Q1. Different between runout and concentricity
Ans. 
Runout measures the total indicator reading (TIR) of a rotating part, while concentricity measures the center point of a feature relative to its axis.
• Runout is the total indicator reading (TIR) of a rotating part, indicating how much the part deviates from a true circle when rotated.

• Concentricity measures the center point of a feature relative to its axis, ensuring that the feature is centered around a common axis.

• Runo...read more

Q2. How to check powder coating without thickness meter
Ans. 
Use visual inspection, cross-cut test, and weight measurement to check powder coating thickness without a thickness meter.
• Perform visual inspection to check for any uneven coating or areas with no coating

• Conduct a cross-cut test by making a small incision in the coating and checking the layers

• Measure the weight of the coated object before and after coating to estimate the thickness

• Compare the appearance and weight of t

Q3. How to check roughness without roughness tester m/c
Ans. 
Use visual and tactile inspection methods to check roughness without a roughness tester machine.
• Use visual inspection to look for uneven surfaces, scratches, or irregularities

• Use tactile inspection by running your fingers over the surface to feel for roughness

• Compare the surface in question with a known standard of roughness for reference

• Use a magnifying glass to inspect the surface closely for any imperfections

Q4. UTM test of weld parts without UTM m/c
Ans. 
UTM test of weld parts without UTM machine
• Use destructive testing methods like bend test, tensile test, or hardness test to evaluate weld quality

• Visual inspection can also be used to assess weld integrity

• Ultrasonic testing can be utilized to detect flaws in the weld without UTM machine

Q5. What is the dial gauge pressure unit
Ans. 
The dial gauge pressure unit is a unit of measurement used to quantify pressure readings on a dial gauge.
• The dial gauge pressure unit is typically measured in pounds per square inch (psi)

• Other common units include bar, kilopascal (kPa), and atmospheres (atm)

• The specific unit used will depend on the type of dial gauge being used

• For example, a tire pressure gauge may display readings in psi, while a pressure cooker gauge

Q1. What is uptime in detail
Ans. 
Uptime refers to the amount of time a system or machine is operational and available for use.
• Uptime is typically measured as a percentage of total time, with 100% uptime indicating continuous operation.

• Downtime, on the other hand, refers to the time when a system is not operational due to maintenance, repairs, or failures.

• Uptime is crucial for production managers as it directly impacts productivity, efficiency, and ove...read more

Q1. How to calculate motor fl current
Ans. 
Motor full load current can be calculated using the formula: FLA = (P x 746) / (V x Eff x PF x 1.73)
• Calculate the power (P) of the motor in horsepower

• Determine the voltage (V) of the motor

• Find the efficiency (Eff) of the motor

• Identify the power factor (PF) of the motor

• Use the formula FLA = (P x 746) / (V x Eff x PF x 1.73) to calculate the full load current

Q2. What is ammeter how it is working
Ans. 
An ammeter is a device used to measure electric current flowing through a circuit.
• Ammeters are connected in series with the circuit in which the current is to be measured.

• They have a low resistance to prevent significant voltage drop in the circuit.

• Ammeters are calibrated in units of amperes (A) or milliamperes (mA).

• They typically have a needle or digital display to indicate the current reading.

• Ammeters can be analog o
