Manhart How to adjust the machining parameters of a twisted axis CNC bending machine based on the material properties of the workpiece?

Adjusting the machining parameters of the torsion axis CNC bending machine based on the material properties of the workpiece is an important step in ensuring machining accuracy and workpiece quality. The following are the specific steps and considerations for parameter adjustment based on the material properties of the workpiece:
###1、 Understand the material properties of the workpiece
Firstly, it is necessary to have a detailed understanding of the physical and mechanical properties of the workpiece material to be processed, including but not limited to:
*Elastic modulus: reflects the ability of a material to resist elastic deformation.
*Tensile strength: The maximum force that a material can withstand during the stretching process.
*Yield strength: The stress value at which a material begins to undergo plastic deformation.
*Resilience: The ability of a material to absorb energy without fracture when subjected to impact or load.
*Hardness: The ability of a material to resist local deformation, especially indentation or scratches.
These performance parameters will directly affect the deformation behavior, rebound degree, and susceptibility to cracking or fracture of the workpiece during the bending process.
###2、 Select and adjust processing parameters
It is crucial to choose appropriate machining parameters based on the properties of the workpiece material. Here are some key processing parameters and their adjustment methods:
1. * * Bending force**
-Adjustment principle: Choose the appropriate bending force based on the yield strength and tensile strength of the material. Harder materials require greater bending force, while materials with lower toughness require appropriate reduction of bending force.
-Adjustment method: Set appropriate bending force parameters through the pressure control device of the CNC system. During the trial machining process, gradually adjust the bending force until the best machining effect is found.
2. Bending angle**
-Adjustment principle: Determine the bending angle according to the product design requirements and consider the rebound phenomenon of the material during the bending process. Some materials may require preset larger bending angles to compensate for rebound.
-Adjustment method: Use the angle adjustment device of the CNC system to accurately set the bending angle. During the trial machining process, observe the rebound of the workpiece and make adjustments accordingly.
3. * * Bending speed**
-Adjustment principle: For harder materials, the bending speed can be appropriately accelerated to improve production efficiency, but attention should be paid to avoiding excessive speed that may cause increased tool or mold wear; For materials with poor toughness or easy deformation, the bending speed should be appropriately slowed down to ensure machining accuracy and workpiece quality.
-Adjustment method: Set appropriate bending speed parameters through the speed control device of the CNC system. During the trial machining process, make appropriate adjustments based on the deformation of the workpiece and the machining efficiency.
4. * * Mold selection and adjustment**
-Mold selection: Choose the appropriate mold based on the hardness, shape, and bending angle of the workpiece material. The accuracy and wear resistance of molds have a significant impact on machining quality.
-Mold adjustment: Ensure accurate and stable installation of the mold on the bending machine. Adjust parameters such as spacing, angle, and inclination of the mold according to the shape of the workpiece and bending requirements.
###3、 Trial processing and verification
1. * * Trial processing * *: Before formal processing, conduct trial processing to verify the rationality and effectiveness of the selected processing parameters. Observe the deformation, surface quality, and whether there are cracks or fractures during the bending process of the workpiece.
2. * * Parameter adjustment and optimization * *: Based on the trial processing results, make necessary adjustments and optimizations to the processing parameters. Through multiple attempts at processing and fine-tuning, until the optimal combination of processing parameters is found.
###4、 Precautions
1. * * Safe operation * *: When adjusting processing parameters and conducting trial processing, it is necessary to comply with safety operating procedures to ensure the safety of personnel and equipment.
2. * * Equipment Maintenance * *: Regularly maintain and upkeep the torsion axis CNC bending machine, check the wear and deformation of each component, and replace damaged parts in a timely manner.
3. * * Recording and Feedback * *: Record the parameter settings and processing results of each processing for subsequent analysis and improvement. At the same time, provide timely feedback on any problems and difficulties encountered during the machining process in order to obtain technical support and assistance.
By following the above steps and methods, the machining parameters of the torsion axis CNC bending machine can be adjusted reasonably according to the material properties of the workpiece, thereby ensuring that the machining accuracy and workpiece quality meet the design requirements.
