KOMPAS-3D provides allows users to prepare a model (part or assembly) for the development of the technological process of its manufacture (or assembly). For this purpose a technological assembly is used.
Technological assembly is a three-dimensional model containing process data, for example, the result of recalculating the dimensions of a model with allowances, technological objects (center holes, mounting holes, etc.), technological models (rest devices, centers, tools and other equipment). The technological assembly is created and stored in the "technological assembly" document ( t3d file extension).
Use examples of the technological assembly:
Example 1
The designer has created a part. To develop the process of manufacturing this part, the process engineer creates the technological assembly, includes the part in it and adds the required process data.
Example 2
The designer has created a general assembly of a gearbox. Two gear housings need to be processed together. Models of these housings are in different subassemblies of the general assembly of the gearbox. The process engineer creates a technological assembly and includes two gear housings in this assembly. Then the process engineer adds the required process data to this assembly for combined processing of the housings.
The technological assembly may consist of any objects included in the usual assembly of KOMPAS-3D (see section Model in KOMPAS-3D).
Operations with a technological assembly – adding components, creating and editing solids and surfaces, creating matings, etc. are similar to operations with a standard assembly.
The following procedure for creating a technological assembly is recommended.
1.Create a new "process assembly" document.
2.Add the required components (parts and/or assemblies created by the designer).
3.If required:
•edit the model by performing operations in the technological assembly;
•recalculate the model dimensions based on tolerances;
•add:
•technological models and stock products as components;
•process data.
|
If during the work with the technological assembly a change in the composition of the assembly is expected, then we recommend to fix its components. To that end, you can highlight the section Components in the Design Tree and call the Enable Fixation command from the context menu or from the Assembly menu. |
|
Component changes made using the operations in the technological assembly are not exported to this component file. These changes are stored in the technological assembly. At the same time, model changes made when editing the model file are exported to the technological assembly. |
|
If a technological assembly is created from a standard assembly using the Save as...command, all subsequent changes to the original assembly will not be exported to the technological assembly. |
By default, components are added to the technological assembly with nominal dimensions. In the assembly you can change the dimensions of each component, taking into account the tolerances assigned by the designer for the component dimensions (dimensions of the sketches and dimensions corresponding to the parameters of operations; see section Dimensions of sketches and operations). For more details on managing component dimensions in an assembly, see section Tolerances in component size management.
