5 Programming Tool Movements 5.4 Path Contours – Cartesian Coordinates 5-24 To program a circular path CT with tangential connection: CT e.g. X 5 0 Example for exercise: Circular arc connecting to a straight line Coordinates of the transition point from the line to the arc: X = 10 mm Y = 40 mm Coordinates of the arc end point: X = 50 mm Y = 50 mm Milling depth: Z = –15 mm Tool radius: R = 20 mm Part program COORDINATES? Y + / 1 0 ENT If necessary, enter also: • Radius compensation • Feed rate • Miscellaneous function Resulting NC block: CT IX+50 IY-10 RR Enter the coordinates of the arc end point, for example IX = 50 mm, IY = –10 mm.

5 Programming Tool Movements 5.4 Path Contours – Cartesian Coordinates Corner rounding RND TNC 360 The tool moves in an arc that connects tangentially both with the preceding and the subsequent elements. The RND function is useful for: • Rounding corners • Approaching and departing contours on a tangent Input • Radius of the arc • Feed rate for RND Prerequisite On inside corners, the rounding arc must be large enough to accommodate the tool. 1 2 G1 G2 Fig. 5.33: Rounding radius R between G1 and G2 R R S R Fig. 5.34: Smooth approach with RND • In the preceding and subsequent blocks both coordinates should lie in the plane of the arc. • The corner point E is cut off by the rounding arc and is not part of the contour. • A feed rate programmed in the RND block is effective only in that block. After the RND block the previous feed rate becomes effective again. E 5-25
