What will it do?

I going to be a machine to facilitate a production prosses in a ceramic workshop, this machine is based in the movement of the CNC machine, the idea is that the machine saves the position and inject a paste ceramic inside of the mold, this proses is important because requires a constant control, the mold is made of plaster and in the contact with the paste ceramic the mold absorbs the humidity and the paste begins to decrease and need to fill it.

In this process, I have two variables number of molds and the amount of ceramic paste that each one needs and for this the machine should save the position and with a sensor control the amount of ceramic paste.

Who's done what beforehand?

I did not find the exact example but is the combination of these two processes, the first machine is known as filter press ceramic and in the second video you can see the injector to paste ceramic in the first process until the second 0:35.

What materials and components will be required?

For fluid control:

• - 1 Photoresistor (not in fab inventory).


• - 1 Laser (not in fab inventory).


• - 1 Electro valve (not in fab inventory).


• - 2 Attiny 44.


• - 1 relay (not in fab inventory).


• - Headers.


• - 1 transistor (not in fab inventory).


• - Resistances.


• - Capacitors.


• - LEDs.


• - diode.

For the machine:

• - Metal rods.


• - Square tubes.


• - For the frame, you can use different material: MDF, acrylic, 3D print, etc.


• - Washer.


• - Stepper motor.


• - Flexible coupling for stepper motor.

Where will they come from?

• - In fab inventory.


• - The others were locally.

How much will it cost?

For the components, they are not in fab inventory:

• - Photoresistor 1$.


• - Laser 9$.


• - Electro valve 3$.


• - Stepper motors 20$


• - Transistor 0.30$


• - Relay 1$


• - Iron Rods 30$


• - MDF 2,40$


• - Square tubs 23$


• - Miscellaneous expenses $25

What parts and systems will be made?

• - PCBs to control fluid.


• - Machine frame.


• - Design of guides.


• - Structure of machine.

What processes will be used?

• - Computer controlled cutting.


• - Electronic production.


• - 3D print.


• - Electronic design.


• - Embedded programing.


• - Input device.


• - Networking and communications.

What tasks do you need to complete?

• 1. Control an electro valve with a relay.


• 2. Connect the electro valve with the sensor photoresistor.


• 3. To obtain the position of the machine.


• 4. Save the position in a database.

What questions need to be answered?

• - How control the pass of paste ceramic?


• - How add a sensor to control the ceramic paste?


• - How save the position of the mold?


• - How control the machine as a CNC?

What is the schedule?

How will it be evaluated?

Make some tests, first check all the circuits made and when all the circuits are right make test with the paste ceramic and correct some errors, check fluid behavior.
