Explanation of EIA Program 3B

N1 Tool change #1

N2 Selects left cutter compensation, activates tool #1's "D" offset, and turns on spindle CW

(3000 rpm)

N11, The center of the second arc

N3 Sets a "point before pierce" of X0 Y99

Note: Machine does not move to this position.

N4 Sets a "pierce point" of X0 Y0; moves to its compensated point as established by the

previous block

N5 Calls tool #1's "H" offset, positions Z to .1, and turns on coolant

N6 Feeds Z-.375 at 5 ipm

N7 Line move to X1 Y0 at 25 ipm

N8, Center of the first arc

N10 Radius of the first arc

N12

N13 Radius of the second arc

N14 Tangent line function

N15 First arc with calculated end points

N16 Line tangent to both arcs

N17 CW arc 1" radius using an XC7 YC2 and an end point of X5 Y2

N18 CCW arc 2" radius using an XC7 YC2 and an end point of X9 Y2

N19 Line move to X9 Y5

N20 Line move to X0 Y5
