Kodėl Digital Twin for Parts Manufacturing?

Detalių gamyboje klaidos atliekant nustatymus, programuojant ar apdirbant gali sukelti brangius susidūrimus, broką ir prastovas. Digital Twin for parts manufacturing leidžia virtualiai patvirtinti mašinas, įrankius, NC programas ir procesus prieš juos vykdant ceche. Imituodami realų mašinos elgesį virtualioje aplinkoje, gamintojai gali patikrinti apdirbimo strategijas, optimizuoti įrankių trajektorijas ir anksti pastebėti problemas. Tai padeda sumažinti fizinių bandymų poreikį, paspartinti paleidimą ir pasiekti gamybą be klaidų iš pirmo karto užtikrinant didesnį pasitikėjimą, efektyvumą bei produktyvumą.

High variability: CNC in a job shop

Small manufacturing shops producing simplified or custom parts often face tight margins and high variability. Programming directly on the machine – without advanced CAM tools – leaves little room for error and increases the risk of crashes, incorrect offsets, or costly downtimes. At the same time, finding qualified personnel, training on various interfaces, and integrating new technology can pose real challenges.

A Digital Twin offers a future-proof solution: it enables NC programs to be developed, tested, and optimized virtually – without interrupting operations. This boosts efficiency, reduces errors, and ensures first-time-right machining even in high-mix, small-batch environments.

Complex workpieces for high-precision manufacturing ​

Manufacturers face growing challenges from precision demands and strict quality standards. Long cycle times, low volumes, and complex, customized parts strain operations. Limited real-time visibility, frequent downtimes, and trial-and-error optimization drive inefficiencies and costs. Ensuring consistent quality and training staff on new tools adds complexity, while mistakes can delay production and lead to costly rework.

A Digital Twin ensures a perfect match between the virtual and real machine - essential for high-precision parts and crash prevention. It enables virtual testing and validation of NC programs created in the CAD environment, enhancing precision, reducing errors, and optimizing operations.

Complex machining operations in a mass production

In high-volume production, every second counts. Complex machining must run efficiently and at scale - without compromising precision. Initial part programming and testing are critical, as errors can lead to delays, waste, and higher costs. High automation levels demand seamless technology integration and well-trained teams to ensure consistency and output.

A Digital Twin simulates and validates the machining process virtually, ensuring accuracy and optimizing parameters before production. This reduces errors, ensures quality standards, and minimizes downtime—ultimately enhancing efficiency and precision in manufacturing. Newly designed tools can also be tested for cycle time reduction.

What is a Digital Twin, and why do you need it?​

A CNC Digital Twin is a digital replica of the entire CNC system, accurately reflecting its control logic, kinematics, and behavior. This digital representation enables comprehensive simulation, analysis, and optimization of the system performance in a virtual environment - any real-world changes are made. It ensures precision from the very first part, reduces downtime, and increases overall efficiency.

Where can you use a Digital Twin in manufacturing?

Digital Twin technology transforms how manufacturers achieve precision, productivity and efficiency. By bridging the digital and the real world, it enables a smarter, more flexible way to prepare, test and improve machining processes – long before manufacturing operations begin.

Virtual job preparation

Machining jobs can be virtually prepared and planned before production begins - including machine setup, tool selection, and parameter definition - all done offline on a PC. Multiple machine twins can be stored on a single computer, allowing NC programs to be created from one workstation. Ready-to-run programs are transferred directly to the real machine, reducing setup time by up to 20%. Users can prepare and test NC programs and train employees even while waiting for new machines - ensuring full readiness when they arrive.

Offline programming and validation

CNC programs can be created and tested offline, without interrupting actual machine operation. NC programs are developed and validated on a PC, allowing testing and optimization to take place entirely in the virtual space. This approach significantly reduces downtime and cuts unproductive machine time by up to 75% - while also improving process reliability and efficiency.

Simulation (basic and advanced)​

Users benefit from both basic and detailed simulation capabilities. Basic simulations quickly reveal potential issues, while advanced simulations offer deeper insights and enable process optimization. By integrating control and kinematics data from VCP files with CAM capabilities, users gain access to a precise simulation environment. This allows them to check manufacturability, assess machine suitability, and accurately calculate production time - without investing in real machines or production capacity.

Training and skill development

Operators can be safely trained on virtual machines, handling various scenarios and programming tasks without risking equipment or interrupting production. Mistakes can be corrected immediately, and training can take place before machines are delivered. This reduces errors, eliminates the need for physical prototypes, and keeps machines available for actual production.
