Stock removal for external contour (roughing) Contour turning Stock rem Enter the following values: Accept Pay attention to the yellow help text in the header The tool paths are only calculated once before stock removal and stored in a temporary subroutine. Only when one of the contours or a parameter in the cutting cycle has changed, are the paths recalculated. Page 14 Siemens AG 2002, All rights reserved, November 2002 Edition A. Grözinger

Removal of remaining stock Contour turning Cut resid mat Enter the following values: Accept Machining is now only performed at positions where residual material stock still has to be removed after the preceding stock removal operation.

Simulation Simulation Simulation is running Details The 3D view is not refreshed until you switch to another view. Cut << Back Simulation is based on block search with calculation to end of program. Simulation cannot therefore be performed simultaneously with machining on the machine! Simulation makes use of the tool operating data Simulation can also be performed with the function "program test" with dry run feedrate. You can control the velocity of the simulation with the override switch. Page 26 Siemens AG 2002, All rights reserved, November 2002 Edition A. Grözinger

To deactivate the zero offset enter the value 0. (Careful, the basic offset is always active!) << back If the first zero offset was not yet active, the axis positions in the workpiece coordination system (WCS) will now change. No compensatory movement of the machine axes is made! It is possible to manage up to 99 zero offsets. Page 28 Siemens AG 2002, All rights reserved, November 2002 Edition A. Grözinger

Probing a workpiece M Work Measure Enter the following values: Use the direction keys to traverse axes toward the required edge until the tool makes contact. Set zero offset The axis position of the Z axis in the workpiece coordinate system (WCS) now shows the value 5.0 mm. That corresponds exactly to the position of the tool tip with reference to the zero offset calculated (G54). A. Grözinger Siemens AG 2002, All rights reserved, November 2002 Edition Page 29
