Tool Call - HEIDENHAIN POSITIP 880 User Manual

Tool Call

The TOOL CALL is used to select a specific tool number from the tool
table at run-time, for instance during a program. The block specifies a
tool number and an optional tool axis. See Fig. I.42.
Calling a tool
Refer to Job Setup for how to enter the length and diameter of your
tools in the tool table.
The TOOL CALL command automatically pulls the tool length and
diameter from the tool table.
You may define the tool axis for the program run in the TOOL CALL
block.
Tool axis setting
A tool axis is selected to define the machining plane. Tool radius
compensation is applied to the axes forming the machining plane. Tool
length compensation is applied along the tool axis.
For example, a horizontal boring machine may have machining
features such as hole patterns located in the YZ plane. The boring
operations are performed in the X axis. For this configuration, the tool
axis would be set to the X axis.
Press the TOOL AXIS soft key.
Select the tool axis with soft key.
Press USE.
When you execute a tool call block with a new tool axis,
this tool axis will remain in effect until you select another
from the tool table or another tool call block.
