5 NC-Cycles Introduction Introduction 1.1 Availability of NC Cycles By means of the carefully directed transmission of data to an NC subroutine with the use of NC variables, it becomes possible to parametrize this subroutine which is then designated an NC cycle. The user can program NC cycles himself. Programming within NC program no. 99 guarantees general availability within an NC program package. Installing and programming under menu item cycle revision guarantees general availability all within one process. Generally, the standard INDRAMAT cycles should be installed there and allocated to the processors (see Description of Parameters - Cycle Handling ). Standard cycles Optional NC cycles This manual describes all available Indramat cycles. They are, however, not always part of the standard installation. The Indramat drilling cycles (see Chapter 2) are part of the standard installation. The NC cycles of the following chapters are only available on additional installation disks. For the content of these disks, please refer to the corresponding list in attachment 1. Indruction: As variables are already being used in the INDRAMAT cycles, these are available for further NC programming purposes only on a limited basis. In addition, branch marks cannot be assigned to NC cycles more than once. Doing so would generate the following message, if the NC program package or the parameter block are transmitted to the control unit memory: ÄEUDQFKPDUNWZLFHGHILQHG³ The first symbol for the branch mark in the cycles supplied by INDRAMAT is always (e.g.,. LABEL). For this reason, a user program should n o t use the branch mark as its first symbol. Some of the INDRAMAT cycles cannot be processed at all levels. Please note the sample programs and the procedures described. ATTENTION In the event of an error message, NC cycles are brought to a halt with the NC command HLT, or Q function. Please note the messages on the diagnostic display and the text notes concerning the NC cycles. A renewed start command using ADVANCE can cause the tool to brake and mechanical damage to the machine. INDRAMAT cycles always work in the base programming unit defined in the process parameters. They cannot be switched with G70/G71!

The subsequent feed proceeds with Feedrate infeed (@177) to the depth of the cut (@173). The tool then moves linearly with Feedrate plane (@176) and length (@171), in terms of the angle (@175), as relates to the positive first main axis.

The final milling procedure is less than the full Chip depth, if the stretch of safety distance to depth is not equal to a multiple integer of the Chip depth.
