We have a pentium based pc that is used to control the elongation of the actuator, a Power Amplifier to provide the necessary current to the actuator, and a compliment of sensors, including: Load Cells, Acceleromenters, a displacement sensor, and other equipment. The total actuation system has a bandwidth of 1.8 kHz.
Here is a picture of the actuator in operation. The material being cut is an aluminum alloy. The actuator/flexor system is mounted to the tool holder turret of MTU's CNC lathe. We hope to have a video soon....better wear your safety glasses!!
