In recent years, a lot of processing, applied to industry, brought us a lot of possibilities and convenience, so where are these possibilities and convenience? Dongguan precision parts processing is also a glance, then Dongguan precision parts processing possibilities and convenience where? Let's get to the bottom of this.

What is the technical performance of fine parts? Fine parts processing process touch very wide, in this only from the possibility of processing and lunch to analyze two aspects. It is mainly that the size data on the parts processing pattern should be in line with the programming lunch line, and the conditions for the geometric elements that constitute the outline of the parts should be abundant.

(1) The method of dimension marking on the parts drawing shall conform to the characteristics of the NC machining on the fine parts processing drawing, and the dimension shall be quoted at the same reference or directly given the coordinate size.

1, this annotation method is not only easy to program, but also facilitate the mutual harmonic between sizes, in adhering to the design benchmarks, process benchmarks, detection benchmarks and programming origin setting of the divergence of great convenience.

Due to the fact that part designers often think more about the application characteristics such as assembly in size marking, they have to adopt partially scattered labeling methods, which will bring many inconveniences to the process layout and NC machining.

3, due to the high precision of fine parts processing and repeated positioning accuracy, it will not destroy the application characteristics due to the large accumulation error, so the partial scattered marking method can be changed to the same reference size or directly give the coordinate size marking method.

(2) Calculate base points or node coordinates when programming manually. In auto-programming, fine parts processing stops defining all the geometric elements that make up the outline of the part. Therefore, when analyzing the part diagram, it is necessary to analyze whether the given conditions of geometric elements are abundant.

For example, the arc and the straight line, the arc and the arc are tangent on the pattern, but according to the size given on the figure, when calculating the tangent condition, it becomes a intersecting or detached state. Due to the insufficiency of the geometric elements that make up the fine parts, it is impossible to start programming. In this case, the part designer should be consulted.
