Silma X4 1

Inspect with confidence

Improve your 3D measurement experience with a winning combination: Silma, for advanced simulation and digital twin of your 3D measurement process, and Metrolog for on-machine execution and analysis.

Next generation 3D Metrology.

Why simulation is so important for building your quality inspection?
Silma X4 2

Better throughput

First, when metrologists program offline inspection tasks on complete simulated twins of their actual environment and equipment, the CMM or the robot are free to continue measuring and monitoring.

Silma X4 3

Improved efficiency

Second, when inspection programs have been simulated and virtually tested, they are error- and collision-free once applied to the manufacturing process.

Silma X4 4

Faster programming & results interpretation

Third, an offline simulation program like Silma X4 or Silma X4 i-Robot can work directly with native or neutral CAD files and automatically interpret GD&T.

Training & Education accelerator

Our simulation software, Silma, can also be used for training purposes, as an e-learning tool.

Workcell and virtual
environment definition

DCC CMM; Laser Trackers; Probe library; Accessory library

Silma integrates an extensive CMM library including the real machine cinematic as well as detailed probe heads, probes and styluses and accessories. Parts to be measured and their associated fixtures can be directly loaded as CAD files and easily set in the 3D virtual machine environment.

Offline programming

DMIS or Native; Post processors; Part program import

Silma has been developed not only to create and simulate part programs but also to entirely validate and troubleshoot them using advanced probing and measurement routines and constructions. Based on a programmer oriented and intuitive interface, part program proofing is fast and easy.

    Part program validation

    Colision detection; Probing path optimisation; Advanced functions

    Silma includes a true 3D inspection and analysis engine capable to validate your program consistency. In addition, its collision detection and automatic collision removal tools give you the ability to visualize, optimize and update in real your entire program probing path.

    Part program execution

    Graphical reporting; Report editor; Customisation

    Silma is capable to create part programs directly in Native DMIS or in X4 proprietary format as well as to export them in many other native formats, including: Quindos™, Umess, … The programs can then be run directly on the CMM for final online validation and immediate utilization.

    From design to measurements

    Silma programmer interface was developed to easily and efficiently create simple to extremely complex part programs using high level language commands.

    Based on its fully customizable virtual world environment and the CAD files of the parts to be measured, the initial set-up and completion of a part program can be done without having any real CMM downtime: the program can be sent to the machine virtually error and collision free!

    Flexible and universal

    Silma includes a virtual library of more than 500 machines (DCC and Manual CMMs, Laser trackers, changers, rotary tables…) and all the other needed accessories needed to replicate your real world environment (Renishaw™ and other OEM probe library accessories, universal fixtures…).
