Abstract
A two way roundness device can be configured as a device in which a tool, such as an indicator rotates or as a device in which the part to be measured or cut rotates. This ability to alternate between these two configurations is enabled by a combination of a rotating spindle assembly and a two-axis stage that can be oriented, in use, with the two-axis stage under the spindle assembly or with the two-axis stage on top of the spindle assembly.
Claims20
A two way roundness device operable in two different configurations comprising:
- a two-axis stage, movable in two perpendicular directions and having a first side with a planar portion sufficient to support the two-way roundness device when the first side is resting on a flat surface, the planar portion being parallel to the two directions of movement;
- a spindle assembly attached to the two-axis stage in the center of a second side opposite the first side, the spindle assembly being rotatable about longitudinal axis of rotation perpendicular to the two directions of movement of the two axis stage;
- and
- an arm having a tool receiving portion and being attachable to the spindle assembly, whereby, in a first configuration, the two way roundness device is operable with the spindle oriented above the first side, with the arm attached to the spindle and the spindle assembly being rotatable;
- and
- in a second configuration, the two way roundness device is operable with the first side oriented above the spindle assembly and the two-axis stage being rotatable.
