Embodiment 2

[0099] Corresponding to the above-mentioned embodiment 1, this example will specifically explain the preparation method of the CNC machined part 1 disclosed in embodiment 1, which includes the following steps:

[0100] Machining appearance features 10 on the CNC machined part 1 by a plurality of cutters;

[0101] Among them, the following steps are also included:

[0102] On any XY plane on the CNC machined part 1, the Z-direction positive step feature z2 and the Z-direction negative step feature z1 are processed by each tool; the depth of the Z-direction positive step feature z2 is the positive value of the allowable deviation in the Z direction. The upper limit deviation, the depth of the negative step feature z1 in the Z direction is the negative lower limit deviation of the allowable deviation in the Z direction;

[0103]On two mutually parallel XZ planes on the CNC machined part 1, the Y-direction negative step feature y1 is processed by any tool on the XZ plane on its u...

Abstract

In order to solve the problems that a large amount of manpower, and a large number of tools and detection instruments have to be put into an existing CNC machining part to detect the size precision of the machining part, and then whether the CNC machining part is qualified or not can be judged, the invention provides a CNC machining part and a manufacturing method of the CNC machining part. The CNC machining part comprises appearance features machined through a plurality of cutters, wherein a Z-direction positive step feature, a Z-direction negative step feature, a Y-direction negative step feature, a Y-direction positive step feature, an X-direction negative step feature and an X-direction positive step feature are further machined on the CNC machining part. According to the CNC machining part and the manufacturing method of the CNC machining part, the tools and the instruments are not needed any more, and whether the size of the machining part is qualified or not can be primarily judged through visual contact. The detection efficiency is improved, and the detection cost is saved. Meanwhile, due to the fact that only visual contact is needed in measurement, the tools do not need to make contact with a product, and the probability of appearance defects of a workpiece is greatly reduced.

Description

technical field [0001] The invention relates to the field of CNC machining. Background technique [0002] At present, such as mobile phone casings, notebook casings, tablet casings, etc., are processed by CNC (full name in Chinese: computer numerical control machine tool, full name in English: Computer numerical control). For the convenience of description, these products processed by CNC are collectively referred to as CNC machines. Processing parts, the above-mentioned CNC machined parts are not limited to the above-mentioned mobile phone casings, notebook casings, tablet casings, etc. Any product processed by CNC can be regarded as CNC machined parts. [0003] CNC is an automated machine tool controlled by a program. The control system can logically process the program specified by the control code or other symbolic instructions, and decode it through the computer, so that the machine tool can perform the specified action, and the blank can be processed into semi-finishe...
