Tebis CAD/CAM software: New Version 4.0 Release 4
Tebis presents new Release 4 of its current Version 4.0 at the Moulding Expo
Tebis, the process provider for the development, design and manufacturing of models, molds and components, presents the new Release 4 of its current Tebis Version 4.0 for the first time at the Moulding Expo 2017. This latest release includes many new and improved CAD and CAM functions that simplify work for die, model and mold manufacturers.
Nothing is as consistent as change. Tebis creates area curves during part comparison to enable better detection and limitation of modified areas. Design measures can thus be quickly implemented or new NC programs can be quickly calculated for modified areas.
A new function creates non-overlapping shifted surfaces from any curves at defined angles. All overlaps within parts that would result especially at sharp edges and small radii of curvature are automatically filtered out and smoothed. These surfaces are ideal for separating part surfaces in mold manufacturing as well as for trim steel and trim line surfaces in draw die manufacturing. As is usual for Tebis, the lengths and angles of surfaces can be conveniently and interactively adjusted using drag arrows.
In addition, parts can now be automatically morphed together with the most complex trimming curves in surface morphing. The geometry of the original curves is fully retained and color properties are transferred 1:1.
Curves can now also be included in surface morphing. This results in benefits in draw die manufacturing, for example: If the active surfaces have to be morphed to compensate for springback of the sheet, all trimming curves can be morphed as well to yield the geometries for a correctly trimmed sheet metal part in a single step.
For example, deep-hole drilling in the CAM area has been better oriented to supporting automated calculation and machining. There is also a new tool type with an extended set of cutting data and special speeds, feed rates, cooling types and depth sections needed for deep-hole drilling. These values can thus be separately managed for each individual tool.
There is a new machining function suitable for this tool type that perfectly manages the special requirements of deep-hole drilling such as threading, intersections of bores or acceleration ramps. This even further simplifies automated deep-hole drilling based on drilling information stored in the part.
The definition of toolpaths has been further simplified in 5-axis milling and operating convenience of the functions has been improved. Options have been included for fast vector smoothing and for tilt-optimized calculation of toolpaths even without manual definition of vectors.
When using barrel cutters, the tool contact point can now be better controlled – according to the respective part situation. For these tools, which are especially suitable for machining cavities, it is often better to first start with a slightly greater slope with a tool contact point that is closer to the cutter tip. The slope can then be reduced to optimize tool wear. The slope can be increased at the bottom of the pocket until the cutter tip (ball) exactly contacts the fillet between the flank and bottom. This removes the residual stock at the end of the flank.
Robots and new technologies
Tebis Version 4.0 Release 4 also offers new possibilities for machining with robots. Additional axes in robot cells can now also be controlled as simultaneous NC axes, for example if the robot is mounted on a positioning unit. It is especially practical here to permanently position the robot with the linear axes so that the arm is used within the optimal working area. With the new part-driven robotic machining, the robot can now guide a workpiece past a tool that is in a fixed position in the robot cell.
Tebis now supports laser hardening and laser weld cladding, thus, can be used in an even larger range of applications. As both technologies are being used increasingly in die and mold manufacturing, it is highly advantageous to be able to combine these with milling and other shaping methods in a single comprehensive programming environment.
