Preparing CAD models for manufacturing
Design functions for the NC programmer
CAD data must often b 385213253 e prepared before NC programming. For example, you need extension and rounding surfaces, area and center curves, closing faces over recesses etc. The geometric form of the blanks often also still has to be designed.
Tebis provides NC programmers with easily usable CAD functions with extensive analysis functions. With these functions, design changes are quickly detected and radii, planar surfaces and undercut areas are quickly found and marked. Functions for determining dimensions and inserting texts are included in the standard scope.
A prepared CAD model lays the groundwork for automated CNC programming: In many cases, NC programming can then proceed automatically in Tebis.
Analyzing geometry
Tebis offers extensive functions for analyzing geometry:
- Calculate lengths, surfaces and volumes for costing and ordering materials
- Determine dimensions like coordinates, length, radius, distance and angle
- Real-time intersection functions through the part
- Compare two versions to detect changes
- Detect and identify bores
- Detect planar surfaces, for example for defining tool lengths
- Detect and identify roundings
- Compare two manufacturing stages to determine the remaining material to be removed
- Detect geometric steep areas and undercuts to define appropriate milling directions
- Detect surfaces with quality features that have not been complied with, including gaps, high segmentation, and overlapping surfaces
- Analyze curvatures for evaluating surface quality
This video shows various analysis functions for this mold part:
- Determine dimensions
- Analyze roundings
- Detect undercuts
- Detect planar surfaces
- Detect bores
The video shows several analysis functions on this sheet metal die:
- Determine dimensions
- Analyze planar surfaces and roundings
- Determine slope relative to Z axis
- Detect bores
- Real-time intersection function
- Material thickness analysis
Inserting fill surfaces
Fill surfaces are often used before the calculation of NC programs, for example in the area of recesses and slots. The part will be simplified and decomposed for a better overview. Tebis also offers convenient functions for this purpose.
Inserting features
If parts contain NC features from the Tebis feature library, then subsequent 2.5D NC programming can be performed completely automatically. This is handled by the feature scanner: It converts the design feature into an NC feature that includes all relevant machining information.
Designing blanks
Tebis offers several automatic design functions for defining blanks:
- With a part envelope
- With a casting allowance
- As a layered blank
- As a 6-sided blank
Extending surfaces
Surfaces are extended by simply moving the drag arrow.
Creating guide curves
Special high-end milling functions such as machining deep slots require guide curves that the NC programmer creates using a wizard.
Detecting sharp edges
Preparation function for fast 5-axis deburring. Tebis automatically detects all sharp edges in a part. Areas such as countersunk bores that are deburred during the boring process can be excluded from machining .
