Abstract
A device and method for measuring and adjusting an electrode used during electrical discharge taper machining, referenced on three axes, Y and Y horizontal and Z vertical, whereas two linear geometric references, bottom and top, which may be intersected by a wire, each of them lying in a plane XY, the references being offset from one another in a direction XY by a sufficient distance to make it possible to insert a vertical electrode between the two without either of them being intersected by the wire, a base element serving as a support to the references and as an attachment stay on the work bed of the machine.
Claims11
Device for measuring and adjusting a wire electrode used during electrical discharge taper machining, referenced on three axes, X and Y horizontal and Z vert comprising the following elements:
- two geometric references, bottom (7) and top (8), which may be intersected by a wire, each of them lying in a plane XY, the said references being offset from one another in a direction XY by a sufficient distance to make it possible to insert a vertical electrode between the two without either of them being intersected by the wire, a base element serving as a support to the said references and as an attachment stay on the work bed of the machine.
Device for measuring and adjusting a wire electrode used during taper machining processes on an electrical discharge machine comprising:
- means for moving axes of the machine and for measuring their positions,
- means for detecting an interference between the wire electrode and top and bottom geometric references (7, 8),
- a bottom wire-guide (2) movable in a plane of coordinates XY,
- a top wire-guide (4) movable in a plane of coordinates UV parallel to XY, and movable in a vertical direction Z perpendicular to the planes XY and UV,
- further including
- a plane P defined by the axis of the wire set close to the vertical and by an inclination vector {right arrow over (ΔUV)} in a plane UV, and
- top and bottom geometric reference (7, 8), each lying in a plane XY with two different heights (z1, z2) intersected by the wire successively and separately during a movement (V) in the plane P, this movement capable of being made separately by one or simultaneously by the bottom and the top wire-guides.
