CHANGES to CNC PROCESSLIST BUILDER

New Insert of ClampHomeComplete with PD Retract Timer

The Pressure Die Retract Timer COMDEF command can open the pressure die a small distance and simultaneously send the Clamp die home. The command is considered complete when the pressure die has arrived at its timed destination. The next step is often for a Post Bend Jog (which is a bend die clearance move for non split-die benders).

Because our operator station systems are becoming so fast, it is easily possible for the Feed axis to start the Post Bend Jog without the clamp die arriving completely home. This is a typical process list where this problem can occur:

[DISPLAY] Next Step: (FRB Row 2) Home Pressure Die For 200 MS And Clamp Home
PressureDieReturnWithTimer_SendClampAndBoostHome = tim2:200, cto:6000
[DISPLAY] Completed: (FRB Row 2) Home Pressure Die For 200 MS And Clamp Home

[DISPLAY] Next Step: (FRB Row 2) Home All Boost Dies
AllBoostReturn = cto:6000
[DISPLAY] Completed: (FRB Row 2) Home All Boost Dies

This is the new process list with the ClampHomeComplete command added to the logic:

[DISPLAY] Next Step: (FRB Row 2) Home Pressure Die For 200 MS And Clamp Home
PressureDieReturnWithTimer_SendClampAndBoostHome = tim2:200, cto:6000
[DISPLAY] Completed: (FRB Row 2) Home Pressure Die For 200 MS And Clamp Home

[DISPLAY] Next Step: (FRB Row 2) Open Clamp Fully
ClampHomeComplete = cto:6000
[DISPLAY] Completed: (FRB Row 2) Open Clamp Fully

[DISPLAY] Next Step: (FRB Row 2) Home All Boost Dies
AllBoostReturn = cto:6000
[DISPLAY] Completed: (FRB Row 2) Home All Boost Dies
