Wire EDM Tab Cut Parameters

Patterns

• Standard Profile - creates the operation with a single pass along the Glue Stop portion of feature geometry.

 

Note: The Glue Stop portion of the feature is always placed at the end of the feature as defined by the Start Point of the feature.

 

• Flip Pass Direction

Select the check box to flip the cutting direction for the operation.

Clear the check box to use the standard direction for the operation.

 

• Use Knockout

Select this check box to apply a knockout distance when using a glue stop in the feature. The Knockout Distance becomes available to specify the length of the knockout tab that remains on the part. This is only available for Outside features or Open features set to Punch.

Clear this check box when not applying a knockout to a glue stop.

• Knockout Distance - determines the length of the knockout tab of the Glue Stop.

 

Important: The Knockout Distance must be less than the Stop Distance for the feature. If you type a value that is greater than or equal to the Stop Distance, the software automatically reduces this value to 50 percent of the Stop Distance.

 

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.
