| Summary: | Cable excavation is a work that becomes expensive as it is time consuming and the risk of cable breaks is imminent. It often happens when the excavator is used in direct contact with the cable strap. The purpose of the work is that Holms is in a product expansion phase, which in turn means that they want to manufacture more tools for excavators. The aim is to produce a CAD model and manufacturing base for a first prototype of a so-called cable brush machine. The work is being carried out at Holms Industri located in Motala, which today designs and manufactures road maintenance tools for mainly tractors and wheel loaders. The method is based on Ullman's product development process, which was modified to suit this work. The concept development was divided into two phases where the first phase became rough sketches of how the cable machine could look. The result from the first phase was taken to the second phase, focusing on making the concepts more detailed in order to progress. The detailed design of the prototype began with the definitive concept as a base. To minimize the requirement for welding fixtures, reducing production time and achieving consistent results the focus was on making the details easy to produce and assemble. Manufacturing bases were then created from the CAD models. The result of the work became a prototype of the cable brush machine, made with 3D models and manufacturing bases to build and test it.
