How do I choose the right shape for my insert?

Dec. 14th, 2023
When it comes to inserts, choosing the right geometry is crucial to achieving optimum performance in a variety of applications. Whether using cutting tools, moulds or other industrial processes, insert geometry plays an important role in determining the efficiency and effectiveness of the operation. This guide discusses the key factors to consider when selecting the appropriate insert geometry.

1. Material Compatibility

Different materials exhibit unique properties and the choice of insert shape should be matched to these properties. For softer materials such as aluminium and plastics, a sharp insert shape with a sharp cutting edge may be preferred. In contrast, harder materials such as stainless steel and titanium may require inserts with stronger, reinforced geometry to withstand increased cutting resistance. Consider the hardness, wearability and thermal conductivity of the material to ensure that the insert geometry can effectively cope with the specific challenges posed by the material.

2. Cutting Conditions

Cutting conditions such as speed, feed rate and depth of cut have a direct influence on insert performance. High-speed cutting operations benefit from inserts with geometries designed to dissipate heat efficiently and prevent premature wear. In heavy cutting applications, inserts with robust geometry and enhanced cutting edge strength become essential. By understanding the cutting environment, insert geometries can be selected that maximise tool life and minimise the risk of tool failure.

3. Application Type

Specific insert geometries are required for different machining operations to achieve optimum results. For turning applications, triangular or diamond-shaped inserts with multiple cutting edges and versatility may be preferred. For end-face machining, square inserts with a wide cutting face may be advantageous. Milling operations may require different insert geometries to meet specific cutting requirements, depending on whether front or profile milling is used.

4. Geometry Considerations

Insert geometry includes various features such as rake angle, relief angle and edge finish. The rake angle affects cutting efficiency, while the clearance angle affects chip evacuation. Cutting edge preparation, such as the presence or absence of a chamfer or polished edge, influences overall cutting performance. Understanding these geometric factors allows you to fine-tune your selection based on the specific requirements of your application.

5. Toolholder Compatibility

Insert geometry and toolholder compatibility are critical to stability and performance. Different toolholders are designed to accommodate specific insert geometries and sizes. Ensuring an exact fit is essential to prevent vibration, tool deflection and even insert ejection during machining. Check the toolholder specifications and select an insert geometry that integrates seamlessly with the holder to increase the stability and accuracy of the machining process.

6. Cost Efficiency

While performance is a top priority, cost efficiency must also be considered in practice. Evaluate the balance between the initial cost of the insert and its expected lifetime. Depending on the shape of the insert, tool life may be extended, resulting in less frequent replacements and consequently lower overall costs. Budget constraints are analysed and compared with the anticipated benefits of different insert geometries to balance performance and affordability.

In conclusion, the process of selecting a suitable insert geometry requires a careful analysis of various factors. Material compatibility, cutting conditions, type of application, insert geometry, toolholder compatibility and cost efficiency can help to make informed decisions, optimise tool performance, improve productivity and contribute to the overall efficiency of the machining process. Keep abreast of technological advances, as ongoing innovations may introduce new insert geometries that further improve and tailor performance to specific applications.
