High-speed wire electrochemical-discharge cutting method (HS-WECDM), in which a work piece is processed by means of a wire electrode, in which consecutive negative polarity pulses are applied at said wire electrode, thereby at least partially developing discrete electrical discharges, wherein the method further includes, applying positive polarity pulses at the wire electrode between the negative pulses, and that an ignition occurring with each positive polarity pulse is immediately detected, and that the positive polarity pulses are immediately interrupted.

Method for high-speed wire cutting

The present invention is directed to a method for mitigation of the damages in case of accidental collisions in a machine tool comprising a computer numerical control (CNC) and a plurality of axes, wherein the occurrence of collisions is monitored, comprises: identifying a first axis being an axis at which a collision is first detected, identifying a second axis being an axis parallel to said first axis, and determining if both or one or none of the axes are resting. If both are resting unlocking the first axis or both axes. If the first axis or second axis is not resting, then the moving axis is defined as the collider, and said moving axis is braked, and simultaneously the resting axis is unlocked or stepped away or held in position. If both axes are moving, defining a collider axis based on said identified first axis at which a collision has been first detected, braking said collider axis and simultaneously unlocking or stepping away the axis parallel to said collider axis.

Collision protection method in a machine tool comprising a computer numerical control

A linear shaft motor () has a slider () and a tubular magnetic shaft (). The slider () includes an oblong cuboid shaped motor housing () having a rectangular cross-section with a longitudinal central bore (). The motor housing () includes at least two longitudinal cooling holes () which are part of an integrated fluid cooling circuit. The at least two longitudinal cooling holes (-) are distributed symmetrically at a left and at a right side of the central bore (), whereas the central axis () of any of the longitudinal cooling holes (-) lays below the topmost portion () of the central bore () and above the lowermost portion () of the central bore ().
