Abstract
Apparatus and method for skiving first and second work pieces using the same skiving tool to machine both work pieces. Flank cutting edges of the skiving tool subjected to a stronger load during machining of the first work piece are subjected to a lesser load during machining of the second work piece and vice versa. Accordingly, a substantially uniform load is subjected to both flank cutting edges overall, resulting in improved uniformity of wear to both flank cutting edges.
Claims12
A method for skiving a first work piece and a second work piece having rotationally-symmetric, periodic structures utilizing a skiving tool, the method comprising the following steps:
- moving a skiving tool into a first relative position in relation to a first work piece,
- executing a first skiving machining action of the first work piece, wherein one of (i) all right flanks and (ii) all left flanks of the periodic structure of the first work piece are finish machined, and the other of the all right flanks and the all left flanks are premachined,
- moving the skiving tool into a second relative position in relation to the first work piece,
- executing a second skiving machining action of the first work piece, wherein the flanks premachined during the first skiving machining action are finish machined,
- moving the skiving tool into a third relative position in relation to a second work piece,
- executing a third skiving machining action of the second work piece, wherein one of (i) all right flanks and (ii) all left flanks of the periodic structure of the second work piece that are opposite to the one of the all right flanks and all left flanks finish machined during the first skiving action, are finish machined, and the other of the all right flanks and all left flanks of the second work piece are premachined,
- moving the skiving tool into a fourth relative position in relation to the second work piece, and
- executing a fourth skiving machining action of the second work piece, wherein the flanks premachined during the third skiving machining action are finish machined.
A machine having a CNC controller, programmed and adapted to execute the following steps:
- moving a skiving tool into a first relative position in relation to a first work piece,
- executing a first skiving machining action of the first work piece, wherein one of (i) all right flanks and (ii) all left flanks of the periodic structure of the first work piece are finish machined, and the other of the all right flanks and the all left flanks are premachined,
- moving the skiving tool into a second relative position in relation to the first work piece,
- executing a second skiving machining action of the first work piece, wherein the flanks premachined during the first skiving machining action are finish machined,
- moving the skiving tool into a third relative position in relation to a second work piece,
- executing a third skiving machining action of the second work piece, wherein one of (i) all right flanks and (ii) all left flanks of the periodic structure of the second work piece that are opposite to the one of the all right flanks and all left flanks finish machined during the first skiving action, are finish machined, and the other of the all right flanks and all left flanks of the second work piece are premachined,
- moving the skiving tool into a fourth relative position in relation to the second work piece, and
- executing a fourth skiving machining action of the second work piece, wherein the flanks premachined during the third skiving machining action are finish machined.
