Lesson 9 circular arc interpolation G02, G03 instructions

format: G02 x__ Z__ I__ K__ F or G02 x__ Z__ R__ F

G03 X__ Z__ I__ K__ F or G03 x__ Z__ R__ F

function: the circle fully implements the dynamic management of "in and out" arc interpolation g02/g03, which is distinguished in the processing plane according to the clockwise/counterclockwise rotation direction during interpolation. The determination of the processing plane depends on the direction of the observer, that is, the direction of the Y axis. Figure 1-13 shows the determination of the coordinate axis direction and arc interpolation direction of gjk6032 lathe

x, Z: the value is the coordinate value of the arc end point in the absolute command, and the distance between the arc end point and the starting point in the incremental command:

r: is the arc radius. When the center angle of the arc is O-1, in India.R is a positive value, and when the center angle of the arc is 180 ~ 3600, R is a negative value

i, K: refers to the coordinate increment of the circle center relative to the starting point in the X and l axis directions. Whether it is diameter programming or radius programming, l is the radius quantity; It can be omitted when l and K are zero. See figure,

note: l, K and R are equivalent in a program segment, and R is valid when I and K months are simultaneously instructed in a program segment
