Brass tool - Measurements Report  


General

  1. The following report describes the results obtained in measuring a Brass sample (see figure 1).
  2. The objective was to measure the features on the brass with 0.01mm accuracy.
  3. We measured the sample with CP10 and 50mm lens using our demo unite (see figure 2).
  4. We used Optimet viewer for analysis.


Customer requirement

  1. Measure the height and the profile of a tool for making metal washers with accuracy of 0.01mm.
  2. To make a profile and show the tooth height.

Test Set Up

  1. The sample was put on Demo unit.
  2. The scans were performed using a CP-10 with 50mm lens.
  3. The analysis was done in using Optimet’s viewer program.

Sensor parameters:
  • Type: ConoPoint-10
  • Lens: 50mm
  • Other elements: No

Main sensor specifications:

Lens type50mm

Standoff (mm)44
Accuracy (µm)6

Scanning parameters:
  • Lateral resolution [X*Y]: 20μm X 100μm
  • Scanning axis: X axis
  • Measurement frequency: 9000Hz
  • Laser power: max (4000)
  • Auto exposure: on

Scanner system:
  • Demo unit

Measurement analysis

  1. We have scanned the whole surface and not only one profile in order to see all types of features on the sample

  2. When making a profile in the X direction


  3. When zooming in, we can see the small feastures that are in the center of the brass sample:

  4. Focusing onto the tooth hieghts we see the following:

Results

  1. Requirements:
    1. Measure brass samples with accuracy of <10um – Accomplished.
      1. Tooth height 0.5mm – I double checked it all the tooth height is ~0.151mm with STD of 0.004mm.
  2. It seems that the CP10 with 50mm lens can easily fit into this application.
