Project - Sail Yacht Keel
Larsson & Kjellberg is a well-established company with over 140 years of experience in heavy manufacturing.
When the company chose to invest in GibbsCAM for programming its CNC machines, one of the first projects was to manufacture a keel for "Spirit of Garm IV", a modern reproduction of a fantastic sailboat from 1902. The sheer size and weight of the keel would have been a real challenge for most manufacturers, but Larsson & Kjellberg, being heavy industry machining experts, have the equipment and skills needed to handle this type of monster part. For this machining the GibbsCAM Solids Based Machining options including the 5-axis option were used widely to create efficient and gougefree 3D toolpaths.
Fun fact: Keel weight before milling 12000kg, after milling 6000kg.
