Abstract
Cement or other liquid-like material fills the hollow tubes of a machine tool under construction. The machine tool structures are held rigidly against a fixture while the substance dries. The machine tool so constructed is relatively lightweight and rigid, and obviates the need for precision machining of large portions of the apparatus.
Claims16
A method of fabricating a positioning tool comprising:
- (a) changing a shape of one or more tubes wherein:
- (i) the one or more tubes are hollow, and (ii) the one or more tubes are either pressed against a fixture or constrained from moving in at least one direction by the fixture;
- (b) moving a filler into the one or more tubes while the filler is in a liquid state, wherein the filler solidifies while the one or more tubes are either pressed against the fixture or constrained from moving in at least one direction by the fixture, and (c) aligning at least one shaft in a first set of elongated shafts to be parallel with a first axis, and (d) aligning at least one shaft in a second set of elongated shafts to be parallel with a second axis, the second axis being perpendicular to the first axis;
- wherein, when fabrication of the positioning tool is complete (i) the one or more tubes are structural elements of the positioning tool, (ii) the first set of shafts is configured to guide linear movement of a first carriage, (iii) the second set of shafts is configured to guide linear movement of a second carriage, and (iv) the first and second sets of shafts and the first and second carriages are parts of the positioning tool.
