Embodiment Construction

[0022] To pre-process the groove of the workpiece, first analyze whether the workpiece conforms to this method. The specific method is: 1. Analyze whether the processed part is a through groove. If it is not a through groove, this method is not applicable. 2. After the maximum edge of the workpiece processing part expands outward by 1.5 times the diameter of the tool, if there are still residues, this method can be used.

[0023] If do not conform to processing with conventional method, if conform to adopt the method of the present invention to process, specifically as follows:

[0024] refer to Figure 7 , a groove segmentation processing method, the method comprises the following steps:

[0025] Step 1. Make the auxiliary surface in the PowerMill software programming environment. The distance between the auxiliary surface and the workpiece is 1.3 times the tool diameter; specifically: use the PowerMill software to model, and use the boundary function to expand the maximum e...

Abstract

The invention belongs to the technical field of processing, and in particular relates to a segmented processing method for grooves. The method comprises the following steps: Step 1, making an auxiliary surface under the programming environment of PowerMil software; Step 2, utilizing contour finishing for reciprocating tool feeding; Step 3, utilizing contour finishing for unidirectional up-milling edge finishing; Step 4 1. Generate a processing program through steps 2 and 3; step 5, use the processing program to process the workpiece. The invention is a segmented processing method for concave through grooves, which solves the shortage of processing such parts in existing factories, avoids processing accidents caused by residual thin-walled rolls on the cutter, doubles the work efficiency, and improves the processing efficiency. The remaining materials can also be used to make some small parts, which maximizes the value of materials.

Description

technical field [0001] The invention belongs to the technical field of processing, and in particular relates to a segmented processing method for grooves. Background technique [0002] Many factories mainly produce die casting and metal moulds. There are many kinds of parts in the mold, and the plate parts are mainly responsible for supporting, linking and other functions. The part blank is usually a plate, after milling, planing, grinding and other processes, the final part is finished by CNC finishing. When through grooves are encountered in the machining of plate parts, area removal strategies are often used to remove excess material (see Figure 6 ), this method is time-consuming, and when the tool is processed quickly, the strength of the material is reduced, causing the thin wall at the bottom to be involved in the tool, causing the tool to break, the workpiece to be deformed, the accuracy of the machine tool to be reduced, and the workpiece to be scrapped seriously. ...
