Mold Design Applied Skills
UG in the mold design, has a large number of application skills, proficiency in these skills, and analogy, will give you in the work to bring very great convenience, Mold Design especially in the complex products in the process of separation, can be less detours to reduce blindness.
In UG operation, it is often encountered that Boolean operation is not added, reduced, and cut, division failure and so on. Especially in the face of a bad situation, the model, Mold Design take the slider, inclined top often encountered such problems, can try to use the following methods:
1. The specific surface of the work to offset or move a little distance to solve. (offset or moving distance without affecting machining accuracy)
2. Use wireframe to display target body, Mold Design work concretely, then do Boolean operation (or cut, divide) if fail, observe carefully, some of the edges will be found red, which is the problem area, the problem area can be separated (that is, divided into two parts), Mold Design then Boolean operation, and then the problem area surface, stitching, processing, and then patch up, this method can solve most of the Boolean operation failure. (The problem surface can also be offset slightly to solve)
3. Sometimes, the Boolean operation fails, Mold Design can all be made into a face, operation surface, and then stitched into an entity. This method can deal with almost all the problems of the failure, but it is also the most troublesome, it is not recommended.
4. Use physical suture to add two objects, Mold Design first select common surface, adjust tolerance to sew. But this approach can cause trouble for subsequent operations.
Boolean operations that produce multiple individuals will lose parameters, which is one reason why Split failures in Mw Moldtools are executed.
In the entity area, the chip body can not have "boundary" or "face self turn" problem, which can be checked out by the Face and Sheet option in Analysinegaminegaminei.
Boolean operations cannot have a "0 thickness" phenomenon.
In Boolean operations, you can "face-face, face-entity." These two options are very convenient to fill in the split.
1 Surface reduction: extraction of holes around the hole, remove the parameters, then use Boolean operation, surface reduction of the way, will break the surrounding surface of the hole to remove, and then the extracted surface sewn up (if necessary, the suture tolerance can be slightly adjusted), Mold Design but also to expand the extraction surface, or trim, and then suture. If the Boolean operation fails, the surface around the hole can be extracted, and then Boolean operation. After copy has been extracted from the surface, Mold Design handle the broken face, and then suture.
2 Cut the slice body to extract the surface or the periphery to make the backup. Cut out the broken surface or surrounding surface of the original geometry with the Trimmedsheet (trimmed piece) option. Then use the backup of the surface, after editing, and then restore up to one by one stitch. If the break surface is a small hole, can be used in the "freeform feature" in the option, manually do I piece body, fill up. Mold Design If there is still a hole in the suture, the suture tolerance can be slightly adjusted, after being made into an entity, with the function of "replace" or "constraint surface" to be repaired. (Physical trimming is sometimes much easier than a piece of body)
3 Change the broken face to another color, the rest of the surface color is consistent. Then use the Mw Molegion option to extract the same color surface, open 29 layers, you can see that there is no want to delete the surface, so it is easy to repair.
4 Sometimes, from other software to the IGs diagram, the surface has been seriously deformed, can be used contour lines, hand action surface. If the contour line is broken, Mold Design these places can be cut off and processed.
5 If a lot of broken face, can all be extracted into one of the scattered, and then one by one suture, you can find the problem.
6 There are many STP maps from other 3D software to analyze it as an entity, but careful observation, but there are holes, this is a geometric problem. At this point can be extracted one single piece of body, and then stitched to solve. Also can according to Contour line, oneself hand face, again do patch.
7 UG Open Other software output IGs map file, the effect is not very good, in many cases there is a piece of deformation, you can first use SolidWorks software to open, and then save as Xinte format, input UG, at this time, we can find that the quality of the graphics greatly improved.
8 Sometimes, it can be much easier to increase the stitching tolerance, artificially sew the piece into an entity, and then modify it in the entity. Remember, if the piece is not easy to modify, can be made into an entity first, if the entity is not easy to modify, can be made into slices.
9 The main tools of solid patching are: Patch body (patch), simplification, replacement, constraint surface (Constrain Face), delete surface.
