3 Differences from standard T/M-system controls
Some turning and milling features of this function are different from the
standard T/M-system controls’.
This chapter explains the details.
3.1 Tool selection, tool offset
When T code is commanded, the code signals and strobe signal are to be
output for a machine to select a tool.
T code command for standard T-system control specifies a tool offset and
validates it at the same time as well as tool selection.
Therefore, this standard type specification is not suitable for an automatic
tool changer usually used for a machining center.
Compound machine function has a parameter to select whether this
standard one or M-system tool selection type even in turning mode.
3.1.1 T code command
The parameter setting of TM6(No.xxxx#x) = 1 allows you to change tools not
by T code only but M06 code.
The first 2 digits(max. 6 digits) of T code command show tool number and
the last 2 digits show tool offset number.
Too**
oo: Tool number
Output to PMC(F0026#0 - F0029#7)
Used for preparation of the next tool
**: Tool offset number
Output to macro variable(#xxxx)
• T code should be used for indexing tool and M06 for starting to change tools
• Movement for tool offset does not start only by T code command. It requires
G code to activate
• When parameter TM6 is set to “0”, tool change is done with T code.
• When parameter TM6 is set to “0”, parameter 13001#1(TO2) must be set
to “1” tool change is done with T code. As for TO2, please see the next
chapter.
• The thing used cannot be done by switching standard T code command and
this method at any time.
• The tool changing command is the same as it of standard M control.
