G-Code Simulation


Detect & Eliminate Collisions, Surface Gouges & More with a High-Precision CNC Simulator


Compared to traditional APT-based simulation systems, which only simulate the planned tool-path, ICAM’s Control Emulator™ delivers for a more meaningful simulation, accurately recreating how the machine tool will react to the G-code generated by your post-processor.

The simulator provides a powerful validation method allowing users to determine the association between G-code and specific operations inside the NC program and allows for specific modifications to the CAD/CAM NC program depending on the simulation results.


Compatible with Multiple CAD/CAM Systems


ICAM’s Control Emulator™ is built with maximum compatibility in mind. It supports all major CAD/CAM systems including Mastercam, CATIA, & Siemens NX.

Supports All Major CNC Machines & Controllers


No matter the make or model of your CNC machine-controller pairing, ICAM’s Control Emulator can be customized to make the most of its potential. Designing around precise dimensions and kinematics specs is the secret to providing you with production-ready G-Code that has been completely optimized for your given CNC machining process.

Seamless CAM-POST Integration

ICAM CE is fully integrated with CAM-POST, ICAM’s leading edge NC post-processor development software; therefore, users may employ advanced features inherent to CAM-POST. As a quick start, CE may be created from existing post-processors generated by CAM-POST and subsequently, all post-processor data modifications will be reflected automatically in the CE.

Shortened Learning Time for CAM-POST Users

CE utilizes the same macro language as CAM-POST for advanced customization features. All defined CODE and DATA registers are shown in two intuitive tables; therefore, configuration changes are easily executed to fit specific requirements.


Supports Advanced Controller Specific Syntax

When dealing with advanced controller programming such as variable definition, expression evaluation, branching and looping, the CE interacts with two plugin libraries that recognize special SIEMENS 840D, FANUC Macro B and HEIDENHAIN (ISO/Conversational) controller features. Users also have the option to develop custom plugin DLL modules to drive the CE to meet specific functions.


Run-Time Flexibility

Any NC command blocks can be manually typed or imported as a text file at “Run-Time” using the CE manual data entry (MDI) input console. This feature enables users to test multiple solutions without the need to change the input G-code file and restart the entire process. Users can also edit and save G-code directly.

                                 A CNC Simulator That Allows Verification Inside CATIA

Although Control Emulator is compatible with all major CAD/CAM System, CATIA users may graphically simulate and test NC programs for collisions and over-travel before the G-code is implemented in the production environment. This unique “single workbench” capability allows programmers to avoid and correct programming errors that may have resulted in costly machine tool collisions and defective parts.

In addition, CE accommodates an “in-process” or “on-demand” CATIA/CE simulation environment vs. the existing multiple process loop currently offered by independent competitive

solutions. Benefits include improvements to NC programmer productivity and manufacturing process efficiency.


Technical Details & Specifications

Control Emulator is not a standalone product. It must be integrated with CATIA or ICAM’s Virtual Machine, It requires a 64-bit operating system, minimum 8Gb RAM and any OpenGL compatible graphics card. Minimum OS requirement is Windows XP or more recent.
