Tebis 4.1 is a complete CAD/CAM system that’s designed for intelligent manufacturing. It enables CAD/CAM users to perform tasks in design, manufacturing preparation and NC programming in a single system with a high degree of automation. Tebis presented the most important new developments in CAD and CAM at the EMO in Milan (4th – 9th of October). Tebis is consistently moving forward with greater automation, user-friendliness and practical implementation. It has clearly demonstrated the many advantages of rule-based procedures by drawing on its proven internal expertise with both CAD and CAM applications.
Faster preparation for manufacturing: Highly automated, flexible preparation of CAM programming with parametric CAD templates
Every imported data set has to go through a design process to be prepared for CAM programming. This usually takes 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 many individual steps can be automated in Tebis using parametric CAD templates. These templates can be extended as needed and modified to meet customer-specific requirements. Users can remain flexible: changes like the selection of a different clamping system can now be controlled directly and conveniently with the user parameters in the object tree.
Optimal cutting conditions for roughing rotationally symmetrical parts
A real plus for combined turning/milling operations: In addition to cylindrical parts, now tapered parts like screw conveyors can also be machined with high efficiency. The tool first roughs the part to the maximum possible depth with a low stepover and large downfeed 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.
Improved support for multi-channel machine tools
This innovation is beneficial for manufacturing companies that rely on combined turning/milling operations, especially if the components to be machined have a high milling fraction: Tebis can now be used to program toolpaths for sequential processing on machines with multiple tool and component holders. The individual steps – like milling with a milling head or turret, stabilizing with a centering tip or clamping with a sub spindle – can be combined in any way. All tool and component holders are stored in the virtual Tebis process libraries, which can be interchanged quickly and flexibly during programming. As always in Tebis, all system components are fully accounted for in collision checking and simulation. Programming is incredibly easy. Tebis automatically generates NC code for any machine and supports all control-specific program structures.
Easily machine surfaces with 5-axis barrel cutters
Tebis also introduced a function that simplifies programming of multi-axis toolpaths for pre-finishing and finishing with circle-segment cutters, also known as “barrel cutters.” It automatically determines the best setting for manufacturing the machining area totally free of collisions. The function simultaneously calculates the optimal contact point at the surface boundary to ensure material removal over the largest possible area. Machining is indexed or 5-axis simultaneous: the user can independently specify the preferred variant or can leave the decision up to the system.
