7 Actions Executed in Manual Operation Modes
7.1 Single Block Operation
A single block can be entered by selecting BLOCK INPUT screen of the PROGRAM screen
menu and pressing the action menu key. This action can be used only in jog, incremental jog
and manual handle modes. The data input is discussed in the chapter
3.3.4 “SINGLE
BLOCK Screen” on the page 34 .
Only a program block not referring to previous or following blocks can be entered, i.e., for
example a block containing tool nose radius compensation
cannot be entered. There are no
further restrictions, e.g. canned cycles, subprograms or macros can be started by means of
single block operation.
After terminating single block input caption SBEX appears in the 2
nd
field of status bar. With
the START button in effect the single block is executed.
7.2 Work Zero Point Offset and Tool Length Offset Measurement
In the course of measuring work offsets and tool length offsets by touching the workpiece
surface, of which the sizes are known, manual moving of axes is needed. It follows, that it is
practical to use manual operation modes in case of both activities. If, when measuring, switch-
over of spindle revolution or a new tool is needed, it can be executed by means of single block
input without changing operation modes.
L Warning!
Work offset and tool length offset measurement can be executed only after reference
point return.
