Flatness Measurement

Easson2D supports collecting multiple measurement points on a workpiece surface with the probe and calculating the flatness of the measured surface from these points.

Flatness measurement is suitable for checking whether a workpiece surface has obvious height variations or plane deformation.

1. Select Flatness Measurement

Click:

Probe Measurement → Flatness Measurement

to enter the flatness measurement mode.

Once in this mode, you can directly use the probe to capture points on the workpiece surface to be inspected.

2. Probe Points on the Workpiece Surface

Move the probe to different positions on the measured surface and contact the workpiece to capture points sequentially.

Flatness measurement requires:

At least 4 measurement points

Each time the probe is triggered, Easson2D records the current measurement point.

To make the measurement points represent the entire measured surface well, it is recommended not to concentrate all points within the same small area, but to spread them across the whole effective measurement range.

For example, you can capture points at:

• The edges of the surface
• The middle area
• Positions prone to deformation

separately.

If the measured surface is large, you can increase the number of measurement points accordingly.

3. Complete the Measurement and Generate a Flatness Element

After capturing the required probe points, right-click in the:

image area or geometry area

to end the current point capture operation.

Easson2D calculates the flatness of the measured surface from the collected measurement points and generates the corresponding flatness element.

Basic Workflow

Flatness measurement can be summarized as:

Probe Measurement → Flatness Measurement → Move the probe over the workpiece surface and capture points → Capture at least 4 points → Right-click in the image area or geometry area → A flatness element is automatically generated

Point Capture Positions

The flatness measurement result is related to the distribution of measurement points on the surface.

If all measurement points are concentrated within a very small range, the result mainly reflects the surface condition of that local area and cannot fully represent the entire measured surface.

Therefore, for larger planes, it is recommended to expand the coverage of the measurement points.

For example, you can use:

points around the edges + points in the middle

so that the measurement points cover different areas of the measured surface.

Measurement Recommendations

For more representative flatness measurement results, it is recommended to:

• Capture at least 4 valid measurement points
• Spread the measurement points across the entire measured area
• Increase the number of captured points for larger planes
• Avoid burrs, dust, and obviously damaged positions
• Make sure all measurement points come from the same measured surface

After the measurement is completed, the generated flatness element can be used to evaluate the flatness condition of the current workpiece surface.
