Preparing CAD models for manufacturing
Fast and easy to modify
Precise preparation of the CAD models is the basic prerequisite for almost completely automated NC programming. Manufacturing preparation can also be quickly performed, mostly with a high degree of automation. Tebis also offers highly convenient functions for interactive intervention: for example, to close complex recesses. Processes can be more easily planned with extensive options for part analysis.High data qualityResulting high manufacturing quality and short manufacturing timesHigh efficiencyStandardized and automated NC programming is possibleAlways readyFast learning curve for employees during NC programmingAutomated data preparation with CAD templates
Place holes for setup systems, design fill surfaces for roughing, prepare blanks, generate connection points for various setups, position clamping devices, define retract planes – these are all typical examples of repetitive tasks that can be combined in rule-based CAD templates. The CAD data prepared in this way are immediately used in automated CAM programming. All that your CAD/CAM users have to do is select the part and specify the machining direction – and the system takes care of the rest.
You still remain highly flexible: Changes like selecting a different clamping system can be controlled directly and conveniently with the user parameters in the object tree. Parameters like the length, radius or direction of elements can also be modified with the click of a mouse.Inserting features
The video shows how the Tebis feature scanner analyzes the part and automatically inserts appropriate features.Features contain manufacturing information and are linked to standardized NC sequences. The Tebis feature scanner detects prismatic areas that can be manufactured automatically and converts the design feature into an intelligent NC feature.Design functions for the NC programmer
Sometimes the NC programmer has to intervene interactively during data preparation: for example, to generate complex fill surfaces and extension surfaces or area and center curves. It may also be necessary to first design the geometry of the blank. These tasks can be quickly and easily performed with Tebis. Parts can also be simplified and split for a better overview.Create complex fill surfaces

Design blanks
Defining blanksTebis 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
- With an extruded profile
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 haven’t been complied with, including gaps, high segmentation, and overlapping surfaces
- Analyze curvatures to evaluate surface quality
