Document Type and Number:
WIPO Patent Application WO/2009/144845
Kind Code:
A1
Abstract:
Provided are a work attaching table and a machine tool, by which a work can be machined without having the work and a table interfere with a main shaft, even when a plurality of works are attached. A work attaching section (27) having four side surfaces of a square pyramid as work attaching surfaces is fixed to a table (17). A main shaft (19) having a tool (23) mounted thereon and the table (17) can be relatively moved in orthogonally intersecting three axis directions (X, Y, Z), and the table (17) rotates in the directions of axis (A) and axis (C). The rotating angle positions of the axis (A) and axis (C) where the work attaching surface is vertical to the axis line of the main shaft (19) are previously stored in a storage means. At the time of machining a work (33) attached on the work attaching surface, a work coordinate system is set based on the stored rotating anglel positions, and NC machining is performed.
