CNC machining is entering a new era—one defined by speed, precision, and digitalization. Manufacturers are under pressure to boost efficiency, reduce errors, and stay competitive in an increasingly complex production environment. But many are still falling short: disconnected systems, legacy processes, and manual validation continue to limit performance.
Enter the comprehensive Digital Twin—a powerful way to bridge the gap between digital-world programming and real-world machining. Whether you’re running a flexible job shop or a high-precision manufacturing operation, the comprehensive Digital Twin gives you the tools to optimize processes, reduce risk, and make better parts—faster.
Closing the digital gap in CNC machining
According to recent surveys, only 10% of global manufacturers have fully completed their digital transformation. Many are stuck in pilot phases or using siloed systems for CAD, CAM, and data management. Over 50% still rely on standalone CAD/CAM systems, and 75% of part inspections are disconnected from the rest of the workflow. This fragmentation leads to inefficiencies, manual errors, and production delays.
The Digital Twin closes these gaps. It enables manufacturers to simulate, test, and optimize every step of the machining process before cutting begins—minimizing downtime, waste, and costly mistakes.
Two worlds, one solution
CNC machining varies widely—from job shops with high part turnover to industries like aerospace and automotive, where precision and compliance are non-negotiable. Siemens’ Digital Twin solutions adapt to both worlds:
1. Job shops: Speed with confidence
Job shops operate fast, often programming directly at the machine. This allows for flexibility but increases the risk of setup errors, tool issues, and programming faults. Dry runs and manual validations consume time and reduce machine utilization.
Run MyVirtual Machine (RMVM) mirrors the real SINUMERIK ONE CNC interface, allowing operators to test programs virtually before touching the real machine. This minimizes rework, increases confidence, and frees up machines for production. Virtual training also helps onboard new operators quickly and safely—without disrupting shop floor activity.
2. High-precision manufacturing: Accuracy without compromise
Industries like aerospace and medical device manufacturing depend on perfect repeatability and strict compliance. A single error can mean thousands of dollars in wasted material. Here, Siemens’ NX CAM-integrated Digital Twin ensures that every part is perfectly simulated before production begins.
Turbine blades, carbon composites, and titanium parts can be modeled, programmed, and validated virtually—ensuring optimized toolpaths and precision cutting conditions. The result? Less waste, higher productivity, and faster time to market.
From digital to real, seamlessly
Siemens’ Digital Twin ecosystem provides new methodologies to overcome typical CNC challenges:
- Run MyVirtual Machine: Simulates real NC code and controller behavior, reducing programming errors and setup time.
- Protect MyMachine /3D Twin: Provides real-time collision prevention during actual machining, stopping operations before damage occurs.
- Analyze MyWorkpiece /Toolpath: Compares real and virtual toolpaths, helping engineers optimize cutting strategies for even better performance.
Together, these tools form a closed feedback loop—from programming to production to improvement—helping companies continuously refine their processes.
Tailored to your workflow
Siemens offers two Digital Twin paths: One is machine-oriented, perfect for programming directly at the CNC, enabling realistic simulation, training, and testing offline. The other is workpiece-oriented, ideal for CAM-based workflows, enabling high-fidelity simulation of complex parts and integration with NX CAM and third-party tools. Whichever approach you use, Siemens ensures that your virtual validations reflect the real machining environment—down to the kinematics and controller behavior.
