A multifunctional end effector includes a support structure configured to be carried by a robotic system and at least two of a fluid stream cutting system, a spindle system and/or a scanning system, each mounted to the support structure. Also described is a fluid stream cutting system having a plurality of fluid stream catchers selectively mountable to the fluid stream system and a mounting arrangement for mounting each fluid stream catcher to the fluid stream cutting system.

A non-Cartesian coordinate positioning machine is provided that comprises an extendable leg assembly for positioning a component such as a measurement probe within a working volume of the machine, and a constraint member associated with the extendable leg assembly for providing a predetermined part of the extendable leg assembly with substantially a same orientation relative to gravity for a same position of the component within the working volume. In a preferred embodiment, the orientation relative to gravity is maintained substantially constant, so that a plane defined by the predetermined part is substantially aligned with gravity, as the component is moved around the working volume.

A work-piece transfer apparatus, comprising at least one work-piece engagement structure; at least one first robot arm pivotally connected to the work-piece engagement structure; a first motor coupled to the first robot arm and being adapted for translating the first robot arm fore and aft in a generally horizontal direction; a second motor, at least one second robot arm being in operating driving relationship with the second motor and operatively coupled with the work-piece engagement structure for raising and lowering the work-piece engagement structure; and a support structure for supporting the apparatus or portions thereof; wherein the first motor and second motor are operated synchronously to raise, lower, and/or translate the work-piece engagement structure in a fore and aft direction by way of one or both of the first robot arm and second robot arm.

A machine tool for machining a workpiece has a spindle arm with a spindle for receiving a tool or workpiece. The spindle arm is movably attached to a spindle arm receiving section. The spindle arm has a first spindle arm section, being a longitudinal element, having a first rotational axis with respect to the spindle arm receiving section and is hinged to the spindle arm receiving section; a second spindle arm section, rotatable about a second rotational axis with respect to and is hinged to the first. The spindle arm receiving section has a first subsection and a second subsection, arranged on the machine column at a distance from one another to receive the spindle arm. The first spindle arm section has first and second subsections, which are arranged on the spindle arm receiving section at a distance from each other to receive the second spindle arm section.

The technology disclosed in the present disclosure is a method for correcting a yaw of an X-Y stage, including: moving an XY moving body in an X-axis or Y-axis direction using an actuator; measuring a yaw, which is a rotational displacement of the moved XY moving body, using a sensor; calculating, by a controller, a rotational stiffness value to be corrected, using the measured yaw data; and adding yaw correction flexures having a stiffness corresponding to the rotational stiffness value to be corrected to the X-Y stage.

This machine tool is provided with: a bridge which is provided on a base in such a way as to straddle a moving body in a direction (X) perpendicular to a direction of movement (Z) of the moving body at a stroke end (E2) of the moving body; a pallet exchanging arm which is provided above the bridge and which engages with a pallet (P) supported on the moving body and a pallet (P) on a pallet loading station, lifts both pallets (P), and pivots about a vertical axis (Ov) to exchange the two pallets (P); and an arm drive device which is provided projecting upward on the bridge, and which moves the pallet exchanging arm along the vertical axis (Ov) and causes the pallet exchanging arm to pivot about the vertical axis (Ov).

A three-axis tool head unit for a machine tool spindle, which comprises three components, which are rotatable or pivotable relative to each other about independent axes. A first head part is rotatably mounted on a support arm about a first axis with respect to the support arm. A second head part is rotatably mounted on the first head part about a second axis with respect to the first head part. A spindle device is rotatably mounted on the second head part about a third axis with respect to the second head part. The third rotary axis is oriented orthogonally to the first and the second rotary axes, while the first and the second rotary axes are inclined relative to each other. Each of the three rotary axes has an associated individual drive device for driving and controlling the rotation of the component about its respective axis.
