Thermal Spray Toolkit is a developing toolkit for thermal spray applications based on RobotStudio™ software which is developed by Asea Brown Bovrie Ltd (ABB). This toolkit is composed of several functional modules including PathKit, ProfileKit and MonitorKit. PathKit provides numerous methods to create trajectory on different surfaces including square and rectangular surfaces, round surfaces, curved surfaces and rotating workpieces. ProfileKit permits coating surface analysis by importing a surface profile and it can also guide users to select the right spray parameters according to specific materials. MonitorKit can capture the robot displacement in real-time during the spray process. Thermal Spray Toolkit is a toolkit developed to apply robotics in thermal spray applications whose reliability has been confirmed by the experimental results.
