1. Safety precautions
·
All specialists must study this User's Manual before operating the machine.
·
Use supply voltage and interfaces indicated in the machine specifications.
·
In connection/disconnection of cables, the power must be switched off.
·
Do not use the machine in locations close to powerful light sources.
·
To obtain stable results, wait about 20 minutes after powering the machine to
achieve the uniform warm-up of the micrometer.
·
During the measurement procedure, the protective doors of the machine must be
closed.
2. CE сompliance
The machine has been developed for use in industry and meets the requirements of
the following Directives:
·
EU directive 2014/30/EU. Electromagnetic compatibility (EMC).
·
EU directive 2011/65/EU, 'RoHS' category 9.
3. Laser safety
The machine contains an optical micrometer, which makes use of a LED. The
micrometer belongs to the 1 laser safety class. The following warning label is placed on the
housing:
The following safety measures should be taken while operating the micrometer:
·
Avoid staring into the emitter during a prolonged time period.
·
Do not disassemble the micrometer.
4. General information
The machine is designed to control the geometrical parameters of the 'shaft' type
parts.
Field of application: large-scale production. Place of installation: production line, or
laboratory.
Technical characteristics of the machine can be changed for a specific task.
5. Structure and operating principle
5.1. Optical micrometer
To measure the geometrical parameters of the 'shaft' type parts, a two-axis optical
micrometer is used.
The operating principle of the micrometer (for one axis) is illustrated in Figure 1.
The micrometer consists of two blocks: transmitter and receiver. Radiation of LED
1 is collimated by a lens 2. With an object placed in the collimated beam region, a shadow
image is formed by the telecentric system 3 on the CCD photodetector array 4. A
processor 5 calculates the diameter of the object from the position of shadow borders.
