Solution Overview

Problem

Existing methods for producing toothings on workpieces require high mechanical engineering outlay and are not efficient in terms of productivity and cycle time.

Innovation Solution

The method involves simultaneous or parallel processing of reworking toothings on one end face while generating toothings on the other end face, using tools that can operate independently in time, allowing for immediate continuation of processing on the second end face after completing reworking on the first, and utilizing deburring and chamfering tools to remove burrs concurrently with the gearing process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional sequential methods are used for producing toothings with deburring and chamfering, then manufacturing precision is improved, but productivity is reduced and cycle time increases

Engineering Contradiction:
Improvequality of toothingsVSAvoidproduction efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The invention applies preliminary action by performing deburring and chamfering operations simultaneously with the toothing generation process rather than sequentially. Multiple tools (toothing tool, deburring tool, and chamfering tool) operate concurrently on the workpiece, with deburring removing material in advance of chamfering, thereby eliminating waiting time and improving productivity while maintaining quality

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention implements continuity of useful action by ensuring that all tools (toothing, deburring, and chamfering) operate continuously and simultaneously throughout the entire toothing generation process. The tools are positioned and synchronized so that useful work is performed at all times without idle periods, maximizing productivity while maintaining manufacturing precision through coordinated tool operations

Inventive Principle:
Principle #20Continuity of useful action

2Productivity

If multiple tools are used for simultaneous toothing, deburring, and chamfering operations, then productivity is improved and cycle time is reduced, but device complexity increases

Engineering Contradiction:
Improveproduction efficiencyVSAvoidmachine tool complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The invention merges multiple functions (toothing generation, deburring, and chamfering) into a single integrated machine tool setup. Multiple tools are mounted on the same machine and operate simultaneously on the workpiece, combining several manufacturing operations that would traditionally require separate machines or sequential processes, thereby improving productivity without proportionally increasing device complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The machine tool is designed with multi-functionality, capable of performing toothing generation, deburring, and chamfering operations with different tools mounted on the same device. This universal capability allows a single machine to replace multiple specialized machines, improving productivity while keeping device complexity manageable through standardized tooling and positioning mechanisms

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Device complexity

If sequential processing is used for toothing generation and post-processing, then device complexity is reduced, but loss of time increases and productivity decreases

Engineering Contradiction:
Improvemachine tool simplicityVSAvoidcycle time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The invention applies preliminary action by positioning and preparing multiple tools (deburring and chamfering) in advance on the same machine tool, so they can operate simultaneously with the toothing generation process. This eliminates the time loss associated with moving workpieces between machines or repositioning tools sequentially, reducing cycle time while maintaining manageable device complexity through coordinated tool setup

Inventive Principle:
Principle #10Preliminary action

AI summary

In a method for producing toothed sections on workpieces, a toothed section is firstly produced by means of a first tool in the region of a first end face of a workpiece to be toothed. The produced toothed section is reworked on the peripheral face by means of at least one second tool in the region of the first end face, while the toothed section is further produced. If the toothed section is also produced in the region of the second end face by means of the first tool, the reworking in the region of the first end face is already completed, so the toothed section can also be reworked in the region of the second end face. Short cycle times are thereby achieved with a low machine-related outlay.
