Although this compensation feature is most valuable in extreme taper cutting operations, it can be applied to any wire tool path involving independent U- or V-axis motions for improved accuracy. The cutting results are measured and the resulting data is plugged into a formula that then provides the TPCMP value for each cutting pass. The appropriate compensation values are based on a simple test cut that the customer must do using his or her material and cutting parameters. According to developers, taper cutting accuracy improves from 0.00122 inch to 0.0008 inch. The result is enhanced cutting accuracy and lower risk of wire breakage. This adjustment moves the wire slightly farther away from the surface at one end of the cut and slightly closer to the surface at the opposite end.

Essentially, this change in wire angle adjusts the position of the wire in relation to the workpiece surface so that cutting conditions are the same along the full length of the wire in the cut. Decades of collaboration have led to innovative solutions optimized for individual wire EDM brands and machines. It enables the programmer to apply a single numerical value that determines the appropriate change in wire angle at both the upper and lower positions of the wire guides. With over 30 years of commitment to the wire EDM community, ESPRIT is widely recognized as the market leader in CAM for wire EDM.

(Sudbury, Massachusetts).Ĭalled Volumetric Taper Compensation with four-axis overburn control or TPCMP (for toolpath compensation), this feature is available first on the FANUC RoboCut a-CiA series of wire machines equipped with FANUC series 31i-WB controls. A feature to compensate for this effect has been introduced on FANUC wire EDM models from Methods Machine Tools Inc. In addition to degrading geometric accuracy, this concentration of sparks may also cause the wire to break. Enjoying good transportation, we will offer you good after-sale services and fast delivery. The slower relative speed causes the energized wire to remove proportionately more material by producing an unwanted concentration of spark action in this portion of the workpiece. Taguti Industrial provides you with high quality agie charmilles for EDM, mitsubishi for EDM, sodick for EDM, fanuc for EDM, makino for EDM made in China which is of stable strength and advantages. This change in relative wire traverse speed creates conditions for an overburn where the part shape is tighter or narrower. One of the chief difficulties in these situations arises because the wire traverse speed relative to the workpiece surface becomes slower as the wire approaches the progressively tighter arc of the cone shape or the narrower width of the slope. Forum (HEIDENHAIN) - HEIDENHAIN develops and manufactures linear encoders, angle encoder, rotary encoders, and CNC controls for rigorous positioning tasks. Another example is cutting a slope in which the angle of the slope varies because one end of the slope is wider than the other. One example is a taper cut that follows a curve such as to produce a cone-shaped geometry.

Sodick used to provide a separate pc unit to program, with the same soft as the machine, and that worked fine, naturally.Īs wire cut programs don't have so many blocks, they are easy to copy on disks, but you must use the 720k format, instead of the normal 1.44mb. I can't tell you precisely what that is, but it is not an easy thing to solve with an ordinary pc. That generation of sodick machines had an specific issue with serial, wich had something to do with the bit transcription of the serial.
