Tebis presents new Release 4 of its current Version 4.0 at the Moulding Expo
Tebis CAD/CAM software: New Version 4.0 Release 4
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 Moulding Expo 2017. This latest release includes many new and improved CAD/CAM functions that simplify work for die, model and mold manufacturers.
Nothing is as predictable as change. Tebis creates area curves during part comparison to enable better detection and limitation of modified areas. Design measures can be quickly implemented or new NC programs quickly calculated for modified areas.
A new function creates non-overlapping shifted surfaces at defined angles from any curves. All overlaps within parts that would result in 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 trimline 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 benefits 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 support 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 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 and acceleration ramps. This 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 the functions are now easier to operate. 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 — based on the respective part situation. For these tools, which are particularly 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 technology
Tebis Version 4.0 Release 4 offers new possibilities for machining with robots. Additional axes in robot cells can now be controlled as simultaneous NC axes, for example if the robot is mounted on a positioning unit. In these situations, the robot can be permanently positioned with the linear axes oriented to ensure that the arm is used within the optimal working area. With the new part-driven robotic machining, the robot can 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, enabling it to be used in a larger range of applications. Use of these technologies in die and mold manufacturing is on the rise. Combining them with milling and other shaping methods in a single comprehensive programming environment is a major advantage for customers.
