Precision CNC Machining: Guidelines for Part Tolerancing

When it comes to CNC machining, proper tolerancing is key to ensuring your machined part matches up closely with your design intent. Without proper tolerancing in place, you risk costly delays and rework due to out-of-tolerance components.

Read this guide to learn more about applying tolerances in your CNC machining design. Inside we explore:

• The different types of tolerances used in CNC machining and what geometric aspects of the part they control
• When and where these various tolerances should be used
• How do datums and the LMC/MMC of your part impact your tolerancing
