What is the feed rate for cutting double lead threads?
Your feed rate depends on the pitch of the thread i.e. 16 TPI =a feed rate of .0625
To cut a double lead thread you need to either rotate the part 180 deg. for the
second thread or change the start point by pitch /2
1/16=.0625 .0625/2= .0312 so your second thread will start .0312 from the first thread.

If facing a flange pipe on a lathe what is the circumference?
Circumference is the distance around a circle (closed curve) which in this case would be the flange's circumference. A circumference is calculated by using the mathematical constant of Pi (3.143). It entails multiplying the outside diameter by 3.143.
Example: Diameter = 145mm
145 multiplied by 3.143 equals 455.735mm

A CNC lathe and milling machine tool holder is a mechatronic device. Why?
Cause CNC tool holder is mechanical system, driven by electric motor(electronics), which is controlled by computer (software). So here you got mechanical engineering, electronic engineering and computer engineering.-also, when the machine is running your program, a tool change call enacts a bulletproof series of events. When a toolchange is executed, the process is usually very swift and precise. It must be mechatronic for that reason as well.
What is the difference between wood lathe machine and wood lathe duplicator?

What does changing the gears on the center lathe do?
Changing the gears on a lathe enables it to cut certain pitches of threads.
All turret lathes have rods. These rods are called feed rods and their purpose is to transfer mechanical power from the main drive and gearbox of the lathe to the apron attached to the saddle. This enables automatic movement of the saddle enabling unassisted cutting of a workpiece once the feed is engaged.
