Objectives and Approach

The objective of this project is to automate the polishing of castings with the use of advanced robot and sensor technology.

The quality requirements of many polishing processes are very strict, demanding a high degree of human skill and attention. The work is strenuous, noisy, dirty and uninteresting. Workers are exposed to hazardous environments and to machine vibration. Automating the process will lead to lower production costs, higher productivity and more uniform product quality.

A grinding station composed by two interlinked robot cells is under development.

The robot grinding cell will comprise a 6-axis process robot and a grinding tool set. Based on off-line analysis of the parts geometries (curvature) and appropriately selected grinding wheels robot programs will be derived.

The inspection cell will comprise a 6-axis robot which will be used to present the processed part to the camera for inspection. The inspection paths will be automatically derived with the use of off-line programming tool in combination with appropriate part modelling.

The inspection will be based on image analysis software designed to meet the specific requirements of the problem. A special designed parallel image processing hardware will be used to run the inspection software. Image acquisition will be performed by an autofocusing sensor head with automatically controlled lighting.

The whole cell will be controlled by a real-time software (a task manager) which will link and control all the cell operations from a single computer. System performance data and other statistics will be gathered and displayed at that level.
