CNC system for aerospace machining

Designed for the aerospace market, 8060/8065 CNC platforms include advanced features for high-speed machining while maintaining high surface finish and accuracy.

Offered with a 10" or 15" color or touch screen, Ethernet, USB, and a touch-sensitive mouse pad, the 8065 CNC platform can control up to 28 axes plus four separate spindles with four execution channels and auto-tuning system capability. The 8065 includes block processing speeds of <0.5ms while analyzing the tool path with high-speed block look-ahead using nanometric resolution. Combined with adaptive real-time feed and speed (ARFS) control, the CNC analyzes machining conditions – spindle load, servo power, and tool tip temperature – and adapts both the axis feed rate and the spindle speed for maximum machining performance. Results include reduced cycle time, consistent part finish, extended spindle and servo motor life, and improved tool utilization.

The aerospace-specific high-speed surface accuracy (HSSA) machining system reduces mechanical stress on the machine, increasing its lifespan. An onboard Bode diagram tool measures the machine’s frequency response and allows filtering of machine vibrations.

It processes CAD/CAM programs that use splines and polynomial transitions and interprets the NURB format to achieve high feed-rate machining.

The system can interface with Renishaw Inspection Plus software, which includes vector and angle measure options, print options, and an extended range of cycles. These options include an SPC cycle, 1- or 2-touch probing option, tool offset compensation by percentage of error, and output data stored in an accessible variable stack.

Using its volumetric compensation (FVC) feature, the 8065 maps the machine’s total work volume, ensuring the CNC understands the exact position of the tool at all times. Benefits include a 50% improvement in accuracy, and machine-to-machine uniformed accuracy improvements.

All 8060/8065 platforms are capable of using MT Connect for retrieval of process information. Its open protocol allows easy data exchange between shop floor equipment and monitoring and data analysis software. Ethernet communication lets the 8065 serve as another node in the computer network to facilitate data exchange or to execute programs residing on another PC.

Interactive Icon-based Pages (IIP) conversational programming allows operators to use an icon key to choose the operation. Operators enter data directly from the blueprint; no prior CNC programming experience is required. A single screen eliminates shuffling through screen pages to input machining-variable data.
