Machine Tool Damper Orientation for Multi-Direction Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machine tools with vibration dampers oriented parallel to side faces are ineffective in damping vibrations not parallel to these faces, leading to suboptimal performance.
Innovation Solution
The machine tool features first and second vibration dampers oriented at a right angle to the travel direction, allowing them to decouple and effectively dampen vibrations in directions neither parallel to the side faces, with the option to be active or passive and adjustable through additional elements and drives for precise orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If vibration dampers are oriented parallel to side faces, then the structure is simple and manufacturing is easy, but vibrations in directions not parallel to side faces cannot be effectively damped
Solution Approach 1:
The patent introduces a new orientation dimension for vibration dampers, positioning them perpendicular to the travel direction rather than parallel to side faces. This dimensional change enables the dampers to address vibrations in previously uncovered directions, specifically diagonal vibrations that occur neither parallel to the first nor second side faces, thereby resolving the contradiction between manufacturing simplicity and vibration direction coverage.
Solution Approach 2:
The patent employs asymmetric orientation of vibration dampers relative to the machine tool's side faces. By orienting dampers perpendicular to the travel direction rather than parallel to side faces, the system creates an asymmetric configuration that specifically targets diagonal vibration components. This asymmetric arrangement allows effective damping of vibrations in directions that would be missed by symmetric, side-face-parallel orientations.
2Adaptability or versatility
If vibration dampers are oriented perpendicular to travel direction, then vibrations in multiple directions can be damped, but device complexity increases
Solution Approach 1:
The patent makes the vibration damper system universal by enabling it to handle multiple vibration directions through perpendicular orientation. The dampers configured perpendicular to the travel direction can simultaneously address vibrations along the first side face, second side face, and diagonal directions, making the damping system multi-functional and adaptable to various vibration scenarios without requiring separate dampers for each direction.
Solution Approach 2:
The patent introduces dynamic adjustability to the vibration damper orientation system. By making at least one damper adjustable in its orientation, the system can adapt to different vibration patterns and machine tool configurations. This dynamic capability allows the dampers to maintain optimal effectiveness across various operating conditions while managing the inherent complexity through controlled adjustability rather than fixed complex arrangements.

AI summary
A machine tool includes a first machine element movable in a travel direction and having first and second side faces. The first and second side faces of the first machine element run parallel to the travel direction and are oriented at a right angle to each other. The first machine element is moved in the travel direction in a guideway of a second machine element by a drive unit in a positionally controlled manner. The machine tool further includes first and second vibration dampers which are oriented at a right angle to the travel direction and configured to dampen vibrations of the first machine element in respective vibration directions. At least one of the first and second vibration dampers is oriented to solely dampen a vibration in a vibration direction that is neither parallel to the first side face nor parallel to the second side face.
