Taking optimised manufacturing to the next level

By Bhalchandra Chorghade, Editor, CNCTimes.com

The third release of Tebis 4.1 now comes with even more new developments which include: shorter programming times with improved NCJob technology, complete collision control accounting for material removal and automatic detection of 2D areas.

These are just a few of the latest developments that benefit the software’s users in their daily work and allow them to quickly and easily reach their work goals.

As a robust hybrid CAD system with logical and intuitive user guidance, Tebis 4.1 lays the foundation for manufacturing processes that can be automated and prepares users for a digital manufacturing future. 

CAM Automation

Programming time is now shorter thanks to improved automated NCJob technology. The new release automatically applies interactively defined milling areas from previous NCJobs. CAM programming is also significantly simplified as users can easily manage combined machining operations in an end-to-end CAM template, meaning CAM programs are finished more quickly.

CAM Milling

When it comes to milling, there are optimised cutting conditions for roughing rotationally symmetrical parts. With turn-mill operations, in addition to cylindrical parts, tapered parts such as screw conveyors can now also be machined with high efficiency. The tool first roughs the part to the maximum possible depth with a low stepover and large down feed in a single pass. Then, it machines the residual stock from bottom to top with a smaller cutting depth – precisely to the stock allowance.

This procedure reduces tool wear and ensures a high material removal rate on the machine. The user can easily program the final finishing operation with a special function. Only the strategy is replaced – the system does the rest.

CAM Lathe

With CAM lathe processes, parts can be cut-off from bar stock with a special function for automated machining on lathes or turn-mill centres. It can quickly and easily define the optimal cutting conditions for feed rate and speed on material exit.

CAD Active surface design

When it comes to CAD surface design there is now precise results when trimming, deep-drawing and bending parts. The Create Development Curves function can be used to quickly and easily determine theoretically designed trim edges for flanges on deep-drawn and bent parts. The material thickness of the component and the location of the neutral fibre are accounted for – and the result is highly precise, with no manual reworking necessary. The quality of the resulting curves corresponds to that of the original curves.

CAD Parametric design

Another feature of Tebis 4.1 is parametric design. Every imported data set needs to be prepared for CAM programming in design which usually involves many individual work steps: bores for clamping systems must be placed, tilt axis systems defined, fill surfaces designed, blanks created, connection points for setups generated, clamping devices positioned and retract planes defined.

These numerous individual steps can be highly automated in Tebis using parametric CAD templates which can be extended as needed and can be adapted to meet customer-specific requirements.

Users can still be highly flexible as changes like selecting a different clamping system can now be controlled directly and conveniently with the user parameters in the object tree.

Lastly, when it comes to drilling, the new release simplifies the use of special cutters. When using combined special cutters with several cutting edge areas of different diameters, only the diameter of the active cutting edge determines whether the tool is suitable for the specific machining task.

This enables highly flexible use of special cutters for drill-milling and thread-milling in bores and circular pockets – regardless of the diameter of the largest cutting area. The plausibility check also only accounts for the properties of the cutting area actually used.
