5 Programming Tool Movements 5.5 Path Contours - Polar Coordinates 5-28 Polar coordinates are useful for programming: • Positions on circular arcs • Positions from workpiece drawings showing angular dimensions Section 1.2 "Fundamentals of NC" (see page 1-8) provides a detailed description of polar coordinates. Polar coordinate origin: Pole I, J, K You can define the pole anywhere in the program before the blocks containing polar coordinates. Enter the pole in Cartesian coordinates as a circle center in a I, J, K block. A pole definition remains effective until a new pole is defined. The designation of the pole is derived from its position in the working plane. Working plane XY YZ ZX H G 1 0 R 5 3 0 POLE I, J J, K K, I You can define the last programmed position as POLE by entering G29. Straight line at rapid traverse G10 Straight line with feed rate G11 F ... • You can enter any value from –360° to +360° for H. • Enter the algebraic sign for H relative to the angle reference axis: For an angle from the reference axis counterclockwise to R: H>0 For an angle from the reference axis clockwise to R: H
