How the Automatic Wire Cutter And Stripper Machine works
- The mild steel frame and fabrication forms the base that carries every other part, so it is designed first from the load and size of the machine.
- The Stepper motor with driver moves in precise steps for accurate positioning.
- The Pneumatic cylinder converts compressed air into linear push-pull motion.
- Motion is transmitted through pulleys and V-belt, which set the speed, torque and direction at the working end.
- The 4×4 matrix keypad lets the user enter a PIN, amount or settings.

Mechanical viva questions on this project
What is the aim of the Automatic Wire Cutter And Stripper Machine project?
A machine that cuts wires to length and strips their ends automatically. The user enters the length and quantity on a keypad, rollers feed the wire from a spool, and a cutter-stripper tool cuts and strips each piece.
Explain the working of your project in short.
The mild steel frame and fabrication forms the base that carries every other part, so it is designed first from the load and size of the machine. The Stepper motor with driver moves in precise steps for accurate positioning. The Pneumatic cylinder converts compressed air into linear push-pull motion. Motion is transmitted through pulleys and V-belt, which set the speed, torque and direction at the working end.
How does the controller read a matrix keypad?
It drives one row LOW at a time and reads the columns. A key press connects a row to a column, so the row-column pair identifies the key with only 8 pins for 16 keys.
Why is a stepper motor used for positioning?
It moves a fixed angle per pulse (1.8° for NEMA17), so the controller knows the position by counting steps without a feedback sensor.
Why is an I2C adapter used with the LCD?
It reduces the wiring from about 10 pins to 2 (SDA and SCL), leaving more controller pins free for sensors.
Why is a resistor connected in series with an LED?
It limits the current to a safe value (about 10–20 mA). Without it, the LED would draw too much current and burn out. R = (supply voltage − LED voltage) ÷ current.
What is the velocity ratio of a belt drive?
N1 × D1 = N2 × D2, so the speed ratio is the inverse of the pulley diameter ratio (ignoring slip).
Which material did you select for the main parts and why?
Mild steel (MS) is used for the frame because it is strong, cheap, easy to cut and weld and available everywhere. Shafts are made of EN8 or bright mild steel for strength, and parts that do not carry load can be aluminium or acrylic to reduce weight.
What factor of safety did you take in your design?
A factor of safety of 2 to 3 is taken for static parts and 3 to 5 for parts under shock or fatigue loading. Allowable stress = yield strength ÷ factor of safety, and each part is checked against it.
How did you estimate the cost of the project?
The cost is the sum of raw material, bought-out parts, machining or fabrication and overheads. Our estimate for this model is about ₹8,000 to ₹11,700, depending on size, material and the workshop rates in your city.
Which manufacturing processes were used?
Cutting and grinding of sections, arc or MIG welding of the frame, drilling for mounting holes, turning of the shafts and fitting of bearings and the drive, followed by assembly, alignment and painting.
Is your system open-loop or closed-loop?
Mainly open-loop: the controller runs the actuators for a set time or number of steps. Adding a sensor for feedback would make it closed-loop and more accurate.
