Programming Tutorial for Computer Aided Manufacturing
Friday, December 4th 2009
Two weeks before I write this entry, I was busy researching how to make a Computer Aided Manufacturing (CAM) software for controlling a 3-axis Milling Computer Numerical Control (CNC) machine. While this particular task is challenging, I later find that solving this problem is actually as difficult as motivating myself to start solving it. Since there are lots of things that need to be learned before a CAM software can be made, this subject will be explained part-by-part with this post as the index page.
Tool Geometry Function - A CNC machine will need to use various tools to turn a raw material into the desired shape. In order to enable a Computer Aided Manufacturing software to properly use these tools, their geometry must be defined as Tool Geometry Function ( ZTool(r) , r = distance from tool center ).
Target Surface Function and Tool Guiding Function - If we want to turn a raw material into a shape we desire, we need to define the geometry of that shape. After the target surface geometry ( ZTarget(x,y) ) had been defined, we have to calculate the Tool Guide Function ( ZGuide(x,y) ) which represent how deep a particular tool is permitted to penetrate the material.
The basic G-Code - G-Code is the programming language that a CNC machine have the capability to read and execute. Basically the purpose of a CAM software is to write a file in G-Code that later sent to a CNC machine to execute.
Since this particular post is going to serve as the index page for Programming Tutorial for Computer Aided Manufacturing, the post is going to be updated as new entries about the subject are added.
