3. BASIC OPERATIONS
• Explanation of each operation mode is as mentioned below.
No. Item Description
0 Power OFF The main power is turned off.
3 Count mode
Counter basic mode in which machining operation is
performed.
4 Display OFF mode
Entered from the count mode with the [ON/OFF] key.
Counting is still performed.
5 Parameter mode Parameters are input in this mode.
6 Origin recall Recalls the scale origin.
7 Origin storage Stores the scale origin.
8 Zero approach mode
By inputting a desired size, zero approach
machining that is to perform machining to approach
the display value to zero is performed.
The zero
approach buzzer is available.
9 Tool number switching Switches to the number of the tool to be used.
10 Tool offsetting A compensation value for a tool length is set in this mode.
IMPORTANT
Before proceeding to the machining in 3: Count mode, it is necessary to perform 10:
Tool offsetting.
3.3.3 Configuration of coordinates
Coordinates of the KA counter have the following configuration:
1 2 3 4
ABS
INC
3.3.4 Setup for tool offset
The KA counter is provided with the function for compensating the difference in each tool
length and displaying always the center of a workpiece (ABS coordinate) or the depth of
cut (INC coordinate) with respect to the tool tip. To use this function, the counter needs to
store the lengths of each tool to be used. The setting up of these lengths in the counter is
called tool-offset setup. The tool offset is set in the too offset setup mode.
This section explains the procedure for setting tool offset values.
The following figure shows a state in which some tools are set on a lathe.
Four tools are attached to the tool post and each tool is assigned a tool number as shown
in the figure.
Trial machining is performed using the tools sequentially, the dimensions of a workpiece
are measured with a caliper or a micrometer, and then those values are entered in the
counter.
