The purpose of this Thesis is to investigate how to automate a process of masking details before painting. Masking is one of the most important phases in paint preparation and can be executed in various ways, depending mostly on type of product and on demands to parts which should be masked. This work addresses the certain process of masking lifting arms at VBG GroupTruck Equipment AB. This masking process basically represents a coupling of two parts together (lifting arm and rubber mask) and is simple to be executed manually. However,a large amount of repetitive work goes against ergonomics and effective utilization of human resources. Some of renowned benefits of automating process by means of robots are those considering, among others, elimination of monotonous work and process performance improvement. On the other hand, often it appears that operations which seem simple to execute by human become complicated for machines, and some level of human participation in a process still might be needed. Summing up, the solution for automating the masking of lifting arms should cut toa minimum (if not eliminate) all manual operations, and to be applicable for similar typeof work wherever possible.
