Key takeaways

Tebis belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Tebis to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Tebis from memory before moving on to harder problems.

Functionality Tebis is a CAD/CAM software for industries such as die, mold or model manufacturing. The software is primarily to create toolpaths for machining operations such as drilling, milling and turning, but also for Wire EDM and sinker EDM. These toolpaths control multi-axis CNC machines. Other applications include manufacturing planning, design, reverse engineering, quality assurance, CNC machining and assembly. The software features interfaces for neutral file formats as well as proprietary formats of third-party manufacturers (STEP 203/214, VDAFS, IGES, DXF, STL, Parasolid, Catia V4/V5, Creo, SolidWorks, NX, JT, Inventor, Nastran, AutoForm).

Industrial application The programs are used in manufacturing companies of all sizes, from small and medium-sized companies to OEMs in the automotive and aerospace industries and their suppliers. The following is a small sampling of companies who use the CAM system from Tebis.

The history of Tebis Tebis was founded in 1984. Following initial consulting jobs and business software projects, Tebis shifted its focus after six months to CAD/CAM. The first technical product was a PC-based station, which used a drawing board equipped with a position-measuring system to digitize transparent plans and convert them to scribed programs for milling machines. Version 1.0 was the first Tebis CAD/CAM system, exclusively for MS-DOS. Two monitors were required: One monitor displayed the real commands, while the other showed the geometries in 4 panels. The input commands were entered using a digitizer tablet. The milling programs were calculated only for individual surfaces. Because of the small RAM (256 bytes) in the NC machines of the 1980s, Tebis provided a DNC connection to enable postprocessing via a V24 line next to the NC machine. Tebis Version 2.0 with a graphical user interface was introduced in 1989. It is still used today in a much more advanced form, and is distinct from common Windows interfaces. This version made it possible to animate geometries onscreen in real-time. Tebis Automill technology, which allows users to calculate milling paths across surfaces, was introduced in Version 2.1. Tebis Version 3.0 was presented in 1993. The system was modularized and expanded for operation under the SCO UNIX, HP-UX, IRIX and AIX operating systems. Version 3.1 included the Milling Wizard, version V3.2 featured interactive CAD and version V3.3 offered the first integration of a tool library and parameterized administration for all NC calculations. In Version 3.4, modules for the simulation of machining at a virtual CNC machine the design of electrodes for EDM, and 2.5D milling and drilling were added. Starting with Version 3.5, variable machining templates can be used for even better NC programming automation. For the first time this version also included the Job Manager as a central control element for all machining steps. The CAD module for BREP design was integrated in the software, enabling Tebis to be used for the entire manufacturing process in die, mold and model manufacturing. Version 4.0 was provided with a new user interface specifically designed for CAD/CAM applications and a new platform for 2.5D and 3D feature-based NC automation. For the first time, this version supported CNC lathes and industrial robots, and the manufacturing technologies of laser hardening and laser weld cladding. The current Tebis Version 4.1 was launched in 2020 with an internally-developed parametric-associative CAD system base. The hybrid CAD system combines free-form surfaces, solids and digitized data and provides Tebis template technology also in the CAD environment. Parametric CAD templates automate design and CAD manufacturing preparation. The user interface has also been optimized in terms of simplicity and automation for CAM users. Tebis is one of the global market leaders in CAM software. The owner-managed company also has its own consulting unit working with companies primarily in die, mold and model manufacturing. Services include industry-specific process and management consulting and optimizing the processes of these companies. After acquiring a division of ID Ingenieurgesellschaft für Datentechnik mbH, Tebis now also offers a manufacturing execution system (MES) called ProLeiS that can be integrated in the CAD/CAM application.

Worked examples

Example 1 — a first encounter with Tebis

Start with the simplest possible case. Write down what Tebis claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tebis before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tebis ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tebis

In research: Tebis appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Tebis in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Tebis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer-aided design software, Computer-aided manufacturing software, Digital manufacturing, so understanding it makes those chapters shorter.
In everyday life: Look for Tebis outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
