I'm working on a press feeder and I'm trying to figure out the calculations to determine what accel and decel rates I need.
I know the press runs at 20 strokes per minute. I know the Feed length is 12 inches and the feed angle is 60 degrees.
60sec/20 strokes= 3 seconds per stroke.
3sec/360 degrees= 0.008333 sec per degree * 60 degrees= 0.5 seconds
So now I know I have 0.5 seconds to feed 12 inches
I have a display which allows the operator to select the accel and decel percentages of the entire move. Meaning, if the operator selects 20% accel and 10% decel then the first 20% of the feed move is used to accelerate untill full speed. Travel at full speed for %70 and then decel for the last %10 of the feed.
I'm not sure how to calculate the acceleration/Deceleration and how to determine what the max speed will be.
Can anyone help me with the calculations?
