Extracted text: 1. A workpiece with 25mm diameter is turned in a centre lathe with a back rake angle of 12 degrees and front relief angle 7 degrees. Calculate the actual cutting angles (rake angle and clearance angle) if the cutting tool is set (a) 0.8mm above the centre line of the work piece, and (b) 0.8mm below the centre line of the work piece.
