Abstract
When wire electrode discharge is used for machining cutting tips, one cutting tip rotates around a workpiece axis in a program control mode each time, the cutting tip at least is aligned to one of three axes of a Cartesian coordinate system relatively to the wire electrode, and one axis of the coordinate system is in parallel with the workpiece axis. When rear surfaces which are adjacent to a cutting edge are machined, the cutting tip rotates around the workpiece axis, the contact point between the wire electrode and the cutting edge is on the cutter axis in any case, a cutter axis and two axes (X, Y) of the wire electrode and the coordinate system extend orthogonally. When rear parts which are adjacent to sections whose cutting edges are not in parallel with the workpiece axis are machined, the wire electrode rotates around the cutter axis.
Description
The present invention relates to utilize the method for wire electrode discharge processing cutting tip, and the electrical discharge machine that relates to cutting tip.
For make or again sharpening purpose and to process cutting tip be in the many purposes of the present invention one.For example cutting tip is fixed on milling cutter or the rotation knife bar (turning tool holder) with the method for soldering or clamping; Cutting tip can be designed to calibration and insert, thereby has a plurality of cutting edges, and this just can successively enter the operating position.Particularly be equipped with the cutting tip of complex contour usually in order to the milling cutter of converted timber or plastic board, plate or bar, according to known method with known machine processing cutting tip the time, in control and programming, need sizable cost could on back adjacent and front, guarantee best relief angle and anterior angle respectively with each cutting edge of this cutting tip.Consider required so far a large amount of programing works, often will on the value of these angles, do to take all factors into consideration that this understands on the cutting ability of cutting tip and working life adverse influence.
For this reason, an object of the present invention is to improve the discharge-treating method and the electrical discharge machine of cutting tip, even if also can under reduction programming and regulate expenditure, critically obtain best angle, particularly relief angle under the condition of cutting edge shape complexity.
According to the present invention, with regard to method, this problem is to solve like this on the basis of above-mentioned the sort of method, make a cutting tip with the axis rotation of stored program control system around workpiece at every turn, and, in this coordinate system, there is an axis to be parallel to the axis of this workpiece with respect to this wire electrode at least one axis linear alignment among Di Kale coordinate system three axis.During the processing back adjacent with a cutting edge, cutting tip around the axis of workpiece rotation so that contacted this of wire electrode and cutting edge put all is in all cases on the tool axis that two axis with wire electrode and coordinate system all stretch orthogonally.
In this case, particularly advantageous is that if during the each several part of the processing back adjacent with each section of the cutting edge that is not parallel to axis of workpiece, wire electrode is around the tool axis rotation.
Around this tool axis do rotatablely move can in addition at cutting edge when in a plane, measuring under the situation about stretching on the different radial distances of this axis of workpiece perpendicular to axis of workpiece, the relief angle of cutting tip also remains unchanged.With tool axis be configured to axis of workpiece meet at right angles and workpiece spindle extend by cutting edge, on horizontal back, also obtained distortionless processing, its relief angle is to measure in being parallel to a plane of axis of workpiece.
In view of this goal of the invention relates to lathe, and according to the present invention, this problem is to solve on the basis of above-mentioned the sort of lathe, and the electrical discharge machine of this cutting tip comprises:
A clamping device clamps at least one cutting tip,
A programmed control electric machine is used so that this paring blade centers on the axis rotation of workpiece,
A wire electrode clamping device, a wire electrode is just worn on this clamping device, and
The skate apparatus that has the program control driving device is done linear relative motion in order to three axis along cartesian coordinate system between cutting tip and wire electrode.
Wherein the wire electrode clamping device is pressed stored program control system around the rotation of tool axis, thereby above-mentioned tool axis and wire electrode and extend with two axis of this coordinate system with meeting at right angles.
The simple modification of lathe of the present invention is: the wire electrode clamping device is installed on the spinner member, can also carry one and measure the trace head, in order to profile and the surface of measuring this cutting tip around this tool axis rotation.
Explain one embodiment of the present of invention with reference to the accompanying drawings in detail.
