Design
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 mould 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 colour 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.
Manufacturing
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.
Tebis Version 4.0 Release 4 simplifies automated deep-hole drilling based on bore information stored in the part
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.
Quickly and effectively machine pockets in 5 axes with barrel cutters—the tool contact point is automatically adjusted to the specific part situation
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 optimise 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.
