Carriage Knee Calibration is critical for accurate knee positioning. The knee calibration procedure verifies that knees are a set distance from the saw line. Knee position is monitored by the probe inserted into the knee cylinder.
Step by Step Knee Calibration Procedure
Cut down a cant to a easy to measure size, IE 10x10
Navigate to the knee calibration page on the PLC HMI
For Each Knee on the carriage
Ensure knees are set at the expected dimension and cut a line
Measure the actual dimension of the cut piece between the knee plate and the sawline
Input the actual measured dimension if different from the expected dimension.
Repeat all steps until set dimension matches measured dimension for each knee.
*If significant Knee Calibration changes occur, Scanhead Calibration is recommend.
Slab sizes are smaller/larger than expected
opening faces differ from expected face drawn by optimizer PC (also see scanhead calibration)
Final cant dimensions are incorrect, or final cants are tapered
Major mechanical parts/components are changed on one or more carriage knees
