This Week's Issue: Minimizing Tearout in Wood Projects
Are you frustrated with rough edges and splintering when cutting wood on your CNC? Tearout can be a real project-ruiner, but fear not! We've got some tips to help you achieve clean, crisp cuts.
Key Strategies:
- Use sharp, high-quality bits
- Make sure to use the correct up/down/compression flutes
- Optimize your feed rate and spindle speed
- Consider climb cutting for finish passes
- Use sacrificial backing boards
- Apply tape to the cutting area
Pro Tip:
For intricate designs or text, try a two-stage cutting process. First, use a larger bit to rough out the shape, leaving a small amount of material. Then, switch to a smaller bit for a finishing pass. This method can significantly reduce tearout and improve overall quality.

📖CNC Term of the Week📖
Chip Load
Definition: Chip load refers to the amount of material removed by each cutting edge of a tool as it rotates. It's typically measured in inches per tooth (IPT) or millimeters per tooth (MMT).
Why it matters:
- Affects tool life and cutting efficiency
- Influences surface finish quality
- Impacts heat generation during cutting
Calculating Feed Rate:
Chip Load = Feed Rate / (RPM × Number of Flutes)
Not sure what all of those mean?
- Feed Rate: Speed at which the tool moves through the material
- RPM: Rotational speed of the tool
- Number of Flutes: The number of cutting edges on your tool
Tip: Different materials and tools have optimal chip load ranges. Consult manufacturer recommendations and experiment carefully to find the sweet spot for your specific applications.
