An issue in manufacturing that is singular to machine builders is the speed with which they can respond with service to the machines, in the case of a failure. In the past, this has usually meant an actual failure has taken place, resulting in a delayed order, scrapped parts, and potentially days of downtime.
When customers require after-sales service, they expect their problem to be solved with minimum delay. Too many service calls require expensive and time-consuming on-site visits.
Service teams are dispatched and repairs / replacement of parts are made, but all of this takes time and creates more delay. As far as being able to predict the need for maintenance, traditional systems meant using the historical information about the machine, or simply establishing maintenance schedules, whether or not they were needed.
Now imagine a world where machines can be monitored remotely, providing an unprecedented service level. What if you had the ability to prove that a warranty threshold was exceeded and you could prove it? What if you could reduce service on-site visits by 10-20%? What if you could see real-time machine data and alert customers about impending issues, before any damage is done to an order is valuable? All of this is possible right now; machine builders require remote access to monitor and assist with user operations to troubleshoot problems, resolve service events and monitor preventative maintenance tasks, all without leaving their office.
“Industry 4.0 software provides analytical tools that help OEMs understand the mechanical factors and environmental conditions that lead to machine failures. Whether it’s vibration, temperature, pressure or other performance indicators, OEMs can use this software to analyze the machine data gathered from their IoT-enabled machines to perform predictive maintenance.” (Source)
In fact, remote machine monitoring, enabled by industrial IoT, is the unique selling proposition that OEM and other equipment providers can offer to their clients, as part of the post sale service package.
“...machine builders can transform their approach to service with the ability to see, understand and take action on their customer’s real-time machine data from anywhere at any time.” (Source)
Reducing downtime, particularly unplanned downtime, is an essential part of keeping costs down and manufacturing levels up. Remote machine monitoring can collect data about the operations of any given unit and transmit that data back via the cloud, enabling machine builders to provide peak level service response time.
While historically, this servicing would require a lengthy and costly on-site visit and possible investigation as to the issues being experienced. A maintenance team would not necessarily be able to detect at a glance which parts were malfunctioning, resulting in a manual process of checking each part. Instead, a remote monitoring system enables machine builders to visualize the issues via the data from anywhere. Troubleshooting even the slightest alteration in a tool path can be done quickly and easily.
Beyond service response is the ability to predict and even prevent breakdowns that severely impact a manufacturer’s production cycle by reviewing and analyzing the data produced. With predictive maintenance, equipment can review available data, detect any exceptions or historical patterns and service the machines in advance of a problem occurring, limiting the impact. It also ensures that a manufacturer need not maintain an extensive inventory of replacement parts, but rather work on a just in time basis.
“Service departments can use data to gain insight into customers’ equipment health and condition, identify maintenance opportunities with analytics and reporting, predict and deliver early warning of potential equipment failures, highlight elevated risk areas that lead to machine downtime, or even take preventative action before it impacts a customer’s machine performance.” (Source)
Challenges with remote monitoring
Industry 4.0, and its vast changes to the way legacy processes such as what many manufacturers will have, bring challenges to the forefront. This is particularly true when dealing with data across organizations.
With so many options, the main challenge remaining for machine builders is to integrate best-in-class solutions quickly and reliably. For example, there are a myriad of PLCs, controllers and sensors available to control machines and track variables like temperature, pressure, or strain. IoT systems need to be able to connect to a variety of Edge devices with proprietary protocols and data formats.
Secondly, most manufacturers have little interest in software companies integrating with their internal networks via ethernet or wi-fi. To that end, many industrial machines were not designed to connect to the Internet and therefore would be exposed over an open network. As a result, many manufacturers do not have the proper security in place to protect data from being stolen or equipment from being hacked.
SaaS platforms—such as MachineMetrics—address all of these issues, including the ability to encrypt data before transfer, leveraging MachineMetrics Edge that allows the transfer of data via Cellular to circumvent a manufacturer's internal network entirely, and an easy self-installed interface with a range of machines, enabling manufacturers to limit their concern about having to use different monitoring solutions on their factory floors.
The ability to identify service opportunities and measure ongoing process improvements, such as ongoing machine health monitoring, is important to after sales service but take innovation a step beyond into the realm of future design specifications!
Machine builders and equipment providers will be able to leverage the data that they receive from their customers to improve on their existing designs or even create better, more enhanced machines because they will have easy access to the data that shows them how the equipment is being used. This presents a huge opportunity for the OEM to ensure that they stay ahead of their competition.
Furthermore, machine builders can use this data to create, manage, and deploy optimized preventative maintenance schedules that are tied to calendar time, usage time, or initiated from machine conditions. Assign maintenance tasks through a workflow, and keep track of customers maintenance to better plan inventory and service needs. This is Preventative Maintenance optimized with Industrial IoT.
With industrial IoT in the mix, the equipment manufacturing industry has an amazing opportunity to provide real value-add to their service packages, making them indispensable to the manufacturers they service.
Companies are starting to offer Remote Monitoring and Management (RMM) for these IoT enabled industrial devices. A key example: MachineMetrics.
MachineMetrics Service is the industry's first AI-driven remote machine monitoring solution designed for CNC OEM’s and Equipment providers; a predictive analytics application on the MachineMetrics Industrial IoT platform that allows service teams to remotely monitor and manage machine assets in the field and at customer sites in real-time. Using MachineMetrics Service, machine builders can see, understand and take action on their customer’s real-time machine data from anywhere at any time.
With MachineMetrics Service, Service managers and technicians can remotely monitor, manage, diagnose and resolve customer’s machine issues for any piece of connected equipment in the field and in real-time using MachineMetrics cellular edge device. The historical and real-time machine data collected allows machine builders to gain insight into customers’ equipment health and condition, identify new service opportunities with analytics and reporting, predict and deliver early warning of potential equipment failures, highlight elevated risk areas that lead to machine downtime, or even determine to take preventative action before it impacts a customer’s machine performance.
Any equipment builder, OEM or distributor, can install MachineMetrics Edge device on a new machine sold to a customer or retrofit any machine currently in the field. MachineMetrics Edge has the ability to connect to the machine’s PLC and any additional sensors into the electrical cabinet of the machine and allows for the data to be shared with the equipment provider. There’s no need to install on customer’s internal IT infrastructure as MachineMetrics Edge comes with included cellular support. Once installed, the provider can add the device to a list of machine assets accessible via the MachineMetrics Service app and associate that machine with the location of the customer. Once the customer receives the machine and powers it on, that machine will appear active on the provider’s list of assets.
Encrypted data is then streamed to the secure MachineMetrics cloud where the data is structured and aggregated to enable visualizations and analytics for service teams to monitor. Access to the historical and real-time data is available through open APIs. Real-time dashboards, historical analysis, and integrations with other systems can be built with these APIs.
The MachineMetrics analytics engine monitors any connected machine’s conditions and other manufacturing data points and initiate an action, such as text notifications when a monitor is triggered such as an alarm state, a limit being exceeded, or any other anomaly in the machine’s health is detected. A rules engine is provided for deploying monitors based on machine condition data and patent pending advanced machine learning algorithms can be deployed for detecting anomalous behavior.
Using this data, equipment service providers can notify machine operators to change a tool before it breaks or even notify maintenance managers when an anomaly is detected that could lead to a breakdown. This ability can prevent thousands of dollars of equipment replacement costs and days of downtime, not to mention unearth new service opportunities that were never visible to service teams before.
Data from thousands of connected machines allow the MachineMetrics Data Science team to work with service teams to identify trends and develop standard preventative maintenance and repair schedules that benefit both the service team and the customers. So while service teams are focusing on addressing issues that may immediately impact their customers, MachineMetrics is keeping an eye on big-picture issues that benefit both the machine builder and the end-user.
“For years now we have been working directly with manufacturers to improve manufacturing equipment uptime, OEE and productivity with real-time machine monitoring and analytics,” said Bill Bither, CEO of MachineMetrics, “By allowing machines to be monitored remotely and in real-time, we are enabling OEM’s to extend these benefits to their customer base while providing them with faster, better service. Our data science team is working closely with the data to deliver optimized preventative and predictive maintenance specific to their machines to improve machine uptime.”
OEM’s are already experiencing the benefits of implementing MachineMetrics Service: “Tsugami/Rem Sales is thrilled to be working with MachineMetrics, bringing cutting edge, disruptive technology directly into our end-users’ businesses,” explained Michael Mugno, Vice President, Tsugami/Rem Sales. “The addition of MachineMetrics Service to our Swiss-turn machine platform packages allows users to collect data on machine health, production status, down-time, and so much more that they may never have known existed - bettering businesses across the industry.”
