Therefore the way of dial micrometer works is notably different from the mechanical micrometer. Rotate the ratchet stop until the spindle contacts the item.

Reading A Micrometer Engineering Tools Measurement Tools Mechanical Engineering

Use either a clean sheet of paper or soft cloth and hold it between the anvil and the spindle.

How to use a micrometer. Product demo video showing how to read a Mitutoyo micrometer. Slowly pull out the sheet or the cloth1 X Research source This practice isnt a necessary step for measuring but keeping. A dial micrometer utilizes dial gauge to display the measurement reading.

The proper way to use a micrometer is to hold it in your dominant hand. In a micrometer the object you wish to measure is clamped between the anvil the stationary end of the clamp and the spindle the moving part of the clamp. These are the whole millimeters.

Move the ball around the measuring faces and see how the zeroed measurement changes. On one side using a micrometer by handheld is simple compact and quick on the other hand it increases measurement inaccuracy because your hand is directly contacting the micrometer so that lets the heat from your body transfer easily. I also point out some of the pitfalls and common mistakes that Ive noticed time and time.

Mitutoyo product demo video showing how to use a digital micrometer. Having that said do not use a mechanical screw micrometer to measure paper thickness. Make sure the micrometer is perpendicular to the surfaces being measured.

The correct method to hold the micrometer with your hands. Set zero with the sphere in the center of the anvil faces and zero. Describes how to hold measure and read a micrometer.

Use a small sphere or the stylus of a digital probe. If there is an additional line uncovered on the top row this is equal to one-half a millimeter Figure 3. Slightly place the item to be measured against the anvil of the digital micrometer.

Finally partially wrap your pinky or ring finger within the inside of the frame. Although your micrometer is digital avoid the digital that can be converted into manual mode. With your right hand using your pinky finger and the finger next to it grip the frame with the front of the micrometer facing you.

The above image shows a typical micrometer screw gauge and how to read it. For proper micrometer handling hold the middle of the body in the left hand and the cuff or ratchet in the right hand keep the hand out of the edge of the anvil. Grasp the thimble between your thumb and index fingers.

Heres a how-to video on reading both Inch and Metric micrometers. So the first part. This video shows the steps required to read a standard micrometer or vernier micrometerSubscri.

Step 1 Familiarize yourself with the anatomy of a micrometer. Notice that there is an extra line below the datum line this represents an additional 05 mm. The micrometer is available in various sizes and ranges and the corresponding micrometer should be selected depending upon the size of the workpiece.

Place the C-shape of the frame against your palm. To obtain the first part of the measurement. Dial micrometer is an important tool that can be used to measure brake rotor warpage precision engine building deck clearances and to measure the distance between two surfaces.

So 05 mm would need to be added to the measurement. Hold the Micrometer Properly The position of your fingers is illustrated by the image above. That kind of micrometer commonly has the spindle that rotates when it moves to hold the object going to be measured.

Gently twist and close on the sheet or cloth. This grip allows you to hold the micrometer upright and enables you to spin the spindle using your pointer finger and thumb. Look at the image above you will see a number 5 to the immediate left of the thimble.

Carefully open the jaws of the digital outside micrometer by revolving the ratchet. It must stay within the micrometers tolerance. Ratchet stop Thimble Frame Thimble lock Spindle Anvil SleeveStep 2 Clean the anvil and spindle before beginning.

Micrometer should be cleaned of any dust and spindle should move freely. Some parts are stationary while others are movable. Once the object is secured in the clamp you use the numbering system on the thimble the handle portion to find your measurement.

Check and set the zero reading before measuring. This means 50 mm. To read the metric micrometer first read the number of whole millimeters on the bottom row of the sleeve of the micrometer Figure 3.
