Interrupted cutting is an important concept in the field of metal machining, involving cutting operations carried out in an intermittent manner. This method is significant for improving cutting efficiency, extending tool life, and processing difficult-to-machine materials.
What is Interrupted Cutting?
Interrupted cutting is a machining method where the tool does not maintain continuous contact with the workpiece, but instead makes intermittent contact at a certain rhythm. This method is commonly used in operations such as gear machining, drilling, and milling.
Why Use Interrupted Cutting?
Reasons for using interrupted cutting include reducing tool wear, increasing cutting speed, and decreasing heat accumulation during the machining process, thereby improving machining precision and workpiece quality.
What are the Applications of Interrupted Cutting?
- Gear Machining: By making intermittent contact, tool wear is effectively reduced, extending its service life.
- Drilling and Milling: Particularly suitable for processing deep holes or hard materials, helps in chip removal and reducing heat generation during machining.
- Processing Complex Shapes: For machining some special shapes, interrupted cutting offers more flexibility, avoiding continuous friction between the tool and the workpiece.
What are the Advantages of Interrupted Cutting?
- Extended Tool Life: Reduces continuous friction between the tool and material, thereby lowering wear rate.
- Improved Machining Efficiency: Through optimized cutting parameters, machining can be completed in a shorter amount of time.
- Enhanced Workpiece Quality: Reduces heat accumulation during machining, thereby lowering the risk of workpiece deformation.
