Assignment
No. 3 Computer-controlled cutting
Objectives: Group assignment: Characterize your lasercutter's focus, power, speed, rate, kerf and joint clearance Individual assignment: Cut something on the vinylcutter Design, lasercut, and document a parametric construction kit, accounting for the lasercutter kerf which can be assembled in multiple ways and for extra credit include elements that aren't flat GROUP ASSIGNMENT -COMPUTER CONTROLLED CUTTING-: We must test court to start knowing the different speeds and powers with which podran the materials to cut, any that these are, we begin for developing a small format in AutoCAD, in which small pictures have been distributed in order that with them juquemos with the powers and speeds of the machine, for our case we use a LaserPro of GCC, model Spirit GLS of 80 watts of power: The ideal valors for MDF or cardboard are: Cut MDF: Power 90 % Velocity 1.4 % Cut cardboard Power 90 % Velocity 4.4 % For this task, we must use the equipments laser and court of vinil. We will have to design an object which we will have to develop to be able to cut it with laser, with RhinoCeros I give him form to the structure with which I want to divide, only I show the end of the design draw:
Export file with Stereolithographer Since to be able to continue with the exercise it will use a program that is called itself Autodesk's MERGER SLICER FOR, it is of free access and very easily to use. I import the figure and measure her, want it of 300 mm of high place
Since to be able to continue with the exercise it will use a program that is called itself Autodesk's MERGER SLICER FOR, it is of free access and very easily to use I import the figure and measure her, want it of 300 mm of high place
I select the technology of construction, for my case it is A Radial Slices
With this program I can increase or diminish the quantity of axes
Here my final design is
Here my final design is
Slicer is a program very easy to use, with I can parametrize if I need to increase the size and / or the thickness of material, for example, increases the size to 600 mm and the thickness of material to 6 mm, obtaining the following thing:
Returning to the file DXF to cut from Autocad, I it have annexed to a box of 90 x 60 cm, which it corresponds to the area of work of the laser with which it will cut
There will use acrylic crystal of 1.5 mm of thickness
With two different colors of lines, white to record and red to cut, I programme the machine with 70 % of speed and 60 % of power to record and 3 % of speed and 85 % of power to cut; correspondents to a Spirit LaserPro's GLS, it arrives already described.

My finished pieces, acrylic crystal of 1.5 mm of thickness
Assembling my structure
Finished piece:
VINYL CUTTING The plotter of court uses also of vinil and as also from Rhinoceros and CoreDRAW cuts it: Draw It in RHINO
Spend it to CorelDraw, to be able to turn PLT, which is with that the plotter of court works of vinil. Though I could have drawn it directly from CorelDraw to spend it to the plotter.
The plotter of court of vinil of GCC, is a model PUMAIII of 132 cm GCC's
In Great cut, it is the software of the equipment
It is cut by a pressure of 80 gr, speed of 30 cm/seg
