titled 'CNC Designed for Aerospace Applications'
The Fagor 8065 CNC is designed to provide the high-speed machining necessary for aerospace applications, as well as maintain a quality surface finish and increased accuracy, the company says. The CNC features a 10" or 15" high-resolution, LCD TFT color or touch screen; Ethernet; USB; and a built-in, touch-sensitive mouse pad. It can control as many as 28 axes and four separate spindles with four different execution channels that feature auto-tuning system setup capability.
The CNC features block processing speeds of less than 0.5 ms and analyze the toolpath with high-speed block look-ahead utilizing nano-metric resolution. Combined with adaptive real-time feed and speed control, this enables the CNC to analyze machining conditions, such as spindle load, servo power and tool-tip temperature, and adapt both the axis feed rate and the spindle speed to reduce cycle time and improve part finish.
The aerospace-specific high-speed surface accuracy machining system is said to reduce mechanical stress on the machine to increase tool life and feed rates. Additionally, an on-board Bode diagram tool measures machine frequency response so the machine can filter vibration.
According to the company, aerospace CAD/CAM programs are commonly large and require specific CNC system treatment to maximize speed and precision. To process these programs, the CNC combines splines and polynomial transitions and interprets NURB format that is utilized by CAD/CAM programs. Also, the volumetric compensation feature maps the total work volume so the CNC understands the exact position of the tool at all times, the company says.
Other features include interactive, icon-based pages, conversational programming; an intelligent profile editor, which acts like an on-board, mini-CAD/CAM system; and an on-board graphic editor for custom screens and graphics creation.
