Human machine interface’s goal is to make it easy (self explanatory), efficient, and enjoyable (user friendly) to operate a machine in the way which produces the desired result.

Why It’s Time to Consider Using Vision Technology

coffee_robot_3D_modelBecause the use of vision technologies on the plant floor can give you a competitive advantage, here are the key issues to consider when looking for the right vision system.

How viable is vision technology on the plant floor? On the surface, when you look at the technology and the capabilities it seems like vision should be as common as the programmable logic controller (PLC) and the human-machine interface (HMI). If you think about the technology and its ability to “see” the environment and make decisions based on what it sees, the applications are boundless. Despite its clear advantages, the use of vision technology on the plant floor is not as commonplace as most people would imagine. Why is that?

I believe the main reasons are: 1.) The supporting technology behind the camera; and 2.) Camera installations are often viewed as being not very robust. Continue Reading →

Human Machine Interface (HMI)

An interface that permits interaction between a human being and a machine. Human machine interfaces vary widely, from control panels for industry to the screen and input buttons. Designing such interfaces requires a great deal of work to make the interface functional, accessible, pleasant to use, and logical.

Control Upgrades Give Peening Machines a Shot in the Arm

Boeing has learned first-hand how a control-system upgrade can make an old machine work like new, at a fraction of the cost of purchasing a new machine. Case in point: recent refurbishing of four shot-peening machines at the Boeing Fabrication Division plant in Auburn, WA. The Boeing fabrication shop uses spanwise peening machines for contouring wing components, and compression peening machines for cold working. Early in 2011, plant managers decided to upgrade the machines’ controls, which ranged from 20 to 40 years old. Some used relay logic and some were CNC-based. Parts had become obsolete, and maintenance had become overly expensive.

The plant’s managers sought new controls that were more process-oriented, and simple-to-use human-machine interfaces (HMIs) standardized with operator controls used at other Boeing plants. To help with the upgrades, Boeing turned to Concept Systems Inc. Albany, OR, and its engineer Jim Ford, who proposed replacing the old CNCs with Allen-Bradley PLCs. In addition, he recommended Allen-Bradley Panel View terminals to provide the graphics displays. The old DC servos were replaced with smaller AC servomotors and new gearboxes were installed to upgrade the mechanical aspects of the machine. Continue Reading →
