- README, lang.l, lang.y: renamed the "tool" command to "offset" - README: documented "offset" - ops.h, ops.c (tool_comp_paths), cameo.c (main), lang.y: added parameter to tool_comp_paths to treat all paths as internal - lang.l, lang.y: added option "inside" to the "offset" command - lang.y: "offset" can now take multiple options in any order

CAM Engineering and Operation
|
|
=============================
|
|
|
|
Cameo is a collection of CAM tools that convert between various file
|
|
formats and adapt the toolpath.
|
|
|
|
This is a work in progress. The plan is to integrate all the utilities
|
|
currently floating around in
|
|
http://svn.openmoko.org/developers/werner/cncmap/
|
|
into a single program and to better share common functionality.

Toolpath adaptation language
|
|
----------------------------
|
|
|
|
Loading paths:
|
|
|
|
gerber <diameter> [<filename>]
|
|
gnuplot <diameter> [<filename>]
|
|
clear
|
|
|
|
"gerber" and "gnuplot" each add paths from a file to the list of paths
|
|
already loaded. "clear" removes all paths.
|
|
|
|
If the a file name is omitted, standard input is read. The diameter is
|
|
the default tool diameter.
|
|
|
|
Note that "clear" preserves the translation set with "align", "array",
|
|
and "translate". This way, multiple files can be processed with the same
|
|
translation.
|
|
|
|
|
|
File output:
|
|
|
|
write [<filename>]
|
|
|
|
Writes all loaded paths in gnuplot format to the specified file. If the
|
|
file name is omitted, "write" writes to standard output.
|
|
|
|
|
|
Units:
|
|
|
|
mm
|
|
mil
|
|
<number>mm
|
|
<number>mil
|
|
|
|
The words "mm" and "mil" set the input to the specified unit. The
|
|
default unit is millimeter. If a number is followed by "mm" or "mil"
|
|
without intervening space, the unit is overridden for this number,
|
|
without affecting the default input unit.
|
|
|
|
Note that "mm" and "mil" only affect dimensions in the command file
|
|
and have no effect on the interpretation of toolpath files.
|
|
|
|
|
|
Horizontal adjustments:
|
|
|
|
align <ref> <x> <y>
|
|
align <ref> <x0> <y0> <x1> <y1>
|
|
array <x-step> <y-step> <x-index> <y-index>
|
|
translate <x> <y>
|
|
reset
|
|
|
|
"translate" shifts the currently loaded paths by the specified distance.
|
|
"align" is a more sophisticated form of "translate", which moves a
|
|
reference point in the bounding box of the currently loaded paths either
|
|
to a specified location (if used with three arguments) or to the
|
|
respective point in a rectangle (if used with five arguments).
|
|
|
|
The reference point is specified with a number as follows:
|
|
|
|
7-----8-----9
|
|
| |
|
|
4 5 6
|
|
| |
|
|
1-----2-----3
|
|
|
|
"1" is the lower left corner, "5" is the center, and so on.
|
|
|
|
"array" is used when cutting several copies of the same piece. The first
|
|
two arguments define the step between pieces while the second two
|
|
arguments define how many steps in each direction are taken.
|
|
|
|
"align" sets moves the toolpath to an absolute position while "array" and
|
|
"translate" move relative to the current position. The total translation
|
|
is remembered also across "clean", so that an alignment can be applied to
|
|
multiple toolpaths.
|
|
|
|
"reset" sets the translation to zero. The way "reset" is currently
|
|
implemented, it does not affect the currently loaded toolpath. (But it's
|
|
better to use it only with "clean".)
|
|
|
|
|
|
Vertical adjustment:
|
|
|
|
z [<z0>] <z0-pos>
|
|
|
|
|
|
Tool compensation:
|
|
|
|
offset [dog] [inside]
|
|
|
|
"offset" offsets the toolpaths by the tool radius. By default, it offsets
|
|
the outermost toolpath to the outside and all other toolpaths to the
|
|
inside. This can be overridden with the #%outside directive in a gnuplot
|
|
file or the "inside" option to "offset". "inside" has precedence over
|
|
"#%outside".
|
|
|
|
Concave corners on an outside path are normally cut such that the corner
|
|
is round, leaving material at and near the corner point. The option "dog"
|
|
changes this to cutting a "dogbone" hole such that material is also
|
|
removed up to the corner point.
