Yes. Multiple EDM machines can work together in one manufacturing line—but simply placing several EDM machines in the same factory is not the same as operating them as one coordinated production system.
When several EDM machines are running different jobs, manufacturers must coordinate work orders, electrodes, workpieces, machine availability, robotic handling, inspection, and the next production process. If all of these decisions still depend on operators moving between machines, production can become increasingly difficult to manage.
A Flexible Manufacturing System (FMS) provides another approach. By integrating multiple EDM machines with centralized production control, robots, electrode and workpiece storage, and inspection equipment, manufacturers can manage several machines as connected production resources rather than isolated equipment.
For precision mold, automotive tooling, aerospace, energy, electronics, appliance, transmission, and other high-value precision manufacturing environments, this becomes especially useful when different jobs must move through different processes.

Operating two or three EDM machines at the same time is technically straightforward. The real challenge appears when the number of jobs, electrodes, and workpieces increases.
Production teams may need to answer:
If each EDM machine is operated and scheduled independently, these decisions rely heavily on manual coordination.
The problem becomes even more noticeable in high-mix manufacturing, where the next job may require a different electrode, workpiece, machining program, inspection requirement, or production route.
Instead of asking only whether multiple EDM machines can run simultaneously, manufacturers should therefore ask:
Can our EDM machines share a coordinated production workflow?
A Flexible Manufacturing System connects multiple pieces of equipment with production management and automated material handling.
In a multi-EDM environment, the basic concept can be represented as:
Workpiece Storage → Robot → EDM A / EDM B / EDM C → Cleaning → Inspection / CMM → Next Process
The workpiece does not necessarily follow one fixed path. Different jobs can be assigned to different machines or downstream processes according to their production requirements.
OSCARMAX's Multi-EDM Flexible Manufacturing Line with Inspection Station demonstrates how multiple EDM machines can be integrated with workpiece storage, electrode magazines, robotic handling, washing, inspection, CMM, and centralized control.
In a conventional setup, operators may schedule each EDM individually.
This works when the number of machines and jobs is limited. But as production becomes more complex, machine-by-machine scheduling makes it more difficult to maintain an overview of the entire workflow.
With centralized production management, manufacturers can manage work orders and machine status from a broader production perspective.
Instead of asking:
“What should EDM No. 2 do next?”
the system-level question becomes:
“Which available machine is appropriate for the next job?”
This distinction is important. An FMS is not simply designed to make one EDM faster—it helps multiple machines operate within the same production plan.

Electrode management becomes one of the biggest challenges when multiple EDM machines are processing different jobs.
This is especially common in precision mold manufacturing, where one mold may require multiple electrodes for different:
Now imagine several mold projects running simultaneously across multiple EDM machines.
Operators not only need to know which machine is available; they also need to make sure the correct electrode, workpiece, and machining job are matched.
Integrating an electrode magazine and workpiece magazine with robotic handling helps organize this flow and reduces repetitive manual searching and transportation.
Manufacturers looking for precision die-sinking solutions can also explore OSCARMAX's Die Sinker EDM range, including the EX Series.
A multi-EDM manufacturing line should not stop at the EDM machines themselves.
After EDM machining, some workpieces may require cleaning, dimensional inspection, or another manufacturing process.
When every transfer depends on an operator, additional waiting and manual coordination can occur between processes.
An integrated FMS can incorporate robots, washing stations, inspection stations, and CMM equipment into the production route.
For example:
EDM A → Cleaning → CMM
while another job may follow:
EDM B → Cleaning → Next Process
This flexibility is particularly valuable when manufacturers produce different components rather than repeating the same part continuously.
The most important difference is therefore coordination, not simply automation.
Not every manufacturer needs several EDM machines connected through FMS.
The strongest applications are environments where multiple jobs, electrodes, workpieces, and process routes must be managed simultaneously.
Precision mold manufacturers are one of the clearest applications.
Several mold projects may be running simultaneously, and each mold may require numerous electrodes. Integrating multiple EDM machines helps manufacturers coordinate different workpieces and machining stages within one production workflow.
Automotive tooling suppliers may handle multiple lamp molds, interior molds, door-related tooling, or other projects with different schedules.
When several EDM machines are involved, centralized coordination makes it easier to manage changing project priorities.
Aerospace manufacturing often involves high-value components, different job requirements, and inspection processes.
When multiple EDM machines are combined with robotic handling and CMM inspection, manufacturers can create a more controlled and traceable manufacturing flow.

These industries may also benefit when production involves:
The deciding factor is not simply the industry—it is the complexity of the manufacturing workflow.
Not necessarily.
Some manufacturers may only need one EDM connected with a robot and electrode storage. OSCARMAX's Modular EDM Automation Cell with Robot and Electrode Storage demonstrates this smaller-scale approach.
A multi-EDM flexible manufacturing line becomes more relevant when:
Manufacturers can explore different configurations through OSCARMAX FMS Cases.
Multiple EDM machines can absolutely work together in one manufacturing line.
But the key is not simply running them at the same time.
The greater value comes from integrating multiple EDM machines, work orders, electrodes, workpieces, robots, storage, cleaning, inspection, and production information into a coordinated workflow.
For manufacturers whose production has become too complex to manage machine by machine, FMS provides a way to move from several independent EDM machines toward one connected manufacturing system.
