Virtual Micrometer in Hundredths Millimeter – Simulator

`Virtual micrometer in millimeter hundredths - simulator of use, reading and interpretation`

How to use, read and interpretate the linear reading instrument ‘micrometer’ in hundredths of a millimeter

measuring range 0 a 25 mm and resolution 0,01 mm

Roll until the end of the page, drag and drop the thimble of the bigger visualization in vertical to fine approximation or the thimble of the smaller visualization in the horizontal to fast avance.

Use of micrometer in millimeter centesimal (hundredths of millimeter)

Micrômetro – Micrometer – Micrómetro

The resolution of the micrometer is obtained from the interaction between the so-called ‘micrometric thread’, which is stoned in the spindle, and the thread of the ‘inner bush’. Generally, in the micrometer in millimeter, the micrometric thread is of an entrance and its step is 0.50 mm (fifty hundredths of a millimeter, five tenths of a millimeter or half millimeter). This means that a complete (360°) rotation of the drum, and of the spindle that supports it, will produce an advance equivalent to the pitch (fifty centimeters of millimeter), two full turns will produce an advance of 1.00 mm (one millimeter).

The resolution of this instrument is obtained thanks to the perimeter of the drum, where 50 equidistant divisions are minted. A complete spin of it will produce an advance of 0.50 mm and the fifty divisions will ‘sweep’ the ‘reference line’. In this way, each division of the drum ‘marks’ the advance of 0,01 mm (one hundredth of a millimeter) of the spindle. That is the resolution of this instrument.

This simulator is a replica of the metrology instrument used in the metal mechanics area. In it the value that appears in parentheses is obtained by interpolation. Human vision is not accurate enough to determine this measure.

Main components of the micrometer

Frame, sleeve, thimble, reading line, fuse, meause faces, lock nut and ratchet are some of the components of the micrometer <- to know better them click here.

Virtual micrometer: how to use the micrometer in hundredths of millimeter

• click in the eye to hide the result of the measure in mm
• to reduce the number of clics, this simulator has a fast avance
• drag and drop in the horizontal barrel of smaller view
• to fine adjustment, drag and drop the barrel of bigger view in the vertical
• the value between parentheses “()” is result of interpolation.
