following these guidelines will help with the legibility and visual impact of your machined text.
Sans Serif style font of 20 point is recommended as many CNC machines have routines already programmed for these fonts.
Follow this design tip and other tips coming up to achieve a part design that is well suited for CNC machining. Below is some further CNC machining guidance which may help you with designing a successful part for CNC machining.
HLH Max CNC Machining Size: 3000x1200x850mm
Advantages
High speed
High dimensional accuracy
Great surface finish
Wide material selection
High volumes
Rapid prototypes
Drawbacks
It can be expensive for complex
parts and for larger parts.
Tolerances: ISO 2768-1 states the tightest tolerances possible as standard are +/- 0.05mm for metals or +/- 0.2mm for plastics. Tighter tolerances should be discussed case by case.
