Abstract
An assembly for carrying a measuring gauge to be maintained in contact with a portion of a workpiece mounted in a machine tool arranged to rotate the workpiece about a machine reference axis. The assembly is for mounting on a carriage shared with a material removing tool and comprises a slide which is slidable in the direction of infeed of said material removing tool. A mount coupling is pivotally coupled to the slide by a pivot and is arranged to accommodate variation of the spacing between the mount and the pivot due to the rotary motion of said workpiece portion. A slide driver is arranged to reciprocate the slide relative to the slide support in synchronism with the rotation of said workpiece portion. An associated method is also provided.
Claims31
An assembly for carrying a measuring gauge to be maintained in contact with a portion of a workpiece mounted in a machine tool arranged to rotate the workpiece about a machine reference axis, the portion of the workpiece following an orbital path around said machine reference axis as the workpiece rotates, wherein the assembly is for mounting on a carriage shared with a material removing tool of said machine tool and comprises:
- a slide support;
- a slide which is mounted on the slide support so as to be slidable with respect to the slide support and the material removing tool along a linear axis, the linear axis being parallel in use to the direction of infeed of said material removing tool;
- a mount for connection to said measuring gauge;
- a mount coupling which couples the mount to the slide, is pivotally mounted on the slide by a pivot and is arranged to accommodate variation of the spacing between the mount and the pivot due to the orbital motion of said workpiece portion;
- and
- a slide driver arranged to reciprocate the slide relative to the slide support in synchronism with the orbital motion of said workpiece portion.

A method for maintaining a measuring gauge in engagement with a portion of a workpiece following an orbital path in a machine tool about a machine reference axis as the workpiece is rotated by the machine tool, the machine tool including a material removing tool, and the method comprising the steps of:
- providing an assembly carrying the measuring gauge, the assembly including a slide which is mounted on a slide support so as to be slidable with respect to the slide support and the material removing tool along a linear reference axis, a mount connected to the measuring gauge, and a mount coupling which couples the mount to the slide, is pivotally mounted on the slide by a pivot and is arranged to accommodate variation in the spacing between the mount and the pivot due to said orbital motion of the workpiece portion;
- mounting the assembly on a carriage shared with the material removing tool of the machine tool, with the linear reference axis of the slide parallel to the direction of infeed of the material removing tool;
- arranging the assembly such that the measuring gauge is in engagement with the portion of the workpiece;
- rotating the workpiece about the machine reference axis;
- and
- reciprocating the slide relative to the slide support substantially in synchronism with the orbital motion of said workpiece portion about the machine reference axis, with the assembly accommodating changes in the location of the measuring gauge relative to the slide support so as to maintain the measuring gauge in engagement with the portion of the workpiece.
