Abstract
The method can include: assembling the part to be machined to a pallet into an assembly; measuring a centering of the part relative to the pallet; adjusting the centering of the part relative to the pallet based on said measuring; repeating the steps of measuring and adjusting until determining that the part is centered based on said measuring; and mounting the centered assembly to an automatic machining device and machining the part of the centered assembly with the automatic machining device.
Claims14
A method of machining a part, the method comprising:
- assembling the part to be machined to a pallet to form an assembly;
- prior to mounting the assembly to an automatic machine tool,
- rotating the assembly at a set-up station separate from the automatic machine tool,
- while rotating the assembly, measuring at the set-up station a centering of the part relative to a center axis of the pallet by comparing variations of movement of a reference point of the pallet with variations of movement of a reference point of the part, and
- based on said measuring, pre-centering the part in a coordinate system of the automatic machine tool by adjusting at the set-up station the centering of the part relative to the center axis of the pallet;
- and
- mounting the centered assembly to the automatic machine tool and machining the mounted part with the automatic machine tool.
A method of machining a part, the method comprising:
- assembling the part to be machined to a pallet to form an assembly;
- prior to mounting the assembly to an automatic machining device,
- mounting the assembly to a rotary chuck,
- measuring, at a set-up station separate from the automatic machine tool, a centering of the part relative to a center axis of the pallet by rotating the assembly on the rotary chuck and monitoring a relative run-out between the part and the pallet while rotating the assembly,
- pre-centering the part in a coordinate system of the automatic machine tool by adjusting, at the set-up station, the centering of the part relative to the center axis of the pallet based on said measuring, and
- repeating the steps of measuring and adjusting until determining that the part is centered based on said measuring;
- and
- mounting the centered assembly to the automatic machining device and machining the part of the centered assembly with the automatic machining device.
