Abstract
A method of driving screws into a workpiece using an automatic screw driving tool having first and second components, the first component including a screw bit. The method may include steps of measuring a relative displacement between the first and second components; driving, in a first phase, a first screw partially into the workpiece at a first speed until a target relative displacement value is reached; after the first phase, driving, in a second phase, the first screw further into the workpiece at a second speed that is different than the first speed; completing the driving process for the first screw; measuring a final relative displacement of the first and second components after the first phase to determine a final relative displacement value, and updating the target relative displacement value based on the final relative displacement value.
