Patent ID: 7359763

Claim:
A cutting tool angle adjustment method comprising the steps of: (a) providing a transparent material and suspending a cutting tool above said transparent material, said cutting tool having a center axis, a transverse axis, and a cutting edge, said cutting tool having a predetermined specification; (b) lowering said cutting tool vertically to said transparent material to make an indentation on a top surface of said transparent material by the cutting edge of said cutting tool; (c) picking up the image of said indentation on the top surface of said transparent material; (d) digitalizing the image of said indentation into an image range of n*m pixels, and then figuring out a top edge proximity line and a bottom edge proximity line of the image of said indentation by means of a numerical analysis method; (e) calculating a top angle of deviation θ 1 between said top edge proximity line and a reference line, and a bottom angle of deviation θ 2 between said bottom edge proximity line and said reference line; and (f) calculating a angle of correction θ T of said transverse axis and a angle of correction θ A of said center axis subject to the formulas of: θ T =f 1 (θ 1 −θ 2 ), and θ A =f 2 (θ 1 +θ 2 ), in which f 1 and f 2 are correction parameters corresponding to the predetermined specification of said cutting tool.
