摘要：
Method for milling a threading of a screw or tapped hole, said threading having a cross section in the shape of a triangle with a truncated crest, comprising:
milling a first flank (V1) of at least one spire of said thread by means of a first comb (A) of a milling tool (F), wherein the teeth of said first comb (A) are spaced in relation to one another by a first pitch (P1);
milling a second flank (V2) of at least one other spire of said thread by means of a second comb (B) of said milling tool (F), wherein the teeth of the second comb (B) are spaced in relation to one another by a second pitch (P2) equal to the first pitch (P1) and offset from the teeth of the first comb (A) by a phase displacement (DP);
milling a truncated portion (V3) of said crest by means of a third comb (C) of said milling tool (F).
milling a first flank (V1) of at least one spire of said thread by means of a first comb (A) of a milling tool (F), wherein the teeth of said first comb (A) are spaced in relation to one another by a first pitch (P1);
milling a second flank (V2) of at least one other spire of said thread by means of a second comb (B) of said milling tool (F), wherein the teeth of the second comb (B) are spaced in relation to one another by a second pitch (P2) equal to the first pitch (P1) and offset from the teeth of the first comb (A) by a phase displacement (DP);
milling a truncated portion (V3) of said crest by means of a third comb (C) of said milling tool (F).
