- The document discusses different tool identification systems that the presenter's company has experience with, including read-only and read/write systems. - With read-only systems, tool data is stored centrally and retrieved via the machine's network connection when a tool is read. With read/write systems, data is written at a tool presetter and read locally. - Examples of implementations involve Balluff read-only tags, storing data on an SQL server, and retrieving data automatically on machine load for tool size offsets. The presenter is available to further discuss options based on a customer's specific needs.

1. Presented by :

2.  We have been working with Tool I.D.
systems since the start of the company 21
years ago.
 We have worked with vendors such as
 Balluff
 Peppler & Fuchs (P&F)
 Nedap
 Omron
 We have designed control interfaces to many
of the CNC controls on the market.

3.  CNC controls
 Most of the Fanuc and GEFanuc controls
 Okuma
 Mazatrol
 Mitsubishi
 Allen Bradley 9/series
 Haas
 We have worked with read only, read / write,
and bar code tool I.D. systems

4.  Two basic methods
 Read Only
 Read / Write
 Both types require
RS232 or ethernet
communications
 Controller can read
multiple heads if
required.

6.  CEI interface connects to network and
communicates to Central Data Storage
 CEI interface connects to CNC control via
serial, parallel, ethernet or software only
 The system requires a networked central
database
 The central database and netwrok must be up
and running at all times to allow data
retrieval

7.  Tool I.D. is read at the machine
 Local controller queries the central data
storage for tool information linked to this I.D.
 Length and diameter offsets are sent to the
CNC control for this tool
 A local display can query the operator for tool
offset location

8.  Advantages  Disadvantages
 Lower cost  Requires a network
 Status of each running at all times
machine is available  Tool information
via network at all must be retrieved
times from network
 Tool life can be  Tool data
viewed at any time unattainable if
network is down
 Requires a central,
managed, database

10.  Tool information written at presetter
 Tool installed at machine
 Tool information read by local controller
 Length and diameter sent to machine
 Flag can be set in tool I.D. chip specifying the
tool is used

11.  Advantages  Disadvantages
 No network required  Higher initial cost
 New information can per I.D. chip
be changed at the  Information not
machine available at the host
 Tool information can or network server
be read at any remote
station
 Does not require a
central database

12. • All tools have a Balluff Read Only
ID tag installed
• The tool presetter measures length
and diameter and writes the values
to the SQL server on the plant
network
• Data is stored by the unique
identifier on the Balluff ID tag
• The tool information is then
retrieved when it is loaded in to a
machine

13. Each machine has a tool read pot
mounted outside of the tool change
door
When the operator is ready to load a
tool in the machine they insert it first
in to the tool read pot
When the tool ID read head senses
that a tag is present, the tool load
application automatically pops up on
the Okuma control or PC on Fanuc
control with Focas1/2

14. Using the unique identifier on the Balluff ID tag, all of the
tool information is retrieved from the database
• If the tool is OK to use the
Tool can be loaded in to
the magazine
• The following conditions
Tool Life Mismatched
Tool inis Expired–Error
Tool Missing –– Error
Tool Tool is SetError
Spindle won’t allow the operator
to continue with a tool
load sequence
• If the Tool is not in
the database
• If the tool life is
expired
• If the tool is in the
spindle
• If the tool does not belong
to the current part
program a mismatch
warning occurs

15. •This is a random access tool
changer so the tool to pot
correlation is constantly changing
•On Okuma P controls and Fanuc
controls with Focas1/2 we can find
which pot is associated with the
tool number that is going to be
loaded
•Our software then brings that pot
to the tool load door making it easy
and fool-proof for the operator to
load a new tool

16.  On Okuma P controls all of the applications
reside in the control and are a software-only
solution
 DNC-2 or Ethernet option on Fanuc control
 Allows data to be transferred at any time
 Part programs can be transferred in the background
 Probing data can be retrieved at any time
 PLC via direct I/O
 Requires additional machine inputs and outputs
 Requires re-programming of controls PLC

17.  Most systems to date have used the Parlec or
Zoller presetter
 Basic P.C. software can be easily setup to read
and write to tool I.D. chip
 Any presetter can be used as long as it
provides some type of output preferably
RS232 or ethernet

18.  Read Only or Read/Write ID technology?
 Which tool presetter will you use?
 Where will the tool be read at each machine?
 What CNC controls will be part of the
system?
 If read only, who will maintain the database?
 Do you have stable plant wide network?

19. We have extensive experience in many different forms of
tool identification systems. Typically, we have
customized each system based on customer
requirements. If any of the tool I.D. systems described
is of interest, we are available further review of your
requirements.
