The program sorts this information into the necessary sequence and translates it into a language which can be readily understood by the SINUMERIK. This Programming Guide describes the programming possibilities for the SINUMERIK 880 and the standard range of functions of the system. The maximum values specified are limit values.

Program structure: Part program in input/output format Subroutines and cycles can be components of the program. Cycles are subroutines which have been created either by the machine manufacturer or by SIEMENS. They can be specially protected against misuse. The input sequence is arbitrary.

Page 47: Mirroring
In the case of turning machines the following will be mirrored with a transverse axis as a function of machine data: • Tool length offset • Position of tool cutting point When mirroring the Z axis this does not apply. 3–17 © Siemens AG 1991 All Rights Reserved 6ZB5 410-0HD02 SINUMERIK 880, (PG)
Page 48 In order to mirror the workpiece at the correct position, the zero must be offset by the value ”a”. This results in the distance of both workpieces from zero being the same. After mirroring, the zero can be reset to its original position. 3–18 © Siemens AG 1991 All Rights Reserved 6ZB5 410-0HD02 SINUMERIK 880, (PG)
Page 49 Program sections which must be mirrored take the form of self-contained subroutines in the program. The relevant mirroring function for the contour must then be selected before calling the subroutine. 3–19 © Siemens AG 1991 All Rights Reserved 6ZB5 410-0HD02 SINUMERIK 880, (PG)
Page 50 Special function @714 (clear buffer) makes it possible to stop any additional block increment calculation until the buffer is empty (please refer to Section 11). @714 or L999 must be used for all externally induced offsets, e.g. mirroring. 3–20 © Siemens AG 1991 All Rights Reserved 6ZB5 410-0HD02 SINUMERIK 880, (PG)
