The Basics of Computer Aided NC ProgrammingLaajuus (3 cr)

Objective

Students will know how to use CAD 3D applications and to programme machining paths based on generated geometry in order to produce NC programmes for numerically controlled machining tools.

Content

Stages of computer aided NC programming
Transfer of data from the design system to the NC programming system
Creating 2D machining paths
Simulation
Subfile and post processor processing
Testing the produced NC programme with an NC machine

Assessment criteria, excellent (5)

The students are proficient to a high standard in the basic terms and stages of computer aided NC programming. They are able to compile machining paths independently for more complex parts. The students are able to select tools and calculate machining values reliably. They are able to analyse whether the produced NC programme is correct and can check the results of their work. The students are able to work so that the NC programme can be reliably transferred to the NC device for piece machining.
