Controller keeps watch on rivetting operations

Orbitform's WatchDawg process monitoring and control system allows visual status and adjustment of the orbital forming process.

Orbitform's WatchDawg process monitoring and control system allows visual status and adjustment of the orbital forming process.

The WatchDawg monitoring/control system ensures consistency and uniformity of orbital formed rivets.

It can precisely monitor and control the forming process, including all aspects of the forming tool and workpiece.

Orbitform's WatchDawg System features the ability to monitor and control: minimum/maximum forming force achieved and variable rate of forming force; forming to a given height, fixed or variable position at programmable speeds; form to a resulting clamp load between the parts being fastened together; and load cell force up to 9t based on machine capacity.

The WatchDawg interface provides comprehensive feedback with data easily integrating into automated systems.

Multiple programs can be stored to allow for quick changeover from application to application.

At the heart of the system is a load cell mounted inside the powerhead of the spindle assembly.

The load cell measures forming force applied to a part.

Depending on machine size, a linear displacement transducer (LDT) or linear encoder is integrated into the powerhead and used to measure stroke.

These sensing devices determine form depth and position at peak force.

Benefits include easy calibration, fast response, smooth production line integration, and the ability to keep fixturing interchangeable.

The system monitors rivet/form collapse and rivet length through set point limits.

It tells how much of the rivet has been formed and if the load cell trigger point is met.

The system also controls by forming-to-a-force, commonly used on pivoting joints or parts that need only to be tight.

This feedback closes the loop between powerhead and part.

The WatchDawg monitoring/control system offers: precise process monitoring with unlimited process control; high repeatability and reliability; the ability to form parts from 0.06 to 2in diameter; an easy-to-use touch screen with familiar controls; pressure differential process control to form to a prescribed clamp load; and a programmable z axis to vary stroke.

Orbitform's WatchDawg monitoring/control system delivers dependable feedback for manufacturing and assembly processes.

It's an application-specific process philosophy that brings orbital forming closer to an exact science.
