Groove cutting innovation
For 25 years, Linde Co., Ltd. has been a leader in the design and manufacturing of rotating equipment, specializing in flame and plasma cutting solutions. Their innovative rotating devices are widely used by other manufacturers, allowing for precise cuts at ±45° angles. Automated plasma bevel cutting demands advanced CNC systems due to the complexity of maintaining consistent cut quality. Standard components often fall short when it comes to adjusting the height of the cutting head, which is crucial for achieving accurate bevels.
Plasma cutting differs from laser cutting in that the plasma beam travels at supersonic speeds, slower than light. This can lead to delays if the cutting head moves too quickly, affecting accuracy if parameters aren't properly set. During the process, gas is ionized between the nozzle (cathode) and the workpiece (anode), generating temperatures up to 30,000°C, which vaporizes metal instantly. However, this intense heat can cause melting at corners or edges, especially when cutting square shapes, resulting in waste or defects.
Magnetization and inertia also impact cut quality. While these effects can't be entirely eliminated, advanced control technologies help minimize their influence. Key areas of adjustment include torch height, cutting speed, and slit offset. For bevel cutting, proper torch spacing compensation is essential.
Linde recently introduced the "KingP4500" CNC universal cutting machine, integrating plasma, flame, drilling, milling, and punching into one platform using Aikeman’s CNC technology. The front features a plasma rotating device for bevel cutting, while the rear houses a drill collar and pin marking unit. The machine moves via a gantry axis and includes a tool changer and a tool length measuring probe.
This integration streamlines production, reduces setup time, and lowers costs. It also allows manufacturers to focus on their core competencies while relying on automation experts for complex control systems. Aikeman Group, with over 50 years of experience in electronic control systems, provides tailored solutions for CNC applications, particularly in cutting technology.
Perfect groove cutting requires precise adjustments. Plasma nozzles must maintain optimal height and angle, which is challenging when cutting grooves. By scanning the workpiece surface beforehand, the CNC system can adjust the Z-axis in real-time. The B-axis angle further aids in online height compensation. Flame units use capacitive height adjustment, fixed to the Y-axis.
Intelligent control systems play a key role in compensating for physical limitations. Linde's machines use internal compensation tables for tilt axis position, cutting speed, slit offset, and torch distance. These tables are easily accessible and adjustable, allowing operators to add work points as needed. This improves accuracy, especially during complex bevel cuts.
Linde uses "PROfi rst CAM" software, enhanced by Aikeman’s preprocessor to embed control-specific commands. This ensures the CNC system operates independently from the CAD/CAM software. The preprocessor also manages tool selection and scanning cycles, improving efficiency and reducing errors.
Aikeman’s NC operating system supports functions like Z-adjustment, tangential tool reset, path-dependent speed control, and nested conversion. These features ensure high-quality cuts and seamless operation.
