Problems solved by technology

[0004] As is well known, this not only determines the deformation of the spindle or drill rod of the machine tool (thus necessitating the use of compensation systems), but also determines the deformation, thus being another cause of inaccuracies in machining operations

Embodiment Construction

[0018] Referring to the drawings, reference numeral 1 generally designates a machine tool, for example a milling-boring machine tool of large dimensions, comprising a bed 2 having a main extension along a main axis X.

[0019] The pedestal 2 is secured and placed on a base F and the support surface defines a horizontal work surface plane T.

[0020] The machine tool 1 also comprises an upright base 4 mounted atop and supported by the pedestal 2 , said base being controllably translatable along the main axis X . For example, the machine tool 1 comprises control means for the translation of the upright base operatively connected with the associated machinery to control the controlled translation of the upright base 4 .

[0021] The machine tool 1 also comprises an upright part 6 fastened to and supported by an upright base 4, said upright part having a main extension along a vertical axis Y relative to the working Face plane T is at right angles. The upright 6 preferably has a...

Abstract

A machine tool, such as a large-sized machine tool, comprising: a pedestal (2), an upright base (4), a control device for translation of the upright base, including an optical line or linear encoder (20) fixed to the pedestal (2) ), means for detecting the temperature (TI..., Tn) of said optical line, and for processing temperature signals from said optical line temperature detection means and signals from said upright base translation control means management means (30) to determine a correction signal for said upright base translation control means based on detecting at least one temperature along said optical line.

Description

technical field [0001] The subject of the invention is a machine tool, in particular a machine tool of large size, having a device for detecting and compensating thermal deformations of the measuring tool of said machine. Background technique [0002] High-precision machining operations on media and large-sized machine parts are highly desirable in working environments where temperature and humidity are not controlled, such as large workshops located in cold or humid areas where temperatures Drops well below 15°C, with huge heat swings between day and night. [0003] In such working environments, it often happens (even during machine operation) that the workpiece to be machined and the support on which it is mounted, separated from said machine tool, are cold (as is the surrounding environment), Instead, the components of the machine tool tend to heat up. [0004] As is well known, this not only determines the deformation of the spindle or drill rod of the machine tool (th...
