The Digital Twin

Full integration with all common CAM systems

Complete, accurate collision control

Exact simulation of all movements

Reduce machine downtime to a minimum


Avoid machine damage, downtimes, failures and make your production and programming even more efficient & error-free with NC2Check.

The g code simulation NC2CHECK from CAMWERK offers you a complete mapping of the entire machine tool and simulates nc programs based on the real g code after the postprocessor run.

Complete machine simulation with all machine details. Detects collisions, travel limits, damage to the workpiece and the CNC machine before the actual machining.

Supports all common controls such as Siemens, Heidenhain, Mazak, Fanuc, Hurco and many more.

Less machine downtime

Reduced set-up time

No corrections on the machine

Shorter run-in times

Collision control

Feasibility study

Virtual retraction

Digital twin

Collisions, component violations or exceeded axis limits occurring in the nc code based machine simulation are listed in the report so that they can be precisely verified and checked.

This also makes the correct positioning of the corresponding component or the clamping device much easier and, of course, safer.

NC2Check supports all common machine controls such as Heidenhain, Siemens, Fanuc, Haas, Hurco and many more.

Significantly reduce run-in times!

Simulate a wide range of machines & controls with a 1-click solution on nc basis!

Boost productivity & efficiency significantly!

Simulate & verify complex machines very easily!

Absolute collision check!

Exactly 1:1 emulated controls!

Very fast simulation run

Real time material removal

Very easy to use

All necessary functions included in the standard

Real time collision control

Why NC2Check?

Advantages of NC2Check are very easy explained:


NC2Check runs on the ModuleWorks surface and can therefore be integrated into CAM systems very easily and smooth. Our parser interprets a code and the underlying logic and, in our case, feeds it to a virtual controller/machine to create a virtual process in NC2Check.





The famous Digital Twin! Machine simulation based on the real nc code!

Compatible with any CAM system and very easy to integrate!

Goals of using NC2Check?

1-Click Solution

NC2Check is started directly from your CAM system.


With “one mouse click” all necessary data is transferred to the nc code based machine simulation NC2Check.

Tools and holder


Finished part

Stock part


Machine offset

Nc program

NC2Check precisely simulates your cnc machines and the whole process of machining.


By verifying your nc code through NC2Check, you have an nc code based virtual machine simulation.


Detect errors that lead to machine downtime, damage to the workpiece or even expensive collisions on the CNC machines BEFORE! the real machining.

Smooth integration to every CAD/CAM system

Same user interface with CAD/CAM systems

Very easy to use

No training needed

No additional software needed
