Abstract

In a machine tool a reference straight-edge is mounted on the worktable of the machine tool and the position of the worktable and therefore the workpiece along the x-axis of the machine is determined by reference to the straight edge; a linear scale is mounted to move with the tool and a reading head associated therewith provides a measure of the position of the tool along the x-axis of the machine, and a linear scale is mounted to move with the worktable and a reading head associated therewith provides a measure of the position of the worktable and therefore the workpiece along the z-axis of the machine; wherein the linear scale mounted to the tool and the reference straight edge mounted to the worktable and the reading heads and sensors associated therewith are all mounted in the same plane, and the machine is mounted so that the said plane is horizontal. The linear tool scale is aligned with the tool axis which intersects the point of application of the tool to the workpiece. The reference straight edge sensor is also located on the same so as to be on the same straight line as the linear tool scale and the point of application of the tool to the workpiece. The reading head for the linear scale mounted to the worktable is also located in the same vertical plane containing the said tool axis. Where the tool is a grinding wheel, the wheel is mounted with its axis of rotation at the same height as the reference straight edge and the linear scale associated with the wheel.
