4.26 Milling Cycles

Overview of milling cycles

G791 Linear slot on the face. The position and length of the slot are
defined directly in the cycle; slot width = cutter diameter: Page 317
G792 Linear slot on the lateral surface. The position and length of
the slot are defined directly in the cycle; slot width = cutter
diameter: Page 318
G793 Contour and figure milling cycle on the face. The contour is
described directly after the cycle and concluded by G80
(compatibility cycle MANUALplus 4110): Page 319
G794 Contour and figure milling cycle on the lateral surface. The
contour is described directly after the cycle and concluded by G80
(compatibility cycle MANUALplus 4110): Page 321
G797 Face milling. Mills figures (circles, polygons, individual
surfaces, contours) as islands on the face: Page 324
G798 Helical slot milling. Mills a helical slot on the lateral surface,
slot width = cutter diameter: Page 326
G840 Contour milling. Mills ICP contours and figures. Closed
contours are machined inside/outside of the contour, or on the
contour. Open contours are machined from the left/right of the
contour, or on the contour. G840 is used on the face and lateral
surface: Page 327
G845 Pocket milling—roughing. Roughs out closed ICP contours
and figures on the face and lateral surface: Page 337
G846 Pocket milling—finishing. Finishes closed ICP contours and
figures on the face and lateral surface: Page 343
