Wire EDM parameter problem

[chatmak 0]

Hello,

dealing with wire EDM machine programming where it performed with Creo 3.0. In HELP Creo 3.0 writes that processing of 2D contours is possible to introduce a tilt angle of the thread using the parameter taper_angle, but me this parameter it does with the table of parameters. My question is any of you know what can be the reason for it not?

 

Thanks in advance.

 

Best regards

You are referring to: 

 

Register Tables
You can specify generator, cutcom, technology, offset, and flush registers, as well as taper and feed values, for Wire EDM NC sequences by using a register table. This allows you to set different register, taper, and feed values for each cut motion type (Approach, No Core, Rough, up to 16 Finish motions, and Detach). Register tables can be created either at setup time, or at the time of defining the NC sequence.Note:  Cutcom and Taper registers are not supported for No Core motions.

If a register table is specified for an NC sequence (either by setting the REGISTER_TABLE parameter or using the Select command on the CR/SEL RGR menu), then register values for each cut motion specified in the register table will be output to the CL data file. These values take precedence over the register values and feeds specified in the NC sequence parameters file.

 

 

To Specify Taper Angle for 2-Axis Contouring
The Taper Angle option on the INT CUT menu, available for 2-Axis Contouring Wire EDM only, allows you to select pairs of points on the tool path: the first point is where the taper angle is turned on, and the second—where it is turned off.
1. On the INT CUT menu, click Taper Angle.
2. The TAPER ANGLE menu opens with the options:
◦ Add—Add pairs of taper points.
◦ Remove—Delete a previously defined pair of taper points by selecting one of the
points.
◦ Show—Display the currently defined pairs of taper points.
◦ Redefine—Modify location of taper points or the taper angle value.
3. Click Add.
4. Select an option from the NOW/NEXT menu to specify when the tool axis position is to
be changed:
◦ Now—At the selected point.
◦ Next—At the next GOTO point.
5. Select a point on the cut motion to specify where the taper angle is to be turned on.
6. Select the appropriate option from the NOW/NEXT menu, if needed, and select another
point on the cut motion to specify where the taper angle is to be turned off.
7. Click Enter and enter a value for the taper angle for this pair of points. Previously
specified values, if any, will be available for selection.

Thanks to many of the answers, but these opportunities for the them know. Just interested me taper_angle parameter because HELP wrote it, but not available for use or at least I do not know how to turn it on. In Parameters IM but it is not displayed during the creation of instrumental transition does not appear. Thank you once.

I understand this parameter is related to the machine, and not to transition.

Уважаемые коллеги,

помогите, пожалуйста, понять появление такого

участка в траектории реза проволокой (Creo 3.0)

Уважаемые коллеги,

Это автоматическая синхронизация контуров.

Что бы убрать, можно изменить параметр AUTOSYNCH_START_END на НЕТ

или создать принудительную точку синхронизации в этом угле.

 

P.s. Обычно для реальной работы считают не эквидистанту, как в Вашем примере, а непосредственно контур.

Диаметр проволоки, межискровой зазор и пр. обычно учитывается технологическими параметрами конкретного станка.
