TcnCAM

Easy CAM-Solution for CNC-machining center with Woodflash (TpaCAD) Software.
Writes tcn-files from Rhino 2D curves.

Normally this filetype is created with TPACad.

For Review and special settings, open the file in the TpaCAD software.

This programm needs 2D objects. For generating this from 3D objects,
you can use some Rhino commands:
duplicateFaceBorder

For every processing you need a separate curve

Steps
------

1. Create curves on CPlane world top
2. Set processing parameter to every curve, with command tcSetParamTrial
3. Create tcn-files with command tcMakeFileTrial

Commands
--------
tcSetParamTrial: help you to set working parameters
tcMakeFilesTrial: creates tcn-files

Layer
-----
The program interprets Layernames:
Example for milling: 
cnc-mf-sd2-tz12-tl2026-st4-br4
cnc: charakters for grouping processing layers (must be first parameter)
mf: processing modus (must be second parameter)
sd: side, 0=center, 1=left, 2=right
tz: tool z, depth
tl: tool no.
st: number of steps in z direction
br: number of bridges to fix the piece

Example drilling:
----------------
cnc-dr-tz12 = Drill 12mm deep, diameter of circle is diameter of hole

Modus
-----
co = construction (processing = off)
dr = drill
mf = mill flying in
ms = mill side in
mp = mill point in
me = mill empty
sx = saw in x
sy = saw in y
s4 = saw 45 degree

Settings
--------
tl        tool
tz        tool z value
il      inlet length
it      inlet type
ir      inlet radius
st      Steps in z
sd      correction side
br      number of bridges
bz      Bridges thickness

Trial Version
-------------
The Trial version is not for production use, because:
- points and radius of arcs have a deviation
- correction tool is off

Exception:
----------
Circle for milling: make from a circel (2 points) half circle and connect them to have at least 3 points.
