entities in the mold processing technology bubble in the real application
Weifang Die Since 1997, the introduction of plant design software UG started at the beginning of the study design of three-dimensional entities. Weifang mold factory in 2005 the design of three-dimensional entities with real three-dimensional mold processing technology have been effectively combined with the application, a partial solution to the mold design applications of three-dimensional entities, the problems existing in the mold to reduce the manufacturing cycle, reduced the cost of mold.
Bubble real crux of the whole process of NC programming, process quality largely determines the quality and appearance of mold. I plant the whole process of programming the basic idea is cutting layered entity, flip processing. The first step is to get first entity expansion will be the expansion of casting margin taken into account, and then a review of its machinability, and then layered, programming, under the expected, single-programmed. Through a fixed sequence of programming operations can be programmed to reduce the error rate, but also can accelerate the training of new people.
The quality of the procedure depends on two aspects, one is pre-programmed stratification, and the other programming skills. Good stratification can improve material utilization and reduce labor intensity, while the convenience of the paste after the sequence. Stratified based on the principle that:
(1) First of all, consider the scope of the processing machine, the machine tool factory processing capacity limitations, the greatest material can not exceed 2000mm 4000mm 500mm;
(2) for the block foam material, size 5000mm 1000mm 500 mm, so that when there is cutting the size of the best use of existing materials to meet the size, reduce the workers cutting and pasting the time;
(3) stratified margin to be part of the paste have a good cushion to prevent the layered processing plane and non-processing side of confusion, missing allowance, such as the bottom, insert, retaining wall, guide plate, surface-oriented, Taiwan, such as spring;
(4) to consider when stratified good hand-machined parts and machining parts, such as the location of some are not suitable hole can be used to reduce manual way;
(5) ear hanging part of the complex processing procedures, numerical control processing is completed, the quality not as good as hand-made look good, so should try to avoid numerical control machine tool processing, hand-made by the workers;
(6) stratified as much forming machine as possible not less than the thickness of 100mm, or processing difficulties.
Mode under the edge of a mold base to cite the following examples to illustrate the paste and the process of stratification and Notes:
Entities to get after the first contraction than expansion in the volume of UG in the paste processing, and then consider the stratification. This piece can be divided into two tiers, divided into yellow and blue, and red for the to get rid of the volume, processing is complete, manually paste these parts. Taking into account the stratification is on the slippery slope is expected, if the points directly on the slope it will lead to partial thin brown, not processing. Therefore, when layered, not to choose the level of segmentation directly, but the first partition and then down the level of segmentation, so that part of the weak have been strengthened.
