Document Type and Number:
Japanese Patent JP3830977
Kind Code:
B2
Abstract:
A modular cutting tool assembly includes a tool holder (50) having at least one insert receiving pocket (52) and first (10,80) second cutting (100,102) inserts alternately receivable within the pocket (52). The first cutting (10,80) insert has a peripheral flank surface (18) configured to provide abutment features with mxn-fold rotational symmetry about the insert's central axis so that it can be restrained against the lateral support surfaces (56,58,60) in any of mnx angular positions, for at least one value of each of n and m where n>=3 and m>=2. The second cutting (100,102) insert has a peripheral flank surface (110) configured to provide reduced-symmetry abutment features with only n-fold rotational symmetry so that the second cutting insert can be restrained against the lateral support surfaces in only n angular positions. The peripheral flank surface (18,110) of at least the first cutting insert is configured such that a lower cross-section taken through the lower part of the first cutting insert perpendicular to the central axis has a recessed form.
