Solution Overview
Problem
Existing laser profile cutting machines struggle to maintain precision during inclined cutting operations on flexible profiles due to varying projection lengths, leading to asymmetrical geometry and increased bending deformation, especially when creating flared holes.
Innovation Solution
The machine and method involve positioning the support and guide device in a starting position relative to the working head and moving it integrally with the feeding device to maintain a constant projection length during the cutting operation, compensating for tilting movements to ensure consistent bending and symmetrical geometry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the support and guide device is kept stationary during inclined cutting operation, then the working head can be inclined to perform chamfering or flared hole operations, but the profile projects to a variable extent from the support and guide device causing bending deformation and asymmetrical geometry
Solution Approach 1:
The support and guide device is transformed from a stationary component to a dynamic one that can move along the longitudinal axis. During inclined cutting operations, the support and guide device moves integrally with the feeding device to maintain a constant projection length of the profile, thereby keeping bending deformation constant and ensuring symmetrical geometry while still allowing the working head to be inclined for chamfering or flared hole operations.
2Adaptability or versatility
If the projection length of the profile from the support and guide device varies during working, then the working head can be inclined for different operations, but the bending deformation of the profile varies leading to asymmetrical results
Solution Approach 1:
The system implements a feedback mechanism where the position of the support and guide device is continuously adjusted based on the position of the working head and the feeding device. During inclined cutting operations, the support and guide device moves to maintain a constant projection length, effectively compensating for the inclination of the working head and ensuring consistent bending deformation and symmetrical geometry throughout the operation.
3Manufacturing precision
If the support and guide device is moved integrally with the feeding device, then the projection length remains constant and bending deformation is consistent, but the device complexity increases
Solution Approach 1:
The support and guide device is merged with the feeding device in terms of motion control. Both devices move integrally along the longitudinal axis, sharing a common drive mechanism. This combination allows the support and guide device to maintain a constant projection length of the profile during inclined cutting operations without requiring a completely independent complex positioning system, thereby achieving precision while controlling device complexity.

AI summary
A machine and method for laser working of profiles and in particular for carrying out an inclined cutting operation on profiles are provided. Before working operation, a support and guide device are positioned in a given starting position along the longitudinal axis of the profile with respect to a working head. During working operation, the support and guide device are moved along the longitudinal axis integrally with a feeding device, that is with the profile, so as to keep constant the extent of the projection of the profile from the support and guide device. Integral movement of the support and guide device with the feeding device is limited to the portion of the movement of the feeding device which is required to compensate for tilting movements of the working head about an axis of oscillation.
