Week3

Computer Control Cutting


Group Assignment:

characterize your lasercutter's focus, power, speed, rate, kerf, joint clearance and types


Laser Cutter Procedures:


According to the directions, the cutting line strokes were set to 0.001 inches. The other vectors, however, are set to engrave with respect to their greyscale hue for 0.001 cm. Then, in the paper properties, we set the page size to 32x20 inches and the rasterization resolution to 600 dpi to convert our SVG file to PDF.

From this group assignment we learn that after all process and operation laser cutting machine is based on 2 things laser power and speed. We have to set the exact ratio of power and speed for engrave and cut which is based on material thickness and material type. More power with slow speed can burn the material and fast speed with low power can engrave but it maybe lighter enough to do job again.

KERF TEST


Kerf is the width/thickness of a cut made by the cutting tool as it cuts through different material such as wood, cardboard, acrylic, etc. The material removed during cutting. It is important to know the kerf so that the pointer of the cutting process (laser, water jet, etc.) can be slightly offset to allow for it.

The result of the 22mm box is 21.61. In this case, the kerf error is equal to 0.41.

Measurement of the inner side box, with an error of 0.97.

The thickness should be defined when designing the file to be laser cut.

Individual Assignment:

1) Cut something on the vinylcutter design and lasercut.

2) 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


First,I go through the week3 of previous student arcive and then I start my work from solid work software.I have learned solid work software from the help of youtube tutorials and ask some problems from my local instructor beacuse I did not idea about this software so in the start I have face too many problems to learn this software but I have learned too many commands from this software. When I start the work at this software so I had bored from this software but when I focus this software then I get interest from this software and I have known that is a amazing software.


Simply Easy Learning

1) I was learning software from "CAD CAM" youtube channel. I have learned to give the value of a part in a form of global variable and to make equations b/w these parts


Simply Easy Learning

In this image i was trying to make a wood slot for construction kit and press fit diagram that is a hanging lamp

I was making a second part of my construction kit that is circle diagram from the help of global variable equation.
Simply Easy Learning

I have compeleted second part of construction kit that is circle diagram.
Simply Easy Learning

first,I learned about the parametric equations and then I was giving the global values of my construction kit to make equations.


Simply Easy Learning

I was making link b/w the parts of hanging lamp.

in this picture, I show my lamp was assembled from the help of equations.

Final Result:


Simply Easy Learning

All of these parts are seen in this image after I sent the file to the laser cutter.


Simply Easy Learning

After that I have merge the all parts.

VINYL CUTTING:

Machine use:

  • Roland vinyl cutter.

    • Simply Easy Learning

    Software use:

  • Cut studio
  • Ink scape

    • First, I draw a logo for my fablab Khairpur using the inkscape software.

    Cut Studio:


    I first dragged the image onto the cut studio software and adjusted the scale because when I dragged the image onto the cut studio software, it displayed as a very large image then remove contour lines by right-clicking on the image, going to the image outline, and selecting extract contour line.
