Single point Cutting tool signature

1 Answer

Answer :

The shape of a tool is specified in a special sequence and this special sequence is

called tool signature. The tool signature is given below

(i) Back rake angle

(ii) Side rake angle

(iii) Clearance or End Relief angle

(iv) Side Relief angle

(v) End cutting edge angle

(vi) Side cutting edge angle

(vii) Nose radius


A typical tool signature of single point cutting tool is 0-7-6-8-15-16-0.8. Here this tool signature indicates that the tool has 0, 7, 6, 8, 15, 16 degree back rake, side rake, end relief, side relief, end cutting edge, side cutting edge angle and 0.8 mm nose radius.
