ENHANCED - Moved MANDREL CYLINDER ENABLE option from OVERALL to BEND Rows and RENAMED

This change allows the mandrel to be switched ON or OFF individually for any bend row rather than for every bend row.

The option was MOVED and RENAMED to "MANDREL CYCLE ENABLE" because we cannot no longer anticipate that all mandrel actuators will be cylinders. For example, it is possible that we may use geared electric servo motors for the mandrel.

This new PER BEND feature is critical for mandrels in rectangular or square tubing that rotate 90 degrees, but the mandrel can only bend in one of the two planes.



This is the option list with the new title. Cylinder is changed to Cycle:



When loading older CNC Bender part files, the new Bend row mandrel option will always be set to OFF. To set the mandrel ON in every row, set the value to ON in one row, then press the "Copy Value to All Rows" button.

CHANGE - Added "RETURN" before "Angle" in "Early Mandrel Forward At Angle"

This option title change to "Early Mandrel Forward at Return Angle" removes an ambiguity on when this feature will take effect. The word "Return" indicates that it happens when the bend arm is RETURNING to setup for the next row.

CHANGE - To Mandrel Early Advance in Prebend Logic

Now the Mandrel Early Advance is activated only if the MANDREL CYLINDER ENABLE is ON in the first bend row.

ENHANCE - New Remark in Processlist For Mandrel Retract Override

To aid in diagnostics, the processlist builder now includes a special message in the PREBEND section when these mandrel cycle conditions exist:

• The MANDREL TYPE is anything other than NONE (In the Low Level)
• The HOLD MANDREL FORWARD setting is ENABLED in the last bend row

When these two conditions are true, then no automatic Mandrel Retract is issued in the PREBEND section of the processlist. To remind operators of this setup, this is the new remark in the processlist when these two conditions are true:

// ** MANDREL RETRACT OVERRIDE: "Hold Mandrel Forward" setting is ON in the last Bend. **

// ** MANDREL RETRACT OVERRIDE: The mandrel retract is NOT inserted. **
