In this paper the fundamental investigations are performed to measure the stresses at the cutting edge and to analyze the occurring mechanism of initial damage. Under the simplified two dimensional cutting condition, the object of study is wedge shaped plane with uniformly distributing oblique load which is imagiined 60 degrees of the tool angle for an example. Specimens are made of acrylate resin plate of about 3mm thickness. The Caustics patterns formed by reflected lights from the both surfaces of plate are observed and those characteristics with loading conditions are investigated in detail. On the other hand the computational theoretical patterns by the formulae based on mapping method are plotted. It is clarified that these two patterns are coincided accurately enough.
