Structure for moving tools in numeric control machines for the working of rigid and semirigid planar materials

Abstract

A structure (1) for moving tools in numeric control machines for the working of rigid and semirigid planar materials, comprising a supporting framework (3) adapted to be arranged in a position that lies above a working surface of a numeric control machine, the supporting framework (3) supporting at least one arm (15) for supporting a tool head (2), the arm (15) being movable along a bridge (10), the tool head (2) supporting at least one tool, there being also means for compensating vibrations and / or oscillations that are a consequence of the accelerations caused by the movement of the at leastone tool head (2), the compensation means (9) being movable along the bridge (10), on a plane that is parallel to the movement plane of the at least one tool head (2).

Description

technical field [0001] The present invention relates to structures for moving tools in numerically controlled machine tools for machining rigid and semi-rigid planar materials. Background technique [0002] It is well known that CNC machine tool tools for cutting and other processing of rigid and semi-rigid planar materials such as sheets of plastic materials, cellulosic materials, textile materials or natural leather are widely available commercially Moving along the XY plane on which the material to be machined is arranged, one or more toolheads are provided with means for cutting, shearing, marking, etc. [0003] The tool head moves on the XY plane along the machining path required according to the logic of the highest possible efficiency in terms of the capacity and quality of the machining performed. [0004] The tool head is moved by a support carriage which moves laterally relative to a support structure which may be fixed or movable relative to the machined surface ...

AI Technical Summary

Problems solved by technology

[0006] If one wishes to increase machining performance, one obtains the undesired effects of vibrations and / or oscillations, in addition to possible damage to other parts and instruments present on the machine tool as well as complicating the interaction of the operator in the machining area during the machining activity of the tool In addition, this impairs the correct execution of the machining (due to the relative displacement between the axis system and the machined surface)
