Thread machining G32 dictates delay time dictates

Thread machining G32 of G instruction ＊ dictates related athletic way format: G32X__Z__R__E__P__F__ function: When executive G32 dictates, cutting tool can machine columnar whorl and the awl whorl that wait for pitch, end panel whorl. See a picture 1, 18 show a specification: X, Z: When G90, for terminus of thread machining contrail the coordinate of B is worth, contrail of opposite thread machining of B of terminus of thread machining contrail is when Gvalue="9" UnitName="l">9l only then the distance R that nods A, E: The ending of thread machining is measured namely the increment that C dot nods at B relatively (increment is when Gvalue="9" UnitName="l">9l/G90) . R states C dot photograph is nodded to B C dot expresses to be nodded at B relatively to increment short for the Yihe River in Z in X to radius increment. P: Fiducial pulse place is apart from main shaft the main shaft corner with whorl bit more initiative cutting. F: Bevel angle is in 450 the following. Bevel of lead of whorl of X axis direction is in 450 above, f notes for lead of whorl of X axis direction: Litre of enough fast feed should be installed in thread machining contrail paragraph δ and fall fast retreat a knife paragraph δ ' , in order to eliminate the pitch error that servo lag causes. F is whorl lead, when machining awl whorl, bevel angle α is in treatment of 450 the following screw cutting shape turning, its cutting amount is larger, general requirement mark second feed. Express the 1 one 4 feed frequencies that are cutting of commonly used whorl and quantity of penetration of a cutting tool. CNC Milling
