Viesturs, I was able to do it through Sheetcam (http://www.sheetcam.com/) and slightly customizing the post for some special conditions required for use with an ultrasonic knife. I expect Leslie Newell will chime in on this, as it does require a special post which I do not believe is included in the standard distribution of sheetcam.
Regards, Eric Hello! I found this in older archives (please, see below). I was wondering, if this has been implemented and there is some sample preprocessor that i could find? I find this very crucial as this option could save me several thousand usd for specific waterjet cam software as this function would allow very simply implement waterjet taper compensation and i believe that it would be crucial to anyone else, who would like to retrofit their older waterjet cutting equipment and upgrade to 5 axis machine. The way to use this tool: 1) with XYZBC setup of waterjet machine, i set proper B angle to tilt the cutting nozzle perpendicularly to cutting edge to compensate for the taper and 2) with this tool i would have C axis turn as needed to keep the tilting angle correct in respect to moving direction as the tilt direction has to be perpendicular to the moving direction at all times. So has there been any progress on this matter during last year? Thank You in advance! with best regards, Viesturs Date: 2009-01-28 17:15:59 GMT Mario. wrote: > So I understand it correctly that a wheel-cutter mode is now in > ideological development, right? > That's some great news! > After some discussion, it seems the consensus is that there is rather little development to be done. The C axis (for cutter angle) will just be another axis on the machine, so EMC, itself, needs no change. What does need to be done is create a filter program that takes in G-code with XY commands, figures out the cutter angle and adds in a C command word. For any G01 moves, the calculation is trivial. For instance : Input file, currently at X0 Y0 : G01 X1 Y1 Output file: G01 C45 X1 Y1 So, it sets the cutter angle first, then performs the linear move. For arc moves (G02, G03) it has to preset the cutter angle for the start of the move, then program the cutter angle to follow the changing angle of the cut move. Input file, currently X0 Y0 : G03 Y1 R0.5 Output file : G01 C0 G03 Y1 R0.5 C180 This is assuming C=0 is with the knife pointing toward +X, Positive C is counterclockwise, and that I got the arc direction right.
