Working Member Chip-Breaking Section for Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Chip removal or unwanted tearing occurs on the front and back sides of workpieces during machining with rotating tools, impairing the optical quality and requiring effective prevention methods.
Innovation Solution
A working element with a contact section and a chip-break protection section that includes a splinter protection section protruding from the contact surface, which can be detachably connected to guide rails or work tables, providing adjustable and interchangeable tear protection to prevent chip removal on all sides of the workpiece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a rubber lip on a guide rail is used to prevent chip removal, then chip removal on one side of the workpiece is prevented, but chip removal on the front or rear side of the workpiece still occurs
Solution Approach 1:
The chip protection function is divided into multiple independent chip protection sections, each protecting a different side of the workpiece. Instead of relying on a single rubber lip on the guide rail, the system uses multiple detachable chip protection sections that can be positioned on different sides of the workpiece to prevent chip removal on all sides independently.
Solution Approach 2:
The chip protection section is designed as a universal component that can protect multiple sides of the workpiece. By making the chip protection section detachable and repositionable, a single component design serves multiple protective functions across different workpiece sides, eliminating the need for side-specific protection devices.
2Object-affected harmful factors
If a fixed chip protection device is used, then chip removal prevention is achieved, but adaptability to different workpiece geometries and machining situations is reduced
Solution Approach 1:
The chip protection section is designed to be detachable and repositionable rather than fixed, allowing dynamic adjustment to different workpiece geometries and machining situations. The clamp connection enables the chip protection section to be moved to different positions along the guide rail or workpiece to adapt to various cutting scenarios.
Solution Approach 2:
The chip protection section is pre-positioned on the guide rail or workpiece before machining begins, allowing it to prevent chip removal on all sides of the workpiece from the outset. The detachable design enables preliminary setup for different workpiece types while maintaining flexibility for adjustments during different machining operations.

AI summary
The invention relates to a working element for use with a workpiece to be machined and an electric machine tool for machining the workpiece, wherein during machining a machining tool of the machine and the workpiece are moved relative to each other in a machining direction, wherein the working element comprises a contact section for the workpiece and a chip-breaking section, in particular connected with the contact section, which prevents chip removal caused by the action of the machining tool on the workpiece at an exit side of the workpiece from which the machining tool exits, wherein the contact section has a contact surface which extends in the machining direction and against which the workpiece rests during machining, and wherein the chip-breaking section projects from the contact surface.
