FORM TURNING - Practice Mode
3) Calculate the length of metal passing by cutting tool in one revolution if the diameter of work is 75mm and cutting speed is 120m/min.
Explanation:
Sure, to find the diameter of the circle with a circumference of 31.4 cm, we can use the formula d = 2r, where r is the radius of the circle, and substitute the value of r using the formula for the circumference of a circle C = 2πr,
First we calculate radius: r = 31.4 / (2π) = 31.4 / (2*3.14) = 5.00 cm
Now we can use the diameter formula: d = 2r = 2 * 5.00 = 10.00 cm
So the diameter of the circle with a circumference of 31.4 cm is 10.00 cm.
4) Find out the R.P.M of spindle for a 50mm bar (D) and cutting speed is 25m/min.
Explanation:
Generator is a device that converts mechanical energy into electrical power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks
5) Which type of jig locates the piece part from its face?
Explanation:
The SI unit of electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. The ampere (symbol: A) is an SI base unit Electric current is measured using a device called an ammeter.
