Micrometer Simulator for Android

11 things about Micrometer Simulator

1. This applet has an object (Black) with slider on left top to control the y-motion of the object into the anvil and spindle (jaws), the graphics also allows drag action.

2. The basic operating principles of a micrometer are as follows: The amount of rotation of an accurately made screw can be directly and precisely correlated to a certain amount of axial movement (and vice-versa), through the constant known as the screw's lead.

3. answer: shows the measurement d = ??? mm lock: allows simulating of the lock function in real micrometer which disable changes to the position of the spindle then by the measurement is unchangeable.

4. Lock nut / lock-ring / thimble lock (Blue) The knurled part (or lever) that one can tighten to hold the spindle stationary, such as when momentarily holding a measurement.

5. with slider on left bottom to control the x-size of the object into the anvil and spindle (jaws).

6. (In most threads [that is, in all single-start threads], lead and pitch refer to essentially the same concept.) With an appropriate lead and major diameter of the screw, a given amount of axial movement will be amplified in the resulting circumferential movement.

7. On the bottom there is a green slider to control the position of the spindle, drag on any part of the view also drags the spindle.

8. On the left bottom slider is the zero error control to allow of exploring with if the micrometer has either +0.15 mm (max) or -0.15 mm (min) zero error.

9. Spindle (Dark Green) The shiny cylindrical part that the thimble causes to move toward the anvil.

10. Anvil (Gray) The shiny part that the spindle moves toward, and that the sample rests against.
