Manufacturing services

James Fisher Nuclear manufactures, assembles and tests all equipment and systems supplied either in-house or with support of international supply chain. 

For each individual project a specific manufacturing strategy is selected by James Fisher Nuclear (JFN) as part of the project delivery planning process to ensure that the cost and quality required by the customer is delivered. You can be confident that the make or buy decisions are informed by our highly experienced manufacturing services teams and our supply chain specialists. Extensive use is made of carefully selected standard components which support the reliability and maintainability of the finished product. Where a specialist capability is required, off-the-shelf subsystems will be integrated to deliver a complete system.

CNC programming is used to define the material type, stock material size and tools to be used.  To eliminate transcriptional errors there is no manual input of dimensional data and direct transmission of machine code to the machines. Machining cycle times are calculated automatically.

Automated tool setting routines are used to select the correct tool, load the tool turret and select the tool tip without the requirement for operator input. The machining is followed, without removing the component from the machine, by an automated inspection process using electronic probes. The automated inspection process allows for compensation for tool wear and helps reduce component lead times.

Engineering requirements planning (ERP)

  • Data for every part used is stored and linked by a bill of materials for each assembly
  • Production resources required for the manufacture of parts and the routing of those parts to each resource is also entered
  • Benefit of this system for one off jobs is that it provides the base data for the allocation of stock material, material ordering, material traceability, engineering change control, capacity planning and the reporting of shortage lists
  • For repeat orders, data can be used to automatically generate material orders and works orders on individual bills of material, or through manufacturing requirements planning (MRP), if there are many of the same parts being used by a number of orders
  • Significant savings in product management time result

Production planning

  • When there are many orders for assemblies having some common parts, the MRP system enables works orders to be grouped so that all common parts can be put onto the same works orders and minimise CNC set up operations
  • All works orders can be loaded onto the appropriate resources and the effect can be assessed using infinite and finite capacity planning
