Machine tool

A machine tool, comprising:

• a bed;
• a column extending upward from the bed;
• a support member configured to be movable in an upper-lower direction with respect to the column;
• a table configured to be movable with respect to the support member;
• a cutting unit being supported by the support member and including a spindle on which a cutting tool is mounted wherein the cutting tool is configured to carry out a cutting process on an object to be machined that is supported on the table;
• a turning unit being supported by the support member and on which a lathe machining tool is mounted wherein the lathe machining tool is configured to carry out a turning process on the object to be machined that is supported on the table;
• a relative movement mechanism configured to cause the table to move relative to the support member;
• a movement control unit configured to control the relative movement mechanism;
• a relative position detection unit configured to detect a relative position of the table with respect to the support member;
• and
• a distance calculation unit configured to calculate a distance between the cutting unit and the turning unit, based on the relative position when cutting unit and the table have arrived at a first relative positional relationship, and the relative position when the turning unit and the table have arrived at a second relative positional relationship.
