Abstract
A carriage is moved in a direction including a Y axis component in order to move a turning process tool that is attached to a tool spindle along a horizontal line that is perpendicular to a Z axis, and thus, a turning process is carried out on a workpiece which is attached to a workpiece spindle.
Claims7
A method for controlling a combined lathe apparatus, wherein the combined lathe apparatus comprises:
- a workpiece spindle on which a workpiece is mounted, the workpiece spindle having a first axis;
- a tool spindle to which a turning process tool for carrying out a turning process on the workpiece is removably attached;
- an automatic tool replacing device to take out a specific turning process tool from among a plurality of turning process tools and to replace 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 the first axis of the workpiece spindle and forms a predetermined angle with a horizontal plane, wherein the predetermined angle is greater than zero degrees and less than or equal to ninety degrees, wherein the tool spindle forms a portion of the tool headstock;
- and
- a movable body which supports the tool headstock;
- wherein the movable body is movable in a direction including a third axis component which is perpendicular to the first axis and the second axis;
- wherein the tool spindle is controlled to be rotated or held without being rotated;
- and
- wherein a cutting point of the specific turning process tool attached to the tool spindle is moved along a horizontal line which is perpendicular to the first axis by moving the movable body in the direction including the third axis component.
