The decimal will be in position 18. All open posi

40、tions will be zero.If position 4 is a Q, R, S, T, U, V, W, Y, Z, 1, 2, 3, the shank will be expressed in millimeters. The decimalpoint will be in position 19. All open positions will be zero.If you use a standard shank diameter, you will be able to get OAL by adding the standard LOC and standardleng

41、th of the shank together. This can be found by looking at tables listed in publications in 2.1.1 and 2.1.43.3.12 POSITION 22, 23, 24, 25, 26, AND 27RADIUS, CORNER CHAMFER, POINT, TAPERThis position would beused to define a radius, corner chamfer, point, or taper. If position 16 indicates a 1, 2, 3,

42、4, the tool is a square end without any end teeth modification.If position 16 indicates a 6, 7, 8, 9, the tool has a corner radius. This is probably a modification to a standardtool. The radius will be expressed in inches or millimeters depending upon the how the cutter is dimensioned.If the measure

43、ment is in inches, it will be expressed to the nearest one ten thousandth of an inch. Position23 will be a decimal point.If the measurement is in millimeters, it will be expressed to the nearest one thousandth of a millimeter.Position 24 will be a decimal point.EXAMPLE0.1875 - - .1875 Corner Radius1

44、2.000 - - 12.0 mm Corner RadiusIf position 16 indicates A, B, C, D, the tool has a corner chamfer. This is probably a modification to astandard tool. The corner chamfer will be expressed in inches or millimeters depending upon how the cutteris dimensioned. NOTEThe length of the chamfer will be measu

45、red in a plane parallel to the axis of the tool and the anglewill referenced off the axis as well.If the measurement is in inches it will be expressed to the nearest one thousandth of an inch. The angle willbe rounded off to the nearest half angle. The maximum chamfer length will be 0.999 in. The de

46、cimal pointwill be implied to be in the front of position 22.SAE J2342 Issued JAN1999-8-If the measurement is in millimeters, it will be expressed to the nearest one tenth of a millimeter. The anglewill be rounded off to the nearest half angle. The maximum chamfer length will be 25.4 mm. The decimal

47、point will be implied to be in the front of position 24.EXAMPLEPlease note that both the chamfer length and the chamfer angle are contained in positions 22through 27.EXAMPLE0. 438450 - - 7/16 in (.4375) x 45 degrees12.7555 - - 12.7 mm x 55.5 dgreesIf position 16 indicates a P, the tool has a point.

48、The Point Angle will be expressed as an included angle, witha decimal point in position 26. The angle will be expressed to the nearest one half of a degree with position22 a zero.EXAMPLE0118.0 - - 118 degrees included point angle0.135.5 - - 135.5 degrees included point angleIf position 3 is a C, the taper (per side) will be expressed to the nearest one half of a degree. Position 26 willbe a decimal point with position 22 and 23 a zero.EXAMPLE 0028.0 - - 28 degrees per side0027.5 - - 27.5 degrees per sideNote if position 3 is C, and position 16 = 5, the tool will hav
