Abstract

The invention discloses a CNC (computer numerical control) machining tool setting and marking process, which comprises the following steps of: providing a workpiece to be processed; performing CNC machining on the workpiece, and machining a tool setting mark in a non-appearance requirement area of the workpiece by using a tool after the workpiece completes machining of all structural features; and checking the workpiece which is subjected to CNC machining, wherein if the non-appearance requirement area of the workpiece has complete tool setting marks, the tool is intact, and if the non-appearance requirement area of the workpiece has no tool setting marks or has incomplete tool setting marks, the tool is damaged. According to the CNC machining tool setting stamp process, after a workpiece is machined on all structural features, a tool is used for machining in a non-appearance requirement area of the workpiece to form a tool setting stamp, and whether the tool is damaged or not can be judged by checking whether the tool setting stamp in the non-appearance requirement area of the workpiece completely exists or not. Compared with the traditional method, the CNC machining tool setting print process is time-saving and labor-saving, and the CNC machining efficiency can be improved.

Description

CNC machining and knife printing process

technical field

The invention relates to the field of processing the middle plate or the bottom plate of mobile terminal equipment, in particular to a CNC machining and knife-marking process.

Background technique

Currently, CNC (Computernumerical control, computer numerical control machine tool) is usually used to complete the preparation and processing of the middle plate or bottom plate of mobile terminal equipment (eg, mobile phone, tablet computer). The CNC machine tool control system logically processes the program specified by the control code or other symbolic instructions, and decodes it through the computer, so that the CNC machine tool can perform the specified action, and the blank is processed into the finished workpiece by tool cutting.

During the CNC machining process of the middle plate or bottom plate of mobile terminal equipment (for example, mobile phone, tablet computer), the tools with small diameter on the CNC machine are prone to damage (broken, chipped, etc.), and manual inspection of the turret is required. Whether the tool or product structure feature is complete, to check whether the tool is damaged. This method is time-consuming and labor-intensive, thereby reducing the efficiency of CNC machining, and checking the turret tool is dangerous.

detailed description

In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.

The CNC processing of an embodiment as shown in Figure 1 is to the knife printing process, comprises the following steps:

S10 , providing a workpiece to be processed.

The workpiece can be a middle board or a bottom board of a mobile terminal device.

The workpiece is usually processed by CNC, and the blank is processed by tool cutting, and the tool with a small diameter on the CNC machine is prone to damage.

S20. Carry out CNC machining on the workpiece obtained in S10, and use a tool to process the non-appearance requirement area of the workpiece to form a tool mark after all the structural features of the workpiece are processed.

Generally speaking, the diameter of the tool that needs to be added to the tool mark operation does not exceed 4mm. Tools with a diameter of no more than 4mm are more prone to damage after processing due to their fragile structure.

Although tools with a diameter of more than 4mm are not easy to be damaged after normal processing, it is also possible to increase the tool mark operation for tools with a diameter of more than 4mm to avoid timely detection of tool damage caused by misoperation.

Preferably, the processing depth of the knife mark is 0.4mm-1.2mm. The processing depth of the knife marks is 0.4mm~1.2mm. On the one hand, it can avoid the reduction or damage of the mechanical strength of the workpiece caused by too deep processing. judge.

Specifically, the operation of using a tool to process a non-appearance-required area of the workpiece to form a tool mark is: using the tool to process a scratch along one direction on the non-appearance-required area of the workpiece to form a tool mark. At this time, the shape of the knife mark is a rectangle or a straight line.

Preferably, the length of the knife mark is 1mm-5mm. The length of the tool mark is 1 mm to 5 mm. On the one hand, it can avoid the appearance of the workpiece being affected by too long processing, and on the other hand, it can also avoid the low visibility caused by the formed too short tool mark, which affects the judgment.

S30. Check the CNC-processed workpiece obtained in S20. If the non-appearance requirement area of the workpiece has complete tool setting marks, the tool is in good condition. If the non-appearance requirement area of the workpiece has no tool setting marks or incomplete tool setting print, the tool will be damaged.

Specifically, if the non-appearance requirement area of the workpiece has a complete tool alignment mark, the tool is in good condition; if there is no tool alignment mark in the non-appearance requirement area of the workpiece, the tool is broken; If the knife is marked, the knife will collapse.

This kind of CNC machining tool mark process, after all the structural features of the workpiece are processed, the tool is used to process the tool mark in the non-appearance requirement area of the workpiece. By checking whether the tool mark in the non-appearance requirement area of the workpiece exists completely, it can be judged Whether the tool is damaged. Compared with the traditional method of manually checking whether the turret tool or product structure features are complete, this CNC machining saves time and effort for the knife printing process, and can improve the efficiency of CNC machining.

The above-mentioned embodiments only express several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but should not be construed as limiting the patent scope of the present invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention should be based on the appended claims.
