Manhart How to consider the factor of workpiece material when adjusting the parameters of CNC punching machine?

When adjusting the parameters of a CNC punching machine, the material of the workpiece is a very important factor to consider. Different materials have different characteristics such as hardness, toughness, and cutting performance, which directly affect the processing efficiency and quality of punching. The following are specific considerations when adjusting parameters based on workpiece material factors:
1、 Hardness of workpiece material
Workpieces with high hardness (such as high-speed steel, titanium alloys, etc.) require the selection of tool materials with good wear resistance to extend tool life. At the same time, it may be necessary to reduce the cutting speed and feed rate to avoid adverse effects of excessively high cutting temperatures on the workpiece.
For workpieces with lower hardness, the cutting speed and feed rate can be appropriately increased to improve machining efficiency. But also be careful not to cut too fast, so as not to cause a decrease in the quality of the workpiece surface.
2、 The toughness of the workpiece material
Workpieces with good toughness are prone to plastic deformation during the punching process, so it may be necessary to increase the depth of the punch to ensure the depth and accuracy of the punching.
2. At the same time, for workpieces with good toughness, the punching speed should be appropriately reduced to avoid deformation or tool damage caused by excessive impact.
3、 Cutting performance of workpiece material
1. The cutting performance of different materials varies, and appropriate cutting parameters need to be selected based on the specific material. For example, soft materials such as aluminum alloy have good cutting performance, and the cutting speed and feed rate can be appropriately increased; However, hard alloys and other difficult to machine materials have poor cutting performance and require lower cutting and feed rates.
When selecting cutting parameters, you can also refer to some specific numerical information. For example, depending on the material, there may be a rough recommended range for cutting speed. For difficult to machine materials such as hard alloys, it is usually recommended to control the cutting speed at a lower level, such as between tens to hundreds of revolutions per minute; For soft materials such as aluminum alloys, the cutting speed can be appropriately increased, such as between several hundred to several thousand revolutions per minute.
4、 Thickness of workpiece material
The thickness of the workpiece is also an important factor affecting parameter adjustment. For thicker workpieces, it may be necessary to increase the depth of punch pressing and cutting depth to ensure the depth and accuracy of punching.
2. At the same time, attention should also be paid to adjusting the punching speed and feed speed to adapt to workpieces of different thicknesses. Thicker workpieces may require lower punching and feed speeds to avoid deformation or tool damage caused by excessive impact.
In summary, when adjusting the parameters of CNC punching machines, the factors of workpiece material should be fully considered. By selecting appropriate tool materials, adjusting cutting parameters, controlling punching speed and feed rate, etc., machining efficiency can be improved while ensuring machining quality.
