G187 is an accuracy command that can set and control both the smoothness and max corner rounding value when cutting a part. The format for using G187 is G187 Pn Ennnn.

P - Controls the smoothness level, P1(rough), P2(medium), or P3(finish). Temporarily overrides Setting 191.
E - Sets the max corner rounding value. Temporarily overrides Setting 85.

Setting 191 sets the default smoothness to the user specified ROUGH, MEDIUM, or FINISH when G187 is not active. The Medium setting is the factory default setting.

note: Changing Setting 85 to a low value may make the machine operate as if it is in exact stop mode.
note: Changing setting 191 to FINISH will take longer to machine a part. Use this setting only when needed for the best finish.

G187 Pm Ennnn sets both the smoothness and max corner rounding value. G187 Pm sets the smoothness but leaves max corner rounding value at its current value. G187 Ennnn sets the max corner rounding but leaves smoothness at its current value. G187 by itself cancels the E value and sets smoothness to the default smoothness specified by Setting 191. G187 will be canceled whenever RESET is pressed, M30 or M02 is executed, the end of program is reached, or EMERGENCY STOP is pressed.
