Hello everyone, I am UG programming teacher An. Today I will share with you the " CNC machining center , CNC lathe programming learning tutorial case". For friends without a foundation, this learning content is very suitable and the content explanation is very thorough. I hope it will be helpful to everyone in their study and study. While studying, don’t forget to collect it, you won’t find it next time!
Next we officially enter today's content: CNC lathe programming example
example 1. G01 linear interpolation instruction programming as shown in the figure below
Installation and installation of contour workpiece
Please set up installation of contour workpiece, reference for each point coordinate is as follows (X direction margin 4mm)
