This week as just amazing from the globel classs it self i had thet understandging that we will b e doing a lot of hands on stuff this week and yes indeed we did we primerly focused on cutting 2d shapes from vinyal stikers and cardbord along with that this week we also did a groups assigmennt that helped the entire team to have fun and was a good start for the comming weeks
the first machine that us was introduced was the vinayal cutter it used a plastic vinayal shhet as the stock materil and used a thin metal knife to cut the material it was a 2 axis machine with pasive knife controlls and the make is,The machine referred to is the Roland GS24. This vinyl cutter is well-known for its precision cutting capabilities and user-friendly interface. It has been widely used in various industries for cutting vinyl sheets and other similar materials with high accuracy.
in oder to cut a test part there was a button wicth when clicked will cut a sample round with a squre inside ,the machine also fetures knife force adjustmenst xy jogging switches and orgin set button
in odrder to cut the first part i useed inkskape to convert a file from png to bitmap and then moved to the pc connected to the machine and lunced the fab nods
after lunching nods we went to programs and in programes we selected the corresponding machine that is the Roland GS24
then using the fab nods i converted the bitmap wich was saved as png the got converted to the tool path,i used the terminal to lunch the fab nod.
after that some settings was made in the machine first we loded the material that is vinayl sheet and selected wher it is a piece or sheet then the machine moved to set the limites of the sheet and one key thing to notice here is that the sheet should be loded iun bettween the white markes whre the grip rollers are, the i set the origin and accodring to the origin in the fab nods set the starting point to be bottom left and send the file from nod to the machine
then i simply pealled the sticker out of it using tweezers and i cut diffrent colors and charecters of packman it was stuck on my laptop
the i moved on to bit of a chalnging task using the copper stiker to make a warable pcb stiker i drew a simple heart shape and made it to attach a 1206 led on it
then using the fab nods send the files to the Roland vinyal cutter and set the knife cutting force to 100gf to get a clean cut, then i carefully moved to stiking it to my fevorite hoddies
then using the soldering station i solderd 2 1206 package led to the circit and connected it with the powersupply setting the voltage to be 5v volla we have light
so as our second assigmnet we ware told to build a pressfit constraction kit so before doing that we did an group assigment to find out the clerances and dimesions to achive a press fit finger joint
thn i fired up the fusion 360 enviorament and started sketing and i finalised on craeting a geodesic dome kit that can be re arannged into more shapes as well and using the paramtric design tool i gave different parameters like circle diameter,slot size.slot diameter and used it reflect it all through out the design even whlie changeing the size of the parts
i setlled with these 4 parts to be cut and imported outer sketch of the drwaing using the projcetion tool and then the dxf was imported to inkscape and i nested the parts using align and distribute tool and saveed the file to a flash drive
then moved on to understanding the laser machines in our lab but sadly they are all damaged or undermaintance yet i was able to get some grasp about the basic working of laser cutter and we used another laser from near by lab to finish the group assigments
this is the main machine that is used in our lab it is a co2 and fiber intagrated laser wich as told in the class can produce different laser wavelengsth to cut or engarave metals,wood acylic and more materials on one machine itself, i was first introduced to the basic saftey of the laser and machine then moved on to starting the machine using the key,
and then used the control pannal to jog the machine and set the autofocus fuction and also i was introduced to the software as well named trotec job control and did a cut and engarve as a part of the group project sadly the machine was damaged and wasent cutting well so i moveed on to zund cutting machine
The Zund digital cutter is like a high-tech craft machine. It uses a computer to cut out shapes from different materials like paper, fabric, or plastic with extreme accuracy. It's super precise and fast, making it perfect for industries like packaging and signage. With its easy-to-use software named cut editor and cut queue, we can create intricate designs and turn them into real products in no time.
then i loded the file to zunds computer via flash drive and loded the cut editor sodtware and setup the file setting offsets and doing design corrections
then i send the file to server and loded it on cut queue and set the tool bed offsets and send the file and brought the machine online and set the coreners using manula s well as auto mode to maximise on material used the the zund started cuuting
after that i stared assemblying the dome and i did select the dome as a remebrnce to my first startup named MAKERSDOME,onece the dome was finhisned i moved to other shapes as well like a flower holder, and a kind of a dna strcture..
then i uploded the files to my thingiverse page so anyone can try it out
