If bit 7 (CHPX) of parameter No. 8360 is set to 1, the chopping feedrate
cannot be set by using the chopping screen.
The chopping screen can be used to set chopping data regardless of the
current mode, even during automatic or manual operation that includes
chopping. If the level of memory protection signal KEY2 (G046#4) is
currently low, however, chopping data cannot be set.
To enable measurement of the tool length, the following functions are
supported: automatic measurement of the tool length by using a program
command (G37) (automatic tool length measurement, described in
Section II.14.2) and measurement of the tool length by manually moving
the tool until it touches a reference position, such as the workpiece top
surface (tool length measurement, described in Subsection III.11.4.2). In
addition to these functions, tool length/workpiece origin measurement B
is supported to simplify the tool length measurement procedure, thus
facilitating and reducing the time required for machining setup. This
function also facilitates the measurement of the workpiece origin offsets.
This function allows the operator to specify T/M code commands or
reference position return, by means of a manual numeric command, while
the tool length offset measurement screen is displayed.
Procedure for measuring the tool length offset value
The tool length offset value can be measured by manually moving the tool
until it touches the workpiece or a reference block. For details of this
operation, refer to the manual supplied by the machine tool builder.
1 Move the tool to the tool change position by means of manual
reference position return, for example.
2 Press mode selection switch HANDLE or JOG.
3 Set the tool offset value measurement mode switch on the machine
operator’s panel to ON. The tool length offset measurement screen,
shown below, appears and ”OFST” blinks in the status display at the
bottom of the screen.
The tool length offset measurement screen varies slightly depending
on whether tool length offset memory A, B (geometry compensation
and wear compensation are treated differently), or C (geometry
compensation and wear compensation are treated differently, and
cutter compensation and tool length compensation are treated
differently) is used.
