The elastic deformation of slicing blade, which is an important factor for elucidation of the outer-blade slicing mechanism, is discussed. This deformation is measured by using ' strain gauges, and analytical as well as experimental considerations are given for the effect of asymmetric wear of blade onto the deformation. Moreover, attritious wear of grain cutting edges on the blade side is observed. The results are obtained as follows. (1) The deformation extends over the contact area of blade with the workpiece. (2) The deformation is kept until the blade passes through the workpieces cut off, because the blade side is in contact with them. (3) The more asymmetric wear in the cross section of the blade brings the larger deformation, and makes the cutting accuracy lower. (4) The deformation causes the elastic contact between the side face of the blade and the work, which encourages the glazing wear of cutting edges.
