Human-Machine Interface (HMI) in CNC Press Brakes
Product Description
Human-Machine Interface (HMI) in CNC Press Brakes
The HMI (Human-Machine Interface) is the operator's primary tool for interacting with a CNC press brake. It is typically a touchscreen panel that integrates software to input bending parameters, monitor system status, and control production in real time. A user-friendly and responsive HMI is essential for efficient and safe press brake operations.
✅ Core Functions of Press Brake HMI
Program Input
Operators can enter bending sequences, angles, flange lengths, and material types.Machine Control
Controls key press brake movements: ram position, backgauge, crowning, etc.Real-Time Monitoring
Displays machine status, warnings, errors, stroke cycles, and hydraulic pressures.Alarm Diagnostics
Logs fault codes and system messages, aiding in troubleshooting and maintenance.Tool Management
Supports tool library for upper/lower dies with auto-recognition or manual settings.Remote Connectivity
Modern HMIs support Ethernet, USB, or Wi-Fi for data import/export and remote assistance.
