Title:
REMOTE CONTROL ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2010/061567
Kind Code:
A1
Abstract:
Disclosed is a remote control actuator which is capable of changing the posture of a tool provided on the tip of a narrow pipe part by remote control and is capable of processing with optimal processing conditions at all times. The actuator is equipped with: a spindle guide unit (3) having a long, slender shape; a tip member (2) which is attached on the tip of the spindle guide unit in a manner such that the posture can be changed freely and rotatably supports a tool; and a drive unit housing (4a) to which the base end of the spindle guide unit (3) is connected. The interior of the spindle guide unit (3) is provided with a rotary shaft (22) which transfers to the tool the rotation of a tool rotation drive source (41) in the drive unit housing (4a), and a posture manipulation member (31) which changes the posture of the tip member by driving a posture change drive source (42) in the drive unit housing (4a). A cutting force estimation means (6) is provided to estimate the size of at least one component force of the feed force (Pf), the thrust force (Fr), and the primary force (Fc), of the cutting force applied by the tool to the object being processed.
