In the bending processing of the bending machine, with the current technology, the problem is how to reduce the preparation time before the actual processing, especially when the product needs to be processed repeatedly. For processing, in addition to confirming the drawings, it is also necessary to consider the processing mold, the bending sequence of the workpiece, and the program input.
However, these factors must be considered when the actual processing is carried out. There should be no omissions and it takes a long time. If next time you encounter the same workpiece and need to repeat processing, you cannot effectively call the last processing programming information, you can only reprogram, and repeat the same work, which is also called “two repetitive operations”. In this case, it is time And labor waste, repeated consumption, resulting in a decline in the processing efficiency of the bending machine. Therefore, in order to avoid this situation and to better improve the processing efficiency of the bending machine, the processing information of the product can be combined to make, store, and use, and carry out a virtuous cycle to solve the above problems. . And through this mode, the processing program and data can be made available. Flexible application at any time avoids repetitive work and improves the actual processing mode.
If a square shoulder milling cutter is used for rough milling of the mold of the bending machine, the step of removing the stepped cutting allowance should be included in the semi-finishing process. It will change the cutting force and cause the bending of the bending machine to further affect Subsequent finishing affects the geometric accuracy of the mold. Changing to triangular or diamond inserts will produce greater radial cutting force. But if you use a round blade milling cutter, it is completely different. During milling, the transition between adjacent tool paths is smooth, the runout is small, leaving a more uniform machining allowance for subsequent processing, and the cutting thickness is variable, The feed rate is higher. Especially in 5-axis cutting, this insert is particularly suitable without any restrictions.
For the successful milling of hardened die steel, the important application parameters are: depth of the cut, clamping system, and bending machine die. It can be said that these three points are crucial.
