Solution Overview

Problem

Current machine tools lack the capability to perform extensive machining options on workpieces with optimized quality and minimized time expenditure, as they often require multiple clamping positions and tool changes for different machining processes.

Innovation Solution

A machine tool design that allows relative movement between the tool spindle and workpiece carrier, enabling oscillating lifting movements and transverse adjustments via a displaceable rod, which can be coupled to a motor device for precise positioning and adjustment of cutting tools, allowing for combined machining processes like fine boring and honing without changing the clamping position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple clamping positions and tool changes are used for different machining processes, then machining versatility is improved, but machining time and complexity increase

Engineering Contradiction:
Improvemachining versatilityVSAvoidmachining time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The machine tool is designed with a universal workpiece carrier that can accommodate multiple machining processes (turning, drilling, milling, threading) in a single clamping position. The carrier includes integrated tool holders and positioning mechanisms that enable different operations without requiring workpiece removal or repositioning, thus eliminating time loss while maintaining versatility

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

Solution Approach 2:

Multiple machining functions are merged into a single integrated workpiece carrier system. The carrier combines turning tools, drilling apparatus, milling mechanisms, and threading devices in one unified structure, allowing all these operations to be performed on the workpiece without changing clamping positions or performing tool changes, thereby reducing total machining time

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple clamping positions are used for different machining processes, then machining versatility is improved, but device complexity increases

Engineering Contradiction:
Improvemachining versatilityVSAvoidclamping system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single universal workpiece carrier is designed to perform multiple machining operations through integrated mechanisms rather than requiring multiple specialized clamping devices. The carrier includes adjustable tool holders, positioning systems, and cutting mechanisms that can be reconfigured for different operations, providing versatility while maintaining a unified, manageable system structure

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

Solution Approach 2:

The workpiece carrier incorporates dynamic, adjustable components that can be repositioned and reconfigured for different machining operations. Tool holders can be moved to various positions, cutting tools can be adjusted, and the carrier itself can be reoriented, providing the versatility of multiple clamping positions through a single dynamic system rather than multiple static devices

Inventive Principle:
Principle #15Dynamics
