Objectives
• Discuss the goal of e-Manufacturing
• Define InterNetworking and describe its
effects on machine tools
• Identify the benefits of extending Ethernet
connectivity to the factory floor
• Define e-Service Portal and list the
benefits of Platinum Maintenance Service
92-3
e-Manufacturing
• About increasing need for communications
– To and from factory floor and customer
• Manufacturers that use machine tools need
to improve productivity by taking advantage
of any new automation technology
• Automation technology key to minimizing
costs and maintaining consistent quality
– Need to automate automation
92-4
Internetworking Standard
• Today, modern machine tools remain closed
islands of automation
– Need to network into enterprise-wide
information system
– Lack of connectivity represents huge constraint
in productivity
• Goal is creation of InterNetworking
standard that makes every machine tool
node on corporate network
92-5
Connecting Machine Tools
• Release information from each machine and
allow management to increase profitability
• Machine tools become servers of information
in real time
• Missing element has been universal bridge
between Industrial Automation and
Information Technology sector
• Open architecture platform being introduced
by e-Manufacturing Networks, Inc.
92-6
CNC Machine Tools
• Dumb islands of technology-not networked
• Made to run only part programs well
• Cut off from management information
system
• Mostly closed embedded systems
• Not being used to full potential
92-7
InterNetworking
• Secure, open architecture platform that turns
every machine tool into node on corporate
network
• Technology of networking tools over
Internet around since mid 1990s
– Hardware and software turns machine tool
controls into Web servers
92-8
InterNetworking
• Web appliance is a machine tool that is a
node and connects point of production to
managements information system
– Real time operations
• e-Commerce changed way we do business
• e-Manufacturing will prove to maintain
rapid rate of change
92-9
Standard Operating System
• Will allow integration with other levels in
corporation
• OMAC (Open Modular Architecture
Controls) Users Groups been working on
open standard since Dec. 1991
– Focus to extend open architecture to CNCs
92-10
Benefits of Extending Ethernet
Connectivity to Factory Floor
• Cost savings in terms of reduced inventory
and operational expense
• Faster production as bandwidth and speed
are increased tenfold
• Improved service as result of remote
diagnostics
– Less downtime
• Better, more informed decisions by
management
92-11
Theory of Constraints (TOC)
• Applied in automated way
• Identifying, monitoring, and optimizing
bottlenecks in value chain process
• Bottleneck in manufacturing
– Operations on factory floor linear, dependent,
and statistically variable in time
– Machining start-stop-wait-repeat process
– Real-time data would eliminate or significantly
reduce wait-periods
92-12
Machine Tools
as Smart Partners
• Concept of an ever-optimizing neural
network onto shop floor
• Bring new class of service
– Remote monitoring done from anywhere
– Diagnostics and parts program recovery done
from any location
– Provided automatically when tool control sends
out alert – self-healing
92-13
Ethernet Connectivity
• Goal to make every machine tool node on
corporate network
• IP address available on Internet
– Identify
– Monitor
– Optimize
• Allows real-time monitoring, remote
diagnostics and 24/7 maintenance via Internet
92-14
Direct CNC Internetworks for
the Shop Floor
• Requires high-speed Ethernet technology
extended to CNC
• Shop floor information systems

Features of the Network
Optimization Product Line
•
•
•
•
Ethernet DNC systems
Ethernet-based Fanuc ® memory upgrades
Ethernet to serial convertors for CNCs
Next generation Ethernet Behind Tape Readers
(BTRs) with memory
• Ethernet-based FMS cell controller solutions
• NT-based remote CNC monitoring software
• Fanuc® Open Systems Interconnection and FTP
Ethernet connectivity solutions
92-16
Benefits of InterNetworking
1. Links e-Commerce (Point of Sale) to
e-Manufacturing (Point of Production)
2. Creates a "Bloomberg-like" real time shop
floor information system
3. Enables remote monitoring, diagnostics
and repair
4. Increase machine throughput up to 55%
5. Better leverages capital invested in
equipment and training
92-17
Internetworking Factory Floors
to the World
• e-Manufacturing networks make machine
tool node on corporate network
• Unique CNC knowledge provide Ethernetbased machine tool connectivity
• NetDNC transforms machine tool into
on-line server of information
• Gives managers ability to monitor and
remotely control via Internet
92-18
e-Service Portal
• Provide diagnostic maintenance for factory
floor in real time
• Platinum Maintenance Service provides

–
Backup of CNC parameters
Fast reinstallation
Notification of downtime
Service requirements
Remote diagnostics
Automatic code repair
Enterprise Resource Planning (ERP)
92-19
e-Commerce Portal
• CNCpartslocator.com (CPL) fastest on-line
source of new and used CNC parts
• Goal to have comprehensive list of CNC
parts to allow finding critical part quickly
• CPL brings together global network of
dealers, suppliers, and OEMs
• CPL able to market to the world
92-20
Summary
• Goal of e-Manufacturing to create
InterNetworking standard that makes every
machine tool a node on corporate network
• Connecting machine tools will release
information and increase profitability
• Adjoining open architecture enable better
flow of information
• CNC tools not used to fullest potential – act
as stand-alones
