A method for cutting machining of turbine blades (1) on a multi-axis machine tool, the turbine blade (1) is held by a rotatable blade-root clamping device and a rotatable blade-tip clamping device (2) and is machined by means of a tool which is chucked in a tool spindle. A first profile section (4) which is adjacent to the blade tip is first of all machined by the tool and the tool is then removed. The tool spindle then grabs an already horizontal additional clamping device (5) which has clamping jaws (6.1, 6.2) adapted to the first profile section (4). The additional clamping device (5) is positioned on the blade-tip clamping device (2) in such a way that the clamping jaws (6.1, 6.2) rest in the first profile section (4). The tool spindle then grabs a tool and machines the remaining profile section with it.

An apparatus for lifting and rotating a frame of a motor vehicle includes a rotisserie and a rotatably connected fixture that holds the motor vehicle frame during production. The fixture includes clamps extending from arms of the fixture and clamps extending from the front support for affixing the frame of the motor vehicle to the fixture. The fixture may further include a passive lock mechanism for engaging a side sill of the frame that includes a latch, a locking extension, a latch spring that holds the latch in engagement with the frame, and a pendulum that rotates relative to the fixture but remains oriented in a fixed location relative to horizontal. The latch may only be disengaged from the frame when the locking extension is aligned to be received by a slot in the pendulum when the fixture is rotated to the home location.

The present invention proposes an in-situ freezing machining method for an integrated thin-walled array structure. In the method, the area among cups is cut off first; then, the outer walls of a cup array are machined; and finally, water filling and freezing are carried out, and in-situ freezing machining of the inner walls of the cup array is carried out. Then, hoisting and turning over are carried out, and the area among cavities is cut off; then, the outer walls of a cavity array are machined; and finally, water filling and freezing are carried out, and in-situ freezing machining of the inner walls of the cavity array is carried out. The method realizes in-situ freezing clamping of workpieces, avoids error accumulation caused by repeated installation of a fixture, and can refrigerate efficiently, suppress ambient and cutting thermal interference, and ensure the stability of freezing fixture.
