After the completion of my new CNC conversion unit for my LMS 3900 Hi Torque with all of the necessary testing completed, I found the only task at hand is the requirement of a CAM gcode post processor. Judging by advertisement videos the big 3d parasolid CAM software are very good and proficient at the correct layering and custom toolpaths. They are very expensive. Looking at the nominally price software, they can do the job with some limits on custom 3d contouring etc. I am very proficient in reading gcode and correlating to graphical toolpaths. The nominally priced software are very affordable, but they are too easy to match by custom programming using Visual Basics. The requirement of importance for choosing or making yourself a CAM program is as would just like a professional hand machining job who can turn out perfect accurate finished parts in terms of gcode towpath that match the path, feedrate, and spindle rpm. Layering step down customization as well as feedrate customization is important as well as to implement with most required CAD dxf or similar graphics files. Mach 3 wizard are superior but only alllow for certain operations. They are very easy and sound working as evidence by the turned superior turned out parts. For custom shaped parts one would require a 3D CAM program with vector graphic import and post processor capability. My new project entails for now a field based with Win 7 forms style the ability to take basic lazycam converted gcode and make multiple step down layer with variable feedrate with field ranges and static graphical representation in CAD form. It's a very simple and small program. Due to the immense amount of gcode lines this program will be designed to Cartesian axis coordinate plug in and repetition additional lines reliably to be uploaded to MACH 3 for checking and trial run on test composite and end mill. I would like to program this software for real life toolpaths that produce a highest quality part without excessive preparation. It is a extension in function of wizards type . After analyzing VB capabilities, it looks a though the program can be simply framework and built without complexity. I decided to stick with VB and VC++. This program should handle all my CNC machining needs. Uncertain how long it will take but it should be soon.
