Growing Business automatically optimize the functions of the machine tool during the machining process, avoiding mistakes and adapting to changing tool and temperature conditions. Te result is consistently good production and avoidance of scrap and nice capability, especially when considering the cost of material from tool steel to aerospace alloys. Te ability to tune the machine tool on the fy for the application would be a tremendous advantage for any turning shop. Consider a secondary operation that requires roughing, semi-fnishing and fnishing on one machine. Te ability to tune the machine's behavior through the part program can dramatically support precision across the entire program while improving throughput. It is easy to use these features: Tey run in the background using simple input of data by the programmer, including tool application recommendations by the cutting tool manufacturers. Programmers can tune the drive system to perform acc/dec appropriate to the roughing, then back it of for fnishing. Trough G-code commands, the speeds and feeds in the process can match the requirements of any programmed operation. Trough sensors in the machine, this type of machining software monitors variables related to the work environment and machining conditions, including speeds, pressures and temperatures. Tese highly sensitive thermal sensors mounted at various locations in the machine castings where thermal displacement is possible permit software monitoring and correction of detected thermal displacement within milliseconds. In every machine, heat is generated in a machine structure by continuous movement of each axis, changing the geometry of the machine frame, thus afecting the tool center point location. Frame displacement control monitors temperature at several points on the machine, automatically minimizing the displacement of the frame caused by any variation in temperature within real-time. Most shops do not have closely controlled ambient temperature, so this type of control would be essential for consistent precision machining. Tool load detection software provides real-time measurement of tool load, ensuring consistent and safe machining. Constantly monitoring tool loads, which can cause tool damage and deterioration for prevention of complete tool failure, this software supports accuracy and performance. Such a system will measure tool load frequently, such as every few milliseconds; as the tool wears, the spindle load increases rapidly. A contour control system ofers an easy-to-use programming interface, which provides a precise, custom contour control for the selected workpiece while supporting long machine life and reduced process time. Such software will ofer diferent options for cutting speed :: Precision vertical machining centers, such as this Hwacheon Vesta, are designed for thermal and geometric stability. Internal sensing and sophisticated programming routines allow these machines to run virtually autonomously. productionmachining.com :: 35
