With the large radius guide of the "taper cutting expert system", the wire is not affected by any local force when it is bent on the curved section of the guide, so the wire is in a stable state.
When a normal or straight wall guide is used, the small arc radius of the guide forces the wire to bend sharply, which causes the wire to vibrate.
When the wire between the two guides flexes, machining a simple workpiece can also cause defects. In order to compare the machining results, the roundness measurement was carried out on three different parts of the workpiece. The measurement was performed using a high-precision instrument Talyrond, which can be used to determine the deviation between the actual machined circle and an ideal circle.
A significant and very important concept when angle changes occur in the same face machining is that the attachment point of the wire in the guide changes as the machining angle changes.
Why does the workpiece fixed on the table cause ΔZ? When the attachment point changes, the reference Z moves with it, which causes the position of the programmed reference plane to change even if the workpiece does not actually move.
Charmilles' taper cutting expert system To solve all problems, Charmilles developed the TAPER-EXPERT taper cutting expert system.
TAPER-EXPERT comprehensively solves the problem of high precision taper machining and good surface roughness. First, the problem of "selecting the wire and its guide for a given machining angle" can be fully solved with the option of Charmilles. Secondly, the software modification measures introduced by Xia Mier data ensure that the geometric contour of the workpiece has strict precision requirements.
TAPER-EXPERT includes:
* Selection of electrode wire;
* guidance system;
* Electrode wire loop stability;
* Software correction of the datum plane.
The following three examples show that the taper cutting expert system can be used in a variety of applications, including the following two aspects:
* the flatness of the parting line in the tensile die;
* Geometric accuracy of the mold without the straight cylindrical portion on the reference plane.
Two identical machining comparisons were made for this workpiece, one using TAPER-EXPERT and the other not. In addition to the surface quality, significant differences can be found on the parting line. If the datum correction is not performed, the bond line between the taper and the cylinder is not straight.

Wrench: A commonly used installation and disassembly tool.Wrench is a hand tool that uses the principle of a lever to turn the opening or socket of bolts, screws, nuts, and other threaded tightening bolts or nuts.
Wrenches are usually made of carbon or alloy structural steel.
The wrench is usually provided with an opening or sleeve hole for holding the bolt or nut at one end or both ends of the handle. When it is used, external force is applied to the handle along the direction of thread rotation to twist the bolt or nut.
