"GROOVY" is a computer program for
toolcut visualization, intended to be part of a larger CAD or CNC
For contact information, see below.
The input files contain simple commands defining the toolpath for an overhead router. These commands are as follows:
|B - defines the dimensions of the workpiece;||T - describes the shape of the cutter;|
|C - change tools;||M - motion ABOVE the workpiece (z<0);|
|L - straight line motion to the new location in the workpiece(z>0).|
To illustrate, the first few lines of each (encrypted) input file (*.drf=Demo Routing File) are displayed on execution.
Presently, the following tool profiles are modelled:
1. tapered sides: flat bottom, round bottom, point (V-bit),
double-taper to a point.
2. straight sides: flat bottom (endmill), round bottom.
self-extracting zipfile - create a directory and execute: groovy_demo.exe
delete the directory created during installation
execute the following command: groovy fname.drf
choosing *.drf from the examples provided (see below), or RUN the file GROOVY.EXE and use the file selection dialogue.
Windows 9x/NT etc.; Pentium and 64 MB (128 recommended); 16-bit colour or higher
Toolbar icons are provided. From the left:
the first 6 icons control animation;
the next icon selects 3D or wireframe simulation;
the next 4 icons control magnification;
the next 2 icons control graphics output;
the next icon controls graphics preferences;
the next icon controls viewpoint;
the rightmost icon gives program information.
The graphics preferences dialogue permits colour, lighting and texture (*.bmp) choices.
Press "SAVE" button to save or "DEFAULT" button to restore preferences (GROOVY.INI).
The following sample files are provided:
hello.drf - simple cut with a V-bit (700 grooves);
atom.drf - complicated toolpaths (~17 000 grooves);
3dface.drf - photoengraving of a bitmap (~89 000 grooves).
bada.drf - incorrect choice of cutter size, interesting animation
starfill.drf - route a star with two tools; interesting magnification, especially when animated.
THIS PROGRAM CAN BE CUSTOMIZED TO YOUR SPECIFICATIONS.
