I have made a Automatic wire cutting machine using Arduino nano controller board.
Basically there are 3 process level of this machine like
1) first process is Input
Input like wire length and wire quantity provided by pressing push button also the real time data can read on 16 X 2 LCD
all the inputs were processed by arduino nano and give command to stepper motor to feed required length of wire and instruct to servo to make cut of required quantity.
Stepper motor, servo motor & cutter are the final output component
Step 1: Material Required
Followings are the material required
Arduino nano :- http://amzn.to/2Dcp2bK
Stepper motor :- http://amzn.to/2Dg6wycstepper
Motor driver :- http://amzn.to/2Dg6wycstepper
16 x 2 LCD :- http://amzn.to/2Db9LYA
Servo motor :- http://amzn.to/2r5oejj
Cutter :- http://amzn.to/2D9X6oZ
PCB terminal :- http://amzn.to/2r8uCq7
Push buttons :- http://amzn.to/2D9XbsN
Step 2: PCB Design
I have prepare PCB layout in fritzing software then Designe a PCB and export its gerber file
This gerber file uploaded to Jlcpcb.com to order the PCB as soon as you recived PCB you need to solder some female header pins to mount arduino nano, LCD display & A4988 driver also solder the PCB terminal to connect power supply to the PCB and to connect stepper motor to PCB here I attached the editable PLC layout file so if you can do any modification required.
Step 3: Procedure
So as soon as all the components are available you can start assembly the machine.
For the base of the machine I used 3MM thick white acrylic sheet
I drill some hole on sheet to mount PCB, Stepper motor with extruder set, cutter & servo motor for better idea please watch video it will give a idea how to mount those components on sheet all the components are tightly mount on the sheet now we can move to program our arduino
Step 4: Arduino Program
Upload the code to the arduino
Now connect the 12V DC at terminal of PCB this is for stepper motor and connect USB to arduino nano this will feed power to arduino itself and servo motor now machine is ready to perform you need to press those push buttons to navigate between screen and to select desire data hope you will like my this project
