SHEFFIELD, UK, Dec 5, 2025 – MachineWorks and Hwacheon integrated MachineWorks’ CNC simulation and verification libraries into Hwacheon’s Harmony smart control, giving the control built-in toolpath verification and machining-accuracy checks. The Harmony interface uses a 19-inch TFT LED touchscreen and is built for intuitive ‘smartphone’-like operation.
Hwacheon has developed control software since 2012, and the core functions in its system have been tested in production for more than a decade. The company launched the Harmony series in the US in 2022, and the newest version introduces improvements to the control software architecture.
The control comes with features as standard including conversational programming work scheduling, probing support, toolpath optimization and the advanced, real-time, collision avoidance system based on MachineWorks.
H-Simul provides simulation-based functionality for 3-axis and 5-axis milling along with multi-turret mill-turn lathes and machining centers, including:
- G-code based simulation
- Automatic registration and generation of materials from CAD data
- Easy setup of fixtures from external files
- Generation of hexagon and column fixtures
- Full machine collision checking using MachineWorks’ sweep-based collision check
- Undercut (rest) and overcut (gouge) detection
- Accurate, stable and performant simulation
H-Opti provides a range of toolpath optimization strategies, including:
- Feed rate optimization based on cutting amounts, preventing tool damage and extending the tool’s lifetime
- Adjustments for overloaded and underloaded regions
- Rapid feed collision detection and correction
- Undercut (rest) and overcut (gouge) detection
The new control is standard on Hwacheon’s i2 multi-tasking machine and the M1-5AX five-axis machining center. Hwacheon expects to add the control to additional models over time.
“Hwacheon prides itself on delivering high quality, high accuracy products. After testing many systems, we found the material removal and collision detection algorithms in the MachineWorks libraries to be the most advanced available on the market. Their team of geometry experts are responsive, knowledgeable and available to help, and it has been a pleasure to work with them,” commented Daeyu Park, the director of Hwacheon’s software R&D center.
Dr Fenqiang Lin, the managing director of MachineWorks said: “Hwacheon’s new HMI looks really great. Hwacheon and MachineWorks have been working as partners for over a decade now. MachineWorks is proud to support Hwacheon as it brings new and advanced innovations that will improve the competitiveness of their customer’s businesses.”
