This allows you to align your tool with a User Coordinate System in the model. This allows you to choose the X & Y axes yourself, using the model geometry. This allows you to choose the Z & Y axes yourself, using the model geometry. This allows you to choose the Z & X axes yourself, using the model geometry. Your tool will align with the axis of the Work Coordinate System associated with the active model. Your tool will align with the axis of the Work Coordinate System associated with the active setup. This functionality allows you to select the orientation in a few different ways. Tool orientation once turned on allows you to orientate your tool, so that you can machine your component or feature at an angle that differs from a 3-axis orientation. It sounds trivial, but it was worth mentioning just in case! The first thing to be aware of, is that this functionality will only work if you have 5-axis functionality on your machine tool. As you may know, this can be found within many of the toolpaths within Fusion 360. Let’s now look at the Tool Orientation functionality. This will make this a simpler and more intuitive process. A lot of people tend to use either the centre of the stock or a corner as their reference. This means your toolpaths will be shifted by the distance separating your G54 and your WCS. If the Work Coordinate System and your G54 on your machine do not match up, when you output your toolpaths to the machine, the machine will be referencing your strategies to a different coordinate system. This MUST match your reference point on the machine, such as G54, G55 etc. The Work Coordinate System is what you must define in your setup. In the first part, we’ll look at Work Coordinate Systems, or WCS for you Fusion 360 fans. I will separate this blog into two halves. A common question we get asked about Fusion 360 is “What is the difference between creating a new work coordinate system and defining a tool orientation for a positional axis-move?”.
