Introduction

In this tutorial, we will explore the essentials of CNC turning insert nomenclature. Understanding how to read and select turning inserts is crucial for maximizing efficiency in machining operations. This guide will break down the meaning of each component in the insert nomenclature, the different types of inserts, and tips on selecting the right insert for your projects.

Step 1: Understanding Insert Nomenclature

Learn how to read the nomenclature of turning inserts, which typically follows a format like CNMG 12 04 08. Each part of this code provides specific information about the insert.

• Insert Shape: The first letter(s) indicate the insert shape (e.g., CN for a rhombic shape).
• Insert Size: The first number (12) denotes the insert size in millimeters.
• Insert Thickness: The second number (04) represents the thickness of the insert.
• Nose Radius: The last number (08) indicates the nose radius.

Step 2: Types of Inserts and Their Angles

Different inserts are designed for various applications and come with specific angles. Familiarize yourself with the common types and their corresponding angles.

• CCMT: Rhomboid shape with an 80-degree angle, ideal for finishing tasks.
• DCMT: Diamond shape with a 55-degree angle, suitable for general turning.
• VCMT or VBMT: Diamond shape with a 35-degree angle, useful for both finishing and roughing.

Step 3: Selecting the Correct Turning Insert

Choosing the right turning insert can significantly impact the quality of your work. Follow these guidelines:

• Geometry Selection:

  • Base your choice on the operation (e.g., finishing vs. roughing).
  • Use larger nose angles for improved strength and economy.

• Insert Size:

  • Select according to the depth of cut required for your project.

• Nose Radius:

  • Opt for the largest possible nose radius to enhance insert durability.

Step 4: Understanding Chip Breakers

Chip breakers are features on inserts that help manage chip formation during cutting. These can improve surface finish and reduce cutting forces.

• Functionality: Helps control chip size and direction.
• Selection: Choose based on material and machining conditions.

Step 5: Overview of Insert Tools

Familiarize yourself with the various types of inserts and their applications:

• Turning Inserts: Commonly used for external and internal turning operations.
• Insert Shapes: Various shapes (e.g., round, square) cater to different machining needs.
• Carbide Inserts: Known for their hardness, making them suitable for high-speed cutting.

Conclusion

Mastering CNC turning insert nomenclature is essential for effective machining. Understanding the components of the nomenclature, the types of inserts, and how to select the right tool can lead to better performance and outcomes in your projects.
