CNC Simulator – pure reality

The Tebis CNC Simulator brings the workshop to the desktop

With Tebis, all of your machines – with all their geometric and kinematic properties – can be simulated 1:1 in the virtual world. The virtual machine lets you generate collision-checked programs that are absolutely reliable and true to reality. You can simulate the machining operation directly on your desktop and check for collisions with all components. This enables you to ensure that only completely collision-checked NC programs are sent to the machine. The entire machining operation runs flawlessly, right from the start: Multiple machine operation and unattended manufacturing are easily possible with the CNC Simulator. Of course the CNC Simulator also provides you with an outstanding planning tool with which you can check feasibility in advance and prevent collisions. 

Calculate and plan using the CNC Simulator

The CNC Simulator puts you in complete control right from the start. You have all the key data to prepare a detailed cost estimate and manufacturing planning: You select the suitable machines, machine heads, clamping devices, shuttle tables, units and tools from your available resources. You define any reference points, the values of which can be imported for the setups in NC programming. And you know how many machining operations are required overall. 

Select appropriate machines

The Tebis CNC Simulator supports the entire spectrum of commercially available machine controls and all established machine types. The machine library comprises more than 1,400 virtual machine models from different manufacturers in 3,700 variants. If desired, we can measure your machines – including all auxiliary equipment – on site. 


The Tebis CNC Simulator also realistically simulates complex multi-axis machines, multi-function machines such as turning/milling machines and lathes with main and secondary spindles

Detect and avoid collisions

Even before NC programming, you can use a special planning function directly on the virtual machine to traverse the tool along critical part areas – such as cavities, deep bores and undercuts – and view a display of potential collisions. If necessary, you can exchange the machine head and select tools with the appropriate programming length. The CNC simulator is so precise that, right from the start, you can carry out planning using the shortest tools possible. This enables you to benefit from high feed rates in manufacturing. You can quickly and easily create necessary tilt axis systems with the simple click of a mouse. You can avoid having to wait until collision checking to determine that tools need to be exchanged and NC programs recalculated. You can immediately start programming with the right setups, tools and tilt directions.

By using the tool library during the planning phase, you can program using the right tools from the very outset

The analysis functions display distances and angles between part and machine components. Programming lengths and tilt angles can thus be easily defined

Collisions between the part and machine head can be detected at an early stage and prevented by switching the heads

Programming with the virtual machine

During NC programming, you can set up the machine in the Job Manager with clamping devices and units such as jaw chucks, steady rests and the tailstock. The machine run times are determined with high precision. You can also access all macros that have been preconfigured for the loaded machine.

Robots with additional axes


The configuration elements enable you to remain highly flexible : Even in the middle of a machining operation, you can place units and clamping devices at any position or change the starting values for additional axes such as gantry axes, quills or rotary axes. 

In this example, the V axis is positioned via configuration elements. Additional axes can be positioned by user definition or automatically

Collision checking for maximum process reliability

You perform the simulation and collision checking during NC programming before postprocessing. You can optimize the machining operations and adjust them to the actual manufacturing situation. The key advantage: You do all this directly on your desktop, with no need for synchronization with the postprocessor or networking with the machine. This is significantly more convenient, reliable and efficient than having to reimport the corrected NC code into the CAD/CAM system. Time-consuming and cost-intensive approach processes are eliminated. The machine operator has no need to worry about potential collisions and can focus on his or her actual tasks. All components are completely checked, even in the case of multiple setups. Collision checking can also be performed in the background: You simply continue working in parallel. 

Realistic simulation

Machines, heads, clamping devices, units, mounted parts, parts, blanks, tools, tool changes, working planes, setups, starting points and connection conditions, axis limitations such as limit switches, axis and traverse movements with all stepovers and intermediate movements, machining plausibility – the CNC Simulator checks the entire machining scenario. You can select whether you want to check and simulate individual machining operations or all of them at once.

Application-oriented optimization

In complete collision checking, all conflicts such as cutter collisions, head collisions or limit switch violations are clearly presented and structured in a list. You decide whether you want to accept or correct detected conflicts based on the application. Your modifications are saved in the toolpath and are included in the postprocessing output. 

You have various options for optimizing your NC programs depending on the machining situation:

Replacing or editing tools in the tool library

Changing the setup position

Adjusting freely rotatable axes

Exchanging the machine head

Switching the head orientation

Selecting different machines from the machine library

Flexibility in the workshop

The CNC simulator is also indispensable in the workshop. The machine operator obtains information on blank and part geometries, setups and the tools used. And if the machining operation still has to be adjusted on short notice – such as in the case of a machine outage or if tools are eliminated – this can be done easily. Technology data such as feed rates or spindle speed, setups or the processing sequence can be quickly and easily changed. The affected toolpaths can be rechecked for collision with the click of a mouse and output via the integral postprocessors.

What our customers are saying:

A critical aspect for us is that we can thoroughly check our programs under realistic conditions before we implement them in the workshop. Using Tebis enables us to perform unattended manufacturing with peace of mind.

Ryan Hotchkis, Head of Manufacturing, Integrity Tool and Mold


The Tebis simulation solutions check all machine components and limit switches. This enables us to optimize manufacturing processes, reduce programming time and increase throughput right from the outset.

Martin Chaput, Resource Utilization Manager, Omega Tool Corporation


Safety for the tool, the machine and of course the operator are extremely important to us – and this is yet another area where Tebis simulation technology, with its collision avoidance options, really stands out.
