Pilot study for automation of grinding process (English)
Abstract [sv]

Detta examensarbete har utförts på Ovako Bar i Hällefors i syfte att kontrollera möjligheterna att automatisera en slipningsprocess på stänger med ytdefekter. Det största skälet till arbetets uppkomst är de vibrationsskador som uppstår i operatörers händer vilket i sin tur leder till sjukskrivningar.

Arbetet inleddes med en nulägesanalys på Kontrollstation 7 för att kontrollera hur processen går till, hur operatörerna upplever situationen och få en större förståelse för situationen. Information om nuvarande utrustning inhämtas i syfte att kunna utvärdera möjligheter. Kontakter med potentiella leverantörer togs också, i syfte att få ytterligare bollplank.

Efter nulägesanalysen inleddes förbättringsförslagsprocessen. Lösningar till problemet uppkom ur brainstorming efter kravspecifikationen. De lösningar som blev godkända skickades ut till diverse leverantörer som tidigare kontaktats för vidare idéutbyte och möjlighet till utförande. De leverantörer som kontaktades var IM Teknik och Robotslipning AB.

Investeringsanalysen visar att lösningen ”robotslipning med visionssystem” är den mest kostnadseffektiva för att uppnå de krav och önskemål som skulle uppfyllas.

Abstract [en]

This thesis has been carried out on Ovako Bar in Hellefors in order to check the possibility of automating the manual grinding process on bars with surface defects. The biggest reason for the occurrence of this thesis is the vibration damages in operators' hands, which in turn leads to sick leave.

Work began with a current situation analysis of KS-7 to observe how the process works, how operators perceive the situation and get a better understanding of the situation as well as acquiring information on the current equipment. Contacts with potential suppliers were taken as well in order to obtain additional exchange about the potential products.

After the current situation analysis the improvement suggestions phase took place. Solutions to the problem arose out of brainstorming according to the specifications. The solutions that were approved were sent to various vendors for further exchange of ideas and the possibility of execution. IM Teknik and Robotslipning are the companies that were contacted.

Investment analysis shows that the solution with robotic grinding with vision system is the most cost efficient to meet the demands and requirements to be fulfilled.
