Abstract
A method of clamping a first cutting insert or an adaptor to a holder. Either the holder includes two insert pockets configured for machining in two different orthogonal directions or the holder includes a single adaptor pocket configured for holding the adaptor in two different orthogonal directions. The method includes the steps of choosing one of two orthogonal directions for machining and securing either the first cutting insert to an appropriate one of the two pockets or securing the adaptor to the adaptor pocket for machining in the chosen orthogonal direction.
Claims19
A parting tool configured to selectively perform X-axis cutting in a forward direction (DF) and Y-axis cutting in an upward direction (DU) which is perpendicular to the forward direction (DF), the parting tool comprising:
- a tool holder (12) comprising:
- a holder head portion (32);
- a holder shank portion (34) configured to be secured to a machine interface (18);
- and
- an adaptor pocket (36, 400) formed in the holder head portion (32) and comprising:
- a first threaded tool hole (432);
- a first additional threaded tool hole (432′);
- a tool holder outlet aperture (434) for transferring coolant to the parting adaptor (14);
- an additional tool holder outlet aperture (434);
- and
- a pocket bisector plane (P1) about which the first threaded tool holes (432, 432′), and the outlet apertures, (434, 434′) have mirror symmetry.
- a parting adaptor (14) comprising:
- opposing first and second sides (19A, 19B);
- a peripheral edge connecting the first and second sides;
- and
- a plurality of insert pockets (15A, 15B, 15C, 15D);
- and
- an operative cutting insert (16) retained in one of said plurality of insert pockets, the operative cutting insert having a forwardmost cutting edge (30A);
- wherein:
- the parting adaptor (14) is configured to be selectively mounted to the adaptor pocket (36) of the tool holder (12):
- (a) in a first orthogonal position in which the first side (19A) of the parting adaptor faces the adaptor pocket (36) and the forwardmost cutting edge (30A) is oriented such that the parting tool is configured for X-axis cutting;
- and also
- (b) in a second orthogonal position in which the second side (19B) of the parting adaptor faces the adaptor pocket (36) and the forwardmost cutting edge (30A) is oriented such that the parting tool is configured for Y-axis cutting.
A parting tool configured to selectively perform X-axis cutting in a forward direction (DF) and Y-axis cutting in an upward direction (DU) which is perpendicular to the forward direction (DF), the parting tool comprising:
- a tool holder (12) comprising:
- a holder head portion (32);
- a holder shank portion (34) configured to be secured to a machine interface (18);
- and
- an adaptor pocket (36, 400) formed in the holder head portion (32) and comprising:
- a planar pocket surface (444);
- a first plurality of threaded holes (450A, 450C) formed on the pocket surface (444) and configured to secure a parting adaptor in a first orientation for X-axis cutting;
- and
- a second plurality of threaded holes (450A′, 450C′) formed on the pocket surface (444) and configured to secure said parting adaptor in a second orientation for Y-axis cutting;
- wherein:
- the first plurality of holes and the second plurality of holes are mirror symmetrically positioned about a bisector plane (P1).
A tool holder (12) comprising:
- a holder head portion (32);
- a holder shank portion (34) configured to be secured to a machine interface (18);
- and
- an adaptor pocket (36, 400) formed in the holder head portion (32) and comprising:
- a planar pocket surface (444);
- a first plurality of threaded holes (450A, 450C) formed on the pocket surface (444) and configured to secure a parting adaptor in a first orientation for X-axis cutting;
- and
- a second plurality of threaded holes (450A′, 450C′) formed on the pocket surface (444) and configured to secure said parting adaptor in a second orientation for Y-axis cutting;
- wherein:
- the first plurality of holes and the second plurality of holes are mirror symmetrically positioned about a bisector plane (P1).
