BIAS cutter control system retrofit

The buyer's problem

Card-based DC servo controls and aging machine electronics can limit cutter accuracy, speed and supportability in demanding tire production. A retrofit must preserve essential machine geometry, setup knowledge and downstream coordination.

What we replace

• Obsolete card-based DC servo control with a PLC-based AC servo control architecture.
• Legacy control, electrical and pneumatic components where condition and engineering review call for replacement.
• Aging operator interface with a dedicated HMI for operation, process data and recipe management.

What we retain where suitable

• The cutter frame, material path, tooling and plant connections where condition permits.
• Machine setup, cut recipes and operator knowledge captured before controls migration.
• Existing conveyor and line coordination where suitable for integration.

Control platforms

• PLC-based AC servo controls, with PLC, AC servo, VFD and HMI systems on a local network (documented in the matching BIAS cutter case study).

Validation deliverables: FAT through PQ

Deliverables and responsibilities are agreed with your engineering and quality teams. PQ approval remains with the equipment owner.

• FAT: production/quality-agreed motion, cut-rate, accuracy, safety and HMI test protocol with results and deviations.
• SAT: integration, machine-operation and plant-interface acceptance report following installation.
• IQ / OQ: agreed installation records and functional/operational test evidence for the retrofit; formal pharma-style qualification is used only if required by the customer.
• PQ: support customer-defined production-trial protocols, results and acceptance records; production release remains with the equipment owner.

Matching project experience

The case study reports a 20% increase in cuts per minute, control-system uptime above 99% and increased position accuracy for cutters and conveyors.
