Vein technology allows for a large variation in tool geometry that was impossible to achieve with the conventional PCD- bit process. The PCD-vein drill is typically engineered for a solution which is part of an automated setup for optimizing performance and hole-quality consistency when drilling a CFRP. Part of its unique edge may include strengthened tool corners for higher cutting speeds, combined with the ability to maintain tight entry and exit limits.
The PCD-vein drill can also be engineered for CFRP stacked with metals. It can then be provided with micro-grinds placed to cope with concentrated areas of high stress. This provides the drill with even more ability to remain sharp and exact throughout a long tool life. The edge of the drill cuts CFRP fibers at low thrust, resulting in minimal fiber breakout, delamination and burrs when exiting the stacked metal.

Advanced Software Smooths HSM Motion
urco’s VMXHSi series high-speed machining centers are equipped with UltiMotion motion control system that uses complex software algorithms for motion planning instead of conventional hardware. The software is more efficient in how it processes motion so there is less chatter, less vibration, and less machine jerk, which results in better surface finish and reduces cycle time by as much as 35%. The software-based motion con- trol system has rapid cornering capabilities, allowing it to travel through blended corners at high speed with negligible deviation. With UltiMotion, the software evaluates each section of the motion profile and shifts the look-ahead to the maximum number of blocks to optimize maneuvers. For example, with drilling and tapping, instead of the jolting down/up/stop motion of conventional motion controls systems that use hard- ware, UltiMotion keeps the motion smooth and is able to use a spherical motion to move to the next set of holes. The Hurco integrated control has the memory and processing power to handle the advanced toolpaths generated by CAM systems. The control is optimized for HSM with a 64 GB solid-state drive, 2 GB of memory, a 2-GHz Dual Core Intel Processor, processing speed to 2277 bps and Dynamic Variable Look- Ahead capable of up to 10,000 blocks.
