For this assignment
I want to make a desk, first I will make the drawings in 2D in
Vectorworks ,then I opene the file in RhinoCam to do
the settup of the CNC router specifying the tooling, the rpm,
the mmXs, the depth, etc then we need to send the information to
the CNC computer to set up origins, depth of material and
sacrifice bed , also we need to fix the board in the surface of
the CNC with some clamps then push play, latter, when the CNC
finished to cut all the pieces the assembly part begins, I made
this desk like a press fit kit and it include one open space at
the front to put a computer or books, 1 drawer and a superir
space to put some pens ands post its and an electrical contact.
Vectorworks,
Enrouter, CNC computer, CNC router, straight flute tooling
And the units in mm
First I start drawing a
board size rectangle of 1220x2440mm
Here in left side view
of the desk I draw some construction lines to delimit the position
of the legs
The legs where drawing
at fist with offset tool and then I mirror them
The side voiew with the
legs and starting to draw the front view
In hte left side of my
drawing there is the geeral views of the desk, then I put all the
pieces inside the OSB board rectangle
here we can see the
places where the legs support asemmble
With the clip Surface
action I remove some section of the drawing where other parts
assemble
exploded view of the
drawers components
I made one layer for
each of the components of my desk and at the end I put them all in
one single layer with a 1:1 scale
When all ready I
exported it in DXF format
Here is the archive in
Enrouter
where we are going to
setup the CNC router settings
We are going to use a
straight flute 1/4" End Mill and we are setting a 17.2 mm depth
Final step depth in
4.00mm, Speed between 700 and 3500 during the the initial sequence
of router and during the cut and rotation speed of 11000rpm
Here we simulate the
router path, the outer and inner cuts, first we must cut the
interior pieces and then the outside
The Gcode
Then we send to "jobs"
the archive so we can see it in the CNC computer control
We are going to use a
AXYZ CNC model
Here we are going to
measure and set the board thickness touching the surface of a piece
of paper with the tooling
setting the thickness
in 15.287mm
setting the origin
calling the archive to
cut
We are a few seconds
away to start cutting the desk
warming up and reaching
the RPM
The OSB board
Cutting the pieces of
the desk
detail view of
the bass relief of one of my pieces
The legs and lower
support totally assemble
A detail of one union
Detail of the crossbar
joint
The top cover with two
sections
The top cover just
about to be assemble to the top section
Both interior sections
of the desk
A free space in the
left and a drawer in the right
Two additional covers
in the top surface
A top view where we can
see a cable for charging a cellphone and the space for stationery
