Abstract [en]

One of the most fundamental manufacturing processes is the simple bending of rods and wire. Although a simple process, when performed manually it can become a burdensome and repetitive workload with scattered results. Automation today has allowed these kind of processes to be automated, although the machines can be complicated to program.

This report contains the construction and result of a machine capable of feeding, bending in three dimensions and cutting steel wires with diameters up to 1 mm. Furthermore the functions of the machine are managed with a handheld controller where the operator has the ability to control and record objects to be produced. The projects resulted in a wire bender that fulfills the goals of the project. It was noticed that some large error in angles occurred between the original model and the copies of it. Therefore the repeatability is quite poor while the precision in the copies is considerably better.

Abstract [sv]

En av de mest fundamentala tillverkningsmetoderna är bockning av stänger och tråd. Även om det är en simpel process blir det ett betungande och repetitivt arbete om det utförs manuellt med spridda resultat. Automation idag tillåter dessa typer av processer att blir automatiserade, dock kan maskinerna vara komplicerade att programmera.

Denna rapport behandlar konstruktion och resultat av en maskin kapabel till att mata fram, bocka i tre dimensioner samt kapa ståltråd med en diameter upp till 1 mm. Maskinens funktioner styrs med en handkontroll. Med den kan operatören även spela in former för att sedan ha möjligheten tillåta maskinen reproducera dessa. Projektet resulterade i en trådbockare som uppfyller de mål som satts upp för projektet. Det noterades att det existerade fel i bockningsvinklarna mellan orginalmodellen och dess kopior. Därav kan repeterbarheten sägas vara dålig medan precisionen i kopiorna var betydligt bättre.
