Measuring System

The measuring system is a critical component of aluminum profile cutting machines, responsible for accurately determining the required cutting length of aluminum profiles before the cutting operation. It ensures dimensional accuracy by measuring the profile length against programmed specifications, often using sensors, encoders, or laser measurement devices to detect the profile position and trigger the cutting mechanism at precise locations. This subsystem is designed for integration into CNC-controlled cutting systems, providing real-time feedback to the controller. The measuring range is customizable up to 6000 mm, with a resolution of 0.01 mm, ensuring high precision for positioning. Accuracy is ±0.05 mm (including linear guide errors) and repeatability is ±0.02 mm for consecutive cuts, both referenced to ISO 230-2. Measuring speed is adjustable between 10 and 60 m/min, depending on material type. The system operates within a temperature range of -10°C to 50°C, with storage from -20°C to 70°C, and relative humidity of 10% to 90% (non-condensing). Ingress protection is rated IP54 to IP65 per IEC 60529, suitable for dusty environments. Supply voltage is 24 V DC ±10%, with power consumption between 15 and 30 W depending on encoder type. Output signals are TTL/HTL, compatible with CNC controllers. The standard measuring unit weighs between 2.5 and 5.0 kg. Materials used include stainless steel, aluminum alloy, optical glass, and electronic components.

The measuring system typically operates using a combination of mechanical contact sensors, optical encoders, or laser distance sensors. As the aluminum profile is fed through the machine, the measuring system tracks its movement. When the programmed cutting length is reached, the system sends a signal to the cutting unit to execute the cut. Some advanced systems use non-contact laser measurement for higher precision and to avoid surface damage. The system interfaces with CNC controllers via TTL/HTL signals, enabling precise positioning and repeatable cuts.
