Mechanics of Metal Cutting - Manufacturing Technology
Tool angles given in a definite pattern is called tool signature. The tool angles have been standardized by the American Standards Association (ASA).
TOOL SIGNATURE Tool angles given in a definite pattern is called tool signature. The tool angles have been standardized by the American Standards Association (ASA). As per ASA, the tool signature is given by the following order: (i) Back rake angle (ii) Side rake angle (iii) End relief angle (iv) Side relief angle (v) End cutting edge angle (vi) Side cutting edge, and (vii) Nose radius. There is no practice to put symbol for degrees and mm, simply starting the numerical value of each element. Example: A tool having 8, 8, 5, 5, 6, 6, and 1 as signature in ASA system will have the following angles. Back rake angle = 8° Side rake angle = 8° End relief angle = 5° Side relief angle = 5° End cutting edge angle = 6° Side cutting edge = 6° Nose radius = 1 mm.
