Control system in brief TNC 151/TNC 155The HEIDENHAIN TNC 151flNC 155 is a 4-axis contouring control system. Axes X. Y and Z are linear axes: the fourth axis is provided for the attachment of an optional rotary table or use as an additional linear axis. The fourth axis can be connected or disconnected as required. The four-axis contouring control permits: l linear interpolation of any 3 axes. l circular interpolation of two linear axes: Complex contours can also be produced with the aid of parameter programming. The TNC 15VTNC 155 can be equipped with an optional 5 axis for spindle orientation. This feature allows accurate positioning of the spindle, when using the TS 51O/TS 511 infrared probing system. for example, or for certain tool change systems.

Programs may be entered either in HEIDENHAIN plain-language dialogue or . in standard IS0 6983 format.l

interactive

All interactive dialogue prompts, input values. machining programs and error messages are displayed on the control Screen. The program memory can accommodate up to 32 programs with a total of 3,100 blocks. The imachining piogram can be either keyed in or entered electronically via the data interface. In Transfer blockwise- mode. machining programs can be transferred from an external storage medium and run simultaneously. The TNC 151flNC 155 allows you to enter or edit a program while another program is running.

HEIDENHAIN provides the ME lOl/ME 102 magnetic tape unit and the FE 401 floppy disk unit for external storage of programs. The magnetic tape units use mini:cassettes for data storage; the floppy disk unit uses 3 112 diskettes. Each unit is equipped with two interfaces. making it possible to connect a peripheral device, such as a printer. in addition to the TNC.

Control

system

in brief

TNC 151/TNC 155Program test In Test run- mode. the TNC checks machining programs without moving the machine slides. Any errors in the program are displayed in the form of plan-language m~x+ages. Graphic program simulation provides another option for testing the program. Machining procedures can be simulated on the three main axes wtth a constant tool axis using a cylindrical end mill.

Upward compatibility

Programs created on the TNC 145 or TNC 150 can also be run on the TI\lC 151/TNC 155. The control system adapts the input later 10 the TNC 151lTNC 155. Thus an existing TNC 145,TNC 150 program library can also be used for the TNC 1511 TNC 155.

Changing buffer batteries

The buffer battery is the voltage swrce for the memow containlnq the machine warameters and for the control s&m program n&wry in case the external voltage supply IS switched off. It is located beneath the cover on the front panel of the control unit
