More CAD, more CAM, more automation, optimized measurement processes: Tebis 4.1 gives you many functions to make your entire manufacturing process even more economical and reliable.
CAD – parametric design
Quickly and easily create holes and pockets
The "Solid/Hole" and "Solid/Pocket" functions can be used to create parametric holes, threads and pocketsvery conveniently at different tilt directions: Simply select the ruled geometry with its complete description – such as for multi-step holes – directly from the feature library and insert it in the part. This increases process reliability and promotes consistency of the process work flows. As an alternative, you can design bores, threads and pockets interactively.
The bores and pockets can be subtracted from the component with just a few mouse clicks and can later be adjusted at any time.
CAD - Electrode design
Quickly and reliably design electrodes
Electrode projects can be created and managed as objects right in the new CAD structure tree. The key advantage: You store the part and reference point only once in the project – all the electrodes in this project then reference the same part and the same reference point. Of course, you can interactively modify conditions for individual electrodes at any time.
In addition, multiple geometrically identical electrodes can be automatically created and combined in an electrode family. For example, if you need geometrically identical electrodes with different spark gaps for roughing and finishing, this can now be very easily realized with a click of your mouse.
In addition, practical filtering ensures that the appropriate blank and holder for the electrode are selected. The blank is automatically oriented to the burn surfaces.
Manufacturing and measuring programs can also be managed through the structure tree. Electrode information is documented and transferred.

More control: Create CAD surfaces more precisely
When generating high-quality design surfaces, Tebis approximates, i.e. adapts, individual polynomial surfaces to the 3D scan and the designed curves, for example defined character lines. After this approximation, Zebra shading and curvature analyses often show that the surface quality in the transition areas between two main surfaces is insufficient.
Tebis 4.1 solves this problem. The new G0 loop radius can be used to assign an edge the special properties that the boundary curve takes precedence in approximating the surface. To do this, simply place a loop (red) around the continuous edges of the affected facet and specify the size – either predefined as the same size everywhere or manually adjustable with individual drag arrows. Tebis then immediately displays the change in the CAD surface for optimal surface quality.
Within the G0 loop radius (red), Tebis approximates the surface more to the boundary curve rather than to the scan data.
CAM – Automation
Quickly and easily change machining sequence
Subsequently change machining sequence
Convenient and reliable: If you intersect features with the "Cut" function, the selection sequence determines the machining sequence. The new "Sequence" function now enables this sequence to be subsequently changed. The gap areas adjust themselves automatically.
This is how the machining sequence can also be modified for existing feature groups.
Flexible NC programs with bore patterns
You can output NC programs with bore patterns to enable responses to changes that are not communicated through 3D data in drilling. Element selection in feature machining has also been extended, allowing you to select features in the same tilt direction and plane and with the same dimensions and NCSet. The resulting toolpath is then output as a bore pattern, which allows you to flexibly modify the drilling positions in the control.
Automatically detect spot face depth
Simplify machining of bores and standard pockets. Specific spot face depths can also be automatically determined when scanning features if they do not start on a planar surface. This value is entered in the feature as the pilot depth. Even if the pilot depth cannot be automatically determined, the "Automation/RuledEdit/Pilot" function can be used to specify a pilot depth for individual features based on a surface element. Reliable automatic processing of the standard pockets and bores with NCSet templates creates a spot face at the pilot depth.
CAM – Drilling
Quickly and conveniently drill multiple sections
Optimal for series production: Now use the "Drilling in sections" function to automatically create multi-step bores; different depths of cut and cutting data can be specified for each. You can do this by preparing the bores for machining with the revised "Link bore features" function.
The "Drilling in sections" function replaces the previous "Create toolpath for deep bores" function (MDEEP).
This function is also suitable for manufacturing welded frames for which fits often have to be created in multiple plates that have large free spaces between them. It can also be reasonably implemented in unit construction: for example, if sections with material and gap areas alternate in bearing guides.
Drilling in sections and link bore features
CAM – Milling
Prevent minimal residual stock areas in roughing
Prevent areas of residual stock
Depending on the manufacturing situation, you can now limit or completely preventresidual stock areas on roughing with the "Off," "Low," "Middle" and "High" area filters. If the "Off" option is selected, all residual stock areas are machined for a continuous stock allowance. Machining time is correspondingly longer. If the "High" option is selected, smaller residual stock areas aren’t machined. These can then be cleared with a smaller tool when re-roughing, for example. The "Low" and "Middle" options provide intermediate steps.
Reliable milling by accounting for the machine head
The video shows how easy it is.
Quickly create collision-checked toolpaths: In the event of possible collisions with the machine head, milling areas are automatically reduced or are excluded from the machining operation in the NC calculation.
You benefit from greater process safety and enjoy tremendoustime savings: Without automatic area reduction, you have to manually correct the collision after calculation and then recalculate the machining operation. With area reduction, you can use the shortest tools for every milling job, ensuring optimum cutting conditions.
Machine planar surfaces more efficiently
Cut division is now calculated from the flanks in axis parallel planar surface machining with the "2.5D milling/Roughing planar surfaces" and "2.5D milling/Bottom finishing planar surfaces" functions. Path sorting can now start from the outside or the inside. You can also machine correspondingly narrow areas with a single path with a freely definable center offset.
Finish contours with radius correction with downward machining
A new strategy is available for downward machining on contour finishing. This can also be combined with roughing in an NCJob and also generated with radius correction, if desired. This yields an optimized finishing process.
Contour machining with automatic avoidance
Protected surfaces can be avoided in Z-variable machining of contours. The tool retracts before the protected surface at a freely definable angle, traverses the protected geometry at the defined allowance and moves downward again after the protected surfaces. The entire length of the cutter is thus used even in difficult geometry and clamping situations.
Faster completion with separate offset values
An additional axial or radial allowance can be assigned to enable roughing with a different allowance in flat and steep areas. This additional allowance is added to the general allowance. For example, flat areas can be finished immediately afterwards, while steep areas are prefinished. Areas with negative overlap can be defined so that the tool does not engage too much material on steep flanks.
Quickly and reliably remachine fillets
Enable automatic determination of the maximum depth at which material is removed from fillets. This value is separately calculated for each fillet so that all fillets are completely machined. This enables fast and reliable work even with the smallest tools in your project.
Best milling results with circle segment milling cutters
Very high accuracy: Barrel, cone and drop cutter geometries can now be precisely represented by entering parameters: For the best surfaces, define the "ideal" contact point specified by the tool manufacturer. You can also define a range that is limited by a minimum and maximum angle. These specifications are used in calculating 5-axis simultaneous toolpaths for roughing and finishing contours and for side milling. If you select a constant slope angle, only the tangency point is taken into account for the tool tilt direction. When a variable slope is selected, the cutter uses the entire angle range.
Best surface quality with 3to5-axis machining
Machine the best surfaces with the "3to5-axis" collision avoidance strategy. The positions of the rotational axes are now better synchronized for adjacent toolpaths. The tool also pivots more smoothly to the new tilt direction in corners. The new analysis function in interactive calculation can be used to evaluate the tilt angle of the A/B axis, the rotation angle of the C axis, the change in angle per path and the height profile before manufacturing surfaces at top quality.
Targeted control of tool movements in 3to5ax machining operations
3+2-axis programmed toolpaths can be automatically converted to 5-axis simultaneous toolpaths. It is also possible to specifically influence the tool movements and thus optimally adapt the cutting conditions to the specific machining situation.
The "Interpolate vectors" option is useful for avoiding potential collisions with the machine head, for example, detected during the NC calculation: Select any number of designed linear curves as vectors. These determine the tool direction and traverse movements. The system automatically interpolates between adjacent vectors.
In the "Plumb element" option, selected guide elements such as axis systems, points, curves, surfaces, topologies or meshes are used to specify the tool tilt direction and traverse movements. These plumb elements always intersect with the tool axis. This option is especially recommended if better results can be achieved with 5-axis simultaneous machining than with 3+2-axis movements due to the surface shape.
In both options, you can select between fixed and variable tilting angles around the tilt axis. They can also be combined with automatic avoidance movements at any time.
Best quality with plumb elements
CAM – Lathe
Improved cutting data management for turning tools
Also make optimal use of your turning tools. A material-independent depth of cut (ap) can now also be defined for turning tools. These values can be automatically applied in contour turning and downward machining. This enables use of the best possible cutting data at all times on each machine group for each material and each machining type.
Reliable turning calculations with the tool carrier
Preventcollisions with the tool holder in turning during calculation. Regardless of whether your machine has a turret or a machine head, the machined areas can be limited if necessary to prevent collisions. This enables fast and reliable calculation of NC programs even for complex machining operations.
CAM – Machine technology
Convenient part transfer between main and sub spindles
Part transfers in machining centers with a main and sub spindle can now be simply, conveniently and completely controlled in the Tebis Job Manager. The part can be transferred with fixed or rotating spindles – with appropriate angle synchronization. Because the Tebis Job Manager contains all information on part length, clamping depth, chuck lengths and part movement via the unit library and setup, there is no need to worry about these – the necessary data are automatically transferred. If necessary, a cutoff and feed of the stock material can be included in the part transfer. This automatic part transfer – which is represented realistically in the simulation – enables reliable and convenient manufacturing on both spindles in your machining centers. This enables you to effectively use your equipment, increase machine utilization and increase flexibility.
Flexibly control machining centers
Machine-specific user parameters can be set in the configuration elements of virtual machines. This permits the behavior of the machining center to be controlled by machine macros. Numerical values can be entered, or selectable values can be provided. For example, the conditions under which tools are measured, how they are to be positioned and pivoted between tool paths etc. can be specified. Many machining details can thus be flexibly specified from the Job Manager.
More machining options with free-rotation axes
In the event of collisions and limit switch problems that can be prevented with a different head rotation, the kinematics configurations of your virtual machines can be used to set the rotation axis with a degree of freedom to the desired value. The selected machine positioning is retained when NCJobs are recalculated.
CAQ – Measure
Increased productivity thanks to measurement integrated in the process
Completely integrate your measuring tasks in the manufacturing process – easily and with reliable collision protection. For example, you can check to ensure that the part is correctly set up, the blank is correctly dimensioned and oriented and, after machining, that the part does not require any refinishing that would not otherwise be detected until after unclamping. All the necessary functions are now available in the MPoint menu – from probe calibration to point measurement, angle measurement based on points or circles, and circle and rectangle measurement to checking grooves and ribs. Integrated tolerance testing can be performed to determine whether the order can continue to be machined or must be interrupted. This results in a reliable and highly automated process with combined milling, turning and measurement operations that prevent damage to tools and machines. This results in shorter setup and machining times, higher component quality and fewer correction grinding operations. You can benefit from these functions even on controls that don’t have their own measurement cycles.
Clearly display and document measurement results
Measurement results can be directly represented relative to the part in the 3D CAD/CAM data. The file generated on the CNC control can be imported with the measurement results. This then yields the measured value, the deviation, the shape parameter and the tolerance band for the measurement. If desired, you can document the evaluation graphically and in table form as a PDF.
CAM – Job planning
Transform toolpaths with process safety
Symmetrically transformed toolpath
When transforming NCJobs, including mirroring, moving, rotating and scaling, you can now specify whether the NCJob needs to be recalculated on transformation, not initially calculated or whether only the toolpath will be transformed without recalculating the NCJob. If you want to quickly create a symmetrically transformed toolpath the ,"Transform without recalculation" option yields a quick result. This drastically reduces programming time. The NC code including machine cycles is automatically adapted to the travel direction of the toolpath. If the "Recalculate" option is selected, the NCJob is recalculated with the transformed or selected input elements. If the "Do not calculate" option is selected, you can prepare the NCJob and run the calculation at a later time, if necessary.
CAM – Laser cutting and trimming
Simple incremental movement of paths
Simplify the correction of modified machining operations in laser cutting and trimming. The path correction values can be input in increments. This reliably yields a new machining status without input errors.
