Wire EDM 2 Axis Rough Cut Parameters

Patterns

• Standard Profile - creates the operation with a single pass along the feature geometry.
• Coreless - creates a rough cut operation to pocket all material inside of the feature geometry. This is used to eliminate any core (or slug) that results when using the Standard Profile. The Start Hole size and location are handled in the Leads page of the operation in the Wire EDM Wizard.
• Stepover % - controls the stepover or distance between each pass of the coreless operation as a percentage of the wire diameter for the job. This option only displays when Coreless is selected.

 

Note: The Coreless pattern is only available for the Rough Cut operation of a 2 Axis Inside feature when both No Taper and No Glue Stop are selected in the Feature settings.

Compensation

The compensation commands determine whether or not the wirepath output is offset from the selected geometry in order to properly cut the feature. The software can output the wirepath offset to the left, right, or center line (compensation off). When System Compensation is turned off, the software outputs the wirepath on center line with the offset being handled by the output of the proper Machine Compensation codes.

 

System Compensation

• On - forces the software to automatically output the wirepath with the proper compensation (left or right) based on the feature type and cut direction. This setting is available for all Inside or Outside feature operations.

 

Note: When creating a 2 Axis Open or 4 Axis Open Wire EDM feature, the System Compensation options change from On and Off to Left, Right, and Off as described next.

 

• Left - forces the software to offset the wirepath to the left of the feature geometry based on the chain direction defined for Open feature operations.

• Right - forces the software to offset the wirepath to the right of the feature geometry based on the chain direction defined for Open feature operations.

• Off - turns System Compensation off for the operation. The software outputs the wirepath on center line and Machine Compensation should be used.

 

Machine Compensation

• On - forces the software to automatically output the proper Machine Compensation (G41 or G42) based on the feature type and cut direction. This setting is available for all Inside and Outside feature operations.

 

Note: When creating a 2 Axis Open or 4 Axis Open Wire EDM feature, the Machine Compensation options change from On or Off to Comp Left/G41, Comp Right/G42, or Off as described next.

 

• Comp Left/G41 - forces the software to offset the wirepath to the left of the feature geometry based on the chain direction defined for Open feature operations.

• Comp Right/G42 - forces the software to offset the wirepath to the right of the feature geometry based on the chain direction defined for Open feature operations.

• Off - turns off the output of Machine Compensation codes. The wirepath is output on center line unless System Compensation is used.

Taper Settings

The following parameter is an informational display that shows when taper is applied to the feature. When No Taper is selected in the Feature settings, this doesn't display.

 

• Apply Taper

Displays when taper is applied to the feature. This is an informational display that can't be edited.

Stop Settings

• Apply Stop Points

Select the check box to apply the selected Stop Point geometry to the operation. This outputs a stop code in the program when the wire reaches the assigned Stop Point location on the profile.

Clear the check box to not apply the selected stop point geometry to the operation.
