ASME B94.19:1997 pdf download MILLING CUTTERS AND END MILLS
1 SCOPE
This Standard covers high speed steel milling cuttersand end mills of one piece construction as listed inTables I through 62. It also includes general definitions,sizcs，and tolcrances.
2 NOMENCLATURE
2.1 Definitions
milling culter: a rotary cutting tool provided with oneor more cutting clements called teeth, which intermit-tently engagc the workpicce and remove material byrelative movement of the workpiece and cutter (secFig.1).
end mill: a milling cutter that is shank mounted tothe machine tool and has cutting teeth on the end inaddition to those on the periphery. It may be of singleor double end construction (see Fig.2).
2.2 General Classifications
2.2.1 Classification Based on Type of Reliefon Cutting Edgesprofile sharpened cufter: a cutter on which the reliefis obtained. and that is resharpened by grinding anarrow land back of the cutting edges. Profile sharpenedcutters may produce flat, curved, or irregular surfaces
form relieved cutfer: a cutter which is so relievedthat, by grinding only the faces of the teeth, the originalform is maintained throughout the life of the cutter.Form relieved cutters may produce fat, curved, orirrcgular surfaces.
22.2 Classification Based on Method ofMounting
arbor-type cufter: a cutter with a hold for mountingon an arbor and that usually has a keyway to receivea driving key.Sometimes called a shell-type cutter.
shank-fype curter: a cutter with a straight or taperedshank to fit the achine tool spindle or adapter.
2.3 Explanation of “Hand” of Milling Cutters
The terms right hand and left hand are used todescribe hand of rotation, hand of cutter, and hand offute helix.
2.3.1 Hand of Rotation (or Hand of Cut)right-hand rotation (or right-hand cur): the counterclockwise rotation of a cutter revolving so as to makea cut when viewed from a position in front of ahorizontal milling machine and facing the spindle,lefr-hand rotarion (or lef-hand cur): the clockwiserotation of a cutter revolving so as to make a cut whenviewed from a position in front of a hoizontal millingmachine and facing the spindle.
2.3.2 Hand of Cutter. Some types of cutters rcquire special consideration when referring to their handThese are principally cutters with unsymmetrical forms,face type cutters, or cutters with threaded holes
symmiefrical cuffer; may be reversed on the arhor inthe same axial position and rotated in the cuttingdirection without altering the contour produced on theworkpiece,and may be considered as either right orleft hand.
unsymmetrical cuffer: reverses the contour producedon the workpiece when reversed on the arbor in thesame axial position and rotated in the cutting direction.single angle rtilling cufter: when the larger diameterside faccs the vicwer. a single angle milling cutter isright hand if it must be rotated counterclockwise tomake a cut.When the larger diameter side faces theviewer, a single angle milling cutter is left hand if itmust be rotated clockwise to make a cut.
single corner rounding cufter: . when the smallerdiameter side faces the viewer, the cutter is right handif rotated counterclockwise to make a cut, and is lefthand if rotated clockwise to make a cut.
2.3.3 Hand of Flute Helix
sfraighr flule: a milling cutter with its cutting edgesin planes parallel to the cutter axis.
Milling cutters with fute helix in one direction onlyare described as having right- or left-hand helixes.
