Patent ID: 8650729

Claim:
A blade position registering apparatus for registering a position of a blade of a turning process tool which is provided in a combined lathe apparatus, wherein the combined lathe apparatus comprises: a workpiece spindle on which a workpiece is mounted; a tool spindle to which a turning process tool for carrying out a turning process on the workpiece is removably attached; automatic tool replacing means for taking out a specific turning process tool from among a plurality of turning process tools and replacing the turning process tool attached to the tool spindle with the specific turning process tool; a tool headstock which is movable along a second axis which is perpendicular to a first axis, which corresponds with a longitudinal axis of the workpiece spindle, and the second axis positioned a predetermined angle with a horizontal plane, the tool headstock also having the tool spindle; a movable body which supports the tool headstock; a control means for controlling movement of the movable body; wherein the movable body is movable in a direction including a component of a third axis, which is perpendicular to the first axis, wherein the component of the third axis is parallel to the horizontal plane, wherein the tool spindle can be controlled to be rotated or held without being rotated, and wherein the control means moves a cutting point of the turning process tool attached to the tool spindle along a horizontal line, which is perpendicular to the first axis, by moving the movable body in a direction along the component of the third axis during a turning process on the workpiece attached to the workpiece spindle, wherein a reference point is provided on the axis of the tool spindle; the blade position registering apparatus comprising: a blade position inputting means for inputting 1) a first tool length, which is an amount of offset by which the blade of the turning process tool is offset from the reference point along the first axis, 2) a second tool length which is an amount of offset by which the blade of the turning process tool is offset from the reference point along a second horizontal line, which is perpendicular to the first axis, 3) a third tool length, which is an amount of offset by which the blade of the turning process tool is offset from the reference point along a vertical line, 4) a fourth tool length, which is an amount of offset by which a blade of a second tool that does not cut in the horizontal line for turning in a second axis-first axis plane is offset from the reference point along the first axis, and 5) a fifth tool length, which is an amount of offset by which the blade of the second tool for turning in the second axis-first axis plane is offset from the reference point along the second axis, and a storage means for storing the inputted first tool length, the second tool length, the third tool length, the fourth tool length, and the fifth tool length.
