CNC Bender v10-20080226
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:
PressureDieReturnWithTimer_SendClampAndBoostHome = tim2:200, cto:6000 AllBoostReturn = cto:6000 FeedPositive = pos0:50.80000000, vel0:900.00000000, ump0:1, cto:60000
The PressureDieReturnWithTimer_SendClampAndBoostHome command sends the pressure due out a timed duration then issues a constant energized clamp and PD boost outputs to home. In this case, the process is so fast that the FeedPositive command may be start moving before the clamp die returns home. (This is more likely to happen when the boost is already home because PD Boost is switched off.)
This is an example of the new process list with the ClampHomeComplete command added to the logic:
PressureDieReturnWithTimer_SendClampAndBoostHome = tim2:200, cto:6000 ClampHomeComplete = cto:6000 AllBoostReturn = cto:6000 FeedPositive = pos0:50.80000000, vel0:900.00000000, ump0:1, cto:60000
