Abstract
The present invention relates to a rotary cutting tool consisting of a shank and at least one cutting section comprising a plurality of cutting teeth, the cutting section being conceptionaly and functionally divided into several sub-sections along the tool axis (“zones” for brevity), wherein each zone has its own core form and its own cutting edges, its own teeth land form and its own zone cutting length, these being selected according to the perceived task for which each zone of the tool is to be optimized.
Claims12
A rotary cutting tool comprising:
- a shank defined around a tool axis;
- and
- a cutting section comprising a plurality of teeth;
- said cutting section being divided into a plurality of different consecutive cutting zones defined along said tool axis of said shank and having predetermined axial extents;
- and
- wherein a first one of said plurality of different cutting zones comprises a first predetermined core form, a first predetermined zone cutting length, first predetermined cutting edges, and a first predetermined tooth land form such that said first one of said plurality of different cutting zones can perform a slotting operation;
- a second one of said plurality of different cutting zones comprises a second predetermined core form, a second predetermined zone cutting length, second predetermined cutting edges, and a second predetermined tooth land form such that said second one of said plurality of different cutting zones can perform a side milling roughing operation;
- a third one of said plurality of different cutting zones comprises a third predetermined core form, a third predetermined zone cutting length, third predetermined cutting edges, and a third pre-determined tooth land form such that said third one of said plurality of different cutting zones can perform a side milling finishing operation;
- a fourth one of said plurality of different cutting zones comprises grooves, forming said cutting teeth, blending into said shank, and wherein further at least one of said plurality of different consecutive cutting zones has a core section which has a diametrical extent that is constant throughout said axial extent of said at least one of said plurality of different consecutive cutting zones.

A rotary cutting tool comprising:
- a shank defined around a tool axis;
- and
- a cutting section comprising a plurality of teeth, said cutting section being divided into a plurality of different cutting zones extending consecutively along said tool axis and having predetermined axial extents, wherein each one of said different cutting zones has its own core form and its own cutting edges, its own teeth land form, and its own zone cutting length, said core form, said cutting edges, said teeth land forms, and said cutting lengths being selected according to a predetermined task for which each one of said different cutting zones of said rotary cutting tool is to perform a different predetermined operation;
- wherein in a first one of said plurality of cutting zones starting from an end face of said cutting tool, said cutting tool comprises structure for performing a slotting operation;
- in a second one of said plurality of cutting zones, said cutting tool comprises structure for performing a side milling roughing operation;
- in a third one of said plurality of cutting zones, said cutting tool comprises structure for performing a side milling finishing operation;
- and in a fourth one of said plurality of culling zones, said grooves forming said cutting teeth blend into said shank, and wherein further, at least one of said plurality of different consecutive cutting zones has a core section which has a diametrical extent that is constant throughout said axial extent of said at least one of said plurality of different consecutive cutting zones.
