Evaluation of Your Assignment for Computer_Controlled Cutting Week
Hi Tatiana,
It has been a long time since you have had 'Computer_Controlled Cutting Week'. Since you have not asked me yet to check your documentation, I created this issue as a gentle reminder.
Please write a message under this issue when your documentation is ready for the local evaluation.
BR,
Behnaz
Group Assignment
Please write a few sentences in your own words about the group work and what you learned.
Vinyl Cutting
Typo: "The image for vynil cuttin I prepared using Inkscape." >> vinyl cuttingTypo: "bears, spruces and vodka." >> I was not sure whether the strike through vodka is by purpose or not.Good explanation of preparing your design :)According to Fig 3, I believe you had chosen 'edge' not 'piece'. When you choose edge, only the cuttable width will be measured; While by choosing 'piece', both the cuttable width and length will appear on the display. Please modify this section and explain when you chose 'edge' then what was measured and displayed.Beautiful t-shirt :)
Parametric Design
Typo: "different sized leafes to be attached" >> leaves; (Same typo in other sentences)Typo: "that I could have use "hole" parameters" >> usedYour chandelier is beautiful in my opinion :)You need to document all the phases of your design (the design which is the main one for this assignment; the second kit) from the beginning. Currently, you have only documented the parameters and the circular pattern steps for the chandelier for example.In your second kit, where you have introduced the parameters: you have defined slot_width = 3 mm - kerf; While it should be defined as "mat_thickness - kerf". In this way, when you change the value for mat_thickness and for kerf, the value of the slot_width will also changes accordingly and therefore the size for all of the slots in your design will change. Otherwise, following your current formula, when you want to cut the same design using another material with a different thickness, you have to manually replace all the 3 mm values for material thickness in your design with the new value. The ideas of parametric design is to formulate in a way that when you change values for different parameters (in this case, material thickness and kerf), then the sizes of different parts change accordingly (in this case, slot width). So you need to: Modify the parameter slot_width based on my explanation; Replace the current screenshot of the parameters with the new one after the fixation; Explain your parameters in the text as well (pictures/screenshots are not enough). Or, you can keep the current version, explain the issue and add the new version. In any case, as I mentioned above, explanation of the design steps including the tools used for each step should be added.After Fixation, please upload .f3d file of this kit; because it should be checked.
Laser Cutting
You need to explain in detail how you worked with the laser cutter (safety instructions, jog, origin, focus, job). Since you have worked with two laser cutters, explaining the steps for only one of them would be enough.

Typo: the design parts cutted with a laser >> cut -
Lines beyond 0.02 mm will be engraved, while line widths less than 0.02 mm will be processed as “cutting”.The line width of 0.02 mm for cutting through is not a general rule. This is a value that we use in our Fab Lab for vector cutting. Moreover, still some values very close to 0.02 mm still lead to cutting through not engraving. So, please rephrase your sentence.

Since you have completed the design steps for chandelier, also add .f3d and .stl files for chandelier. -
Typo: the tep of the calibrator should slightly touch the surface of the material >> tip -
For your information: There are some slots in your second kit which do not change size when the values for thickness and kerf parameters are changed. Which is OK for this assignment because you already have objects in that design which are fully parametric and you also have the parametric design for chandelier. Anyhow, you could fix it if you find time.
