5 Programming Tool Movements 5.5 Path Contours - Polar Coordinates Circular path G12/G13/G15 around pole I, J, K 5-30 The polar coordinate radius is also the radius of the arc. It is already defined by the distance from the POLE to the starting point S . Input • Polar coordinate angle H for arc end point • You can enter values from –5400° to +5400° for H. Defining the direction of rotation You can program the following directions of rotation: • Clockwise direction of rotation G12 • Counterclockwise direction of rotation G13 • No direction of rotation defined The tool moves in the direction of rotation defined in an earlier block. G15 H G 1 3 0 If necessary, enter also: 2 Radius compensation R Feed rate F Miscellaneous function M END Resulting NC block: G12 H30 * J Y I R H Fig. 5.36: Circular path around a pole Program the circle with polar coordinates and clockwise rotation. Enter the angle of the arc end point, for example H = 30°. Terminate the block. E G13 S X TNC 360
