Navigating the Challenges of Interrupted Cuts

By Grindmasters Inc. Staff | Updated on Apr. 13, 2024

In the world of machining, few things are as complex and challenging as interrupted cuts. These are situations where the cutting tool intermittently loses contact with the workpiece, creating a series of unique challenges that can impact the efficiency and quality of the machining process.

Imagine driving on a road filled with potholes. The constant jarring and unevenness is not just uncomfortable; it also puts additional strain on your vehicle. Similarly, interrupted cuts can cause increased wear and tear on cutting tools, lead to poor surface finishes, and create unwanted vibrations.

But like any challenge, it's manageable. With a comprehensive understanding of the phenomenon and a strategic approach, navigating the rough road of interrupted cuts and ensuring a smooth machining process is possible.

This article aims to shed light on the intricacies of interrupted cuts, exploring their causes, the problems they present, and the strategies to overcome these challenges. We'll delve into the technical aspects and keep it accessible for those new to the topic.

The Basics of Interrupted Cuts

Interrupted cuts are a fundamental aspect of machining that every professional in the field must understand. They occur when the cutting tool intermittently loses contact with the workpiece, creating a discontinuous cutting process. This contrasts with continuous cuts, where the tool remains in constant contact with the workpiece.

This intermittent contact typically happens when machining irregular surfaces, keyways, or grooves. For instance, when turning a workpiece with a keyway, the tool will cut through the material, pass over the keyway (losing contact), and resume cutting. This stop-start nature of the cutting process is what characterizes interrupted cuts.

Interrupted cuts are not limited to any specific operation and can occur in various machining processes, including turning, milling, and grinding. In turning, they often happen when the workpiece has an irregular shape or features like grooves or slots. In milling, interrupted cuts can occur when machining workpieces with cavities or when slot milling. In grinding, interrupted cuts can occur when grinding gear teeth or other interrupted surfaces.

Interrupted cuts present a common challenge in machining as they can significantly impact the efficiency and quality of the processes. The intermittent contact can cause fluctuations in cutting forces, leading to tool vibrations. These vibrations can, in turn, affect the tool life and the quality of the surface finish.

The Challenges

Interrupted cuts, while typical in machining, present a unique set of challenges that can significantly impact the efficiency and quality of the machining process. These challenges primarily stem from the intermittent contact between the cutting tool and the workpiece, which can lead to increased tool wear, poor surface finishes, and unwanted vibrations.

Increased tool wear is a significant concern in interrupted cuts. The cutting tool is subjected to shocks entering and exiting the workpiece. This repeated impact can cause the tool to wear out faster, reducing its lifespan and potentially affecting the quality of the cut. Moreover, the irregular contact can lead to inconsistent heat distribution, further accelerating tool wear.

Poor surface finishes are another common issue with interrupted cuts. The intermittent contact and the resulting vibrations can lead to irregularities on the machined surface. This can be particularly problematic in precision machining, where maintaining a high-quality surface finish is crucial.

Vibrations, as mentioned, are a significant challenge in interrupted cuts. The stop-start nature of the cutting process can lead to tool chatter, a form of vibration that can affect the stability of the machining process. This can result in dimensional inaccuracies in the machined part and contribute to poor surface finish and increased tool wear.

Heat variations also play a role in the challenges posed by interrupted cuts. The intermittent contact means the heat generated during the cutting process must be consistently distributed. This can lead to thermal shock to the cutting tool, further accelerating tool wear and potentially affecting the structural integrity of the workpiece.

Finally, the cutting speed can significantly influence the tool life and the surface finish. A high cutting speed can lead to excessive heat generation and rapid tool wear, while too low a speed can result in a poor surface finish. Therefore, finding the optimal cutting speed is an essential aspect of managing interrupted cuts.

Overcoming the Challenges

Addressing the challenges posed by interrupted cuts is a multifaceted task that requires a strategic approach. This involves careful selection of tool materials, adjustments in cutting parameters and using appropriate coolants. Let's break these down:

Selection of Tool Materials:

The choice of tool material is crucial in managing the wear and tear caused by interrupted cuts. Materials that can withstand the shock and heat variations associated with interrupted cuts are preferred. For instance, carbide tools, known for their hardness and heat resistance, are often used in such situations. Recent advances have also introduced ceramics and cubic boron nitride (CBN), offering even greater hardness and heat resistance.

Adjustments in Cutting Parameters:

The cutting parameters, including cutting speed, feed rate, and depth of cut, play a significant role in managing the challenges of interrupted cuts. Adjusting these parameters can help control the heat generated and the forces experienced by the tool, thereby reducing tool wear and improving surface finish. For instance, reducing the cutting speed can help manage heat generation, while adjusting the feed rate and depth of the cut can help control the cutting forces.

Use of Appropriate Coolants:

Coolants serve two primary purposes in machining: they help manage the heat generated during the cutting process and lubricate the contact between the tool and the workpiece. In the context of interrupted cuts, using appropriate coolants can help mitigate the heat variations and reduce the thermal shock experienced by the tool.

Leveraging Advanced Technology:

Recent advances in machining technology have provided new ways to manage the challenges of interrupted cuts. For instance, advanced tool materials with greater hardness and heat resistance can help reduce tool wear. Similarly, modern tool path planning techniques can help manage cutting forces and vibrations, improving surface finish and dimensional accuracy.

Tool Geometry and Cutting Edge Radius:

The geometry of the cutting tool and the cutting edge radius also play a crucial role in managing interrupted cuts. A larger cutting-edge radius can help distribute the cutting forces over a larger area, reducing the impact of the forces and thereby reducing tool wear and vibrations.

By strategically addressing these aspects, effectively managing the challenges posed by interrupted cuts is possible. This not only ensures a smoother and more efficient machining process but also improves the quality of the machined parts, leading to better overall productivity and cost-effectiveness.

Real-life Examples

In the machining industry, practical experience often speaks louder than theory. Several companies and machinists have successfully navigated challenging interrupted cut situations, providing valuable case studies that underscore the importance of strategic planning and execution.

Aerospace Industry:

In the aerospace industry, interrupted cuts are common when machining components like turbine blades, which have complex geometries and materials that are difficult to cut. Companies have successfully managed these challenges by using advanced tool materials like ceramics and CBN and optimizing their cutting parameters. For instance, a high-speed, low-feed approach has effectively reduced tool wear and improved surface finish.

Automotive Industry:

In the automotive industry, interrupted cuts often occur when machining engine blocks with numerous cavities. By using carbide tools with a large cutting-edge radius and applying appropriate coolants, companies have reduced tool wear and achieved a high-quality surface finish.

Oil and Gas Industry:

The oil and gas industry presents unique challenges for interrupted cuts, particularly in drilling operations. Drilling through layers of rock and sediment involves constant interruptions, and the drill bits used in these operations are subjected to extreme conditions. Companies have managed these challenges by using drill bits made of superhard materials like diamond and carefully controlling the drilling parameters. Additionally, using drilling mud, a coolant helps manage the heat and lubricate the drill bit, reducing wear and tear.

Manufacturing Industry:

In manufacturing, interrupted cuts are common when machining large workpieces with irregular shapes or performing operations like slot milling. By using robust tool materials, optimizing cutting parameters, and leveraging advanced tool path planning techniques, companies have managed the challenges of interrupted cuts and improved their machining efficiency.

These examples underscore the importance of a strategic approach to managing interrupted cuts.
