While a spheroid approximates the shape of the earth, a datum defines the position of the spheroid relative to the centre of the earth. Sydney, for example, has a latitude of 33.877° S and a longitude of 151.215° E. In a geographic coordinate system, a point is referenced by its latitude and longitude values ( reference). It includes an angular unit of measure, a prime meridian, and a datum (based on a spheroid). Please, take a look at the video below for better understanding of this option.A Geographic Coordinate System (GCS) uses a three-dimensional spherical surface to define locations on the earth. Collision with chuck/fixture is avoided by defining a Clearance value for the toolpath to stay away from the chuck/fixture.

When the Chuck/Fixture Avoidance functionality in the Advanced tab of Operation Setup Parameters dialog box is enabled and applied to all the operations in the setup then, the toolpaths will be generated after considering the location of the chuck (thereby avoiding possible collisions). Use this dialog box to move or rotate the chuck in X, Y and Z axis direction with respect to the Fixture Coordinate System of the current part so that the chuck is aligned with this current part.įor turn and mill-turn parts, turn toolpaths will now be generated after considering the chuck geometry and chuck location. If the user click on the Edit button opens the Define Chuck dialog box. This functionality is available in the form of the Shape dropdown list in the Chuck/Fixture tab. In previous versions of CAMWorks, chuck shape could be defined only by using/editing/creating an existing chuck configurations.From CAMWorks 2017, the chuck shape can optionally be defined from a STL File or a part/assembly file. For example, I want to present you today two of the most important in my opinnion: define a custom chuck using a 3D model and a much needed function, chuck avoidance. In CAMWorks 2017, there so many enhacements and new functions for turning.
