Calling tool data
A TOOL CALL block in the part program is defined with the following
data:
8 Select the tool call function with the TOOL CALL key.
8 Tool number: Enter the number or name of the tool.
The tool must already be defined in a TOOL DEF block
or in the tool table. The TNC automatically places the
tool name in quotation marks. The tool name always
refers to the entry in the active tool table TOOL.T. If
you wish to call a tool with other compensation
values, also enter the index you defined in the tool
table after the decimal point.
8 Working spindle axis X/Y/Z: Enter the tool axis.
8 Spindle speed S: Spindle speed in rpm
8 Feed rate F : F is effective until you program a new
feed rate in a positioning or TOOL CALL block.
8 Tool length oversize DL: Enter the delta value for
the tool length.
8 Tool radius oversize DR: Enter the delta value for
the tool radius.
8 Tool radius oversize DR2: Enter the delta value for
the tool radius 2.
Example: Tool call
Call tool number 5 in the tool axis Z with a spindle speed of 2500 rpm
and a feed rate of 350 mm/min. The tool length is to be programmed
with an oversize of 0.2 mm, the tool radius 2 with an oversize of
0.05 mm, and the tool radius with an undersize of 1 mm.
The character D preceding L and R designates delta values.
Tool preselection with tool tables
If you are working with tool tables, use TOOL DEF to preselect the next
tool. Simply enter the tool number or a corresponding Q parameter, or
type the tool name in quotation marks.
