I. INTRODUCTION
The au oma ic ool eadjus men unc ion is abb e ia ed
ATR. This unc ion is speci ic he Flexible Manu ac u ing
Cell le els and Flexible Manu ac u ing Sys em le el and is
ask is o p epa e a new se o ools in he s o age sys em o
he machine o he nex i em o be manu ac u ed while he
cu en i em is being manu ac u ed [1].
F om he poin o iew o he equipmen needed o
pe o m he unc ion ATC he e is a g ea a ie y o solu ions
acco ding o ealiza ion o ATR unc ion. The usual solu ions
depend on he ype o ATC and is based on he le el o
machine used.
The TMA 55AL (Fig. 1) has been upg aded o include an
ATR unc ion. The solu ion used is based on a ool s o age
uni accessible o he ool change o he wo k cen e.

The ool s o age uni accessible o he ATC is loaded in he
machine using he sys ems APC unc ion, and is based on a
ombs one de ice.
The s eps necessa y o implemen he ATR unc ion a e:
 De e mining he lis o necessa y ools o he nex

 Making he equipmen and de ices necessa y o

 Making and in eg a ing he speci ic so wa e

II. THE TOOL SELECTION
The ATR unc ion mus ealize he physical ans e o he
ools be ween he cen al s o age uni and he ATC s o age and
also make he necessa y upg ade in he ool lis s (ATC ool lis
and in he lis o ools a ailable a FMS le el).
In o de o be able o ope a e changes in he ool lis o he
ATC which is managed by he Fanuc so wa e on he 310i
CNC he codi ica ion o he ools and all o he in o ma ion
ha a e necessa y o be “deli e ed” wi h he ool mus be
known.
Fanuc 310i CNC equipmen machine allows he ool
selec ion by calling he T add ess. The o m o ool add ess
can be se so ha i includes in o ma ion on he numbe o he
ool and he posi ion o he o se o each ool in he o se
able. The pe mi ed al e na i es a e p esen ed in able 1.

These da a a e gene ically called ool managemen da a.
