VM Series Maintenance and Safety Manual 704-0212-209 Machine Maintenance 3- 45
Refer to the table below if small errors in dimensions show up occasionally.
Table 3–25. Troubleshooting: Errors in Dimensions
Environmental Conditions
Temperature and other environmental variables can cause problems that might otherwise
be attributed to the machine.
When the electrical cabinet overheats, control power is disabled and a message appears
on the screen until the cabinet temperature sensor registers a temperature drop to an
acceptable level. If this error condition occurs, make certain the cabinet is not subject to
an additional heat source, such as a space heater or bright sunlight from a nearby
window.
Table 3–26. Troubleshooting: Environmental Factors
Cause Solution
Temperature fluctuates as the
part is machined.
Stabilize the temperature of the blank by providing
enough coolant while machining.
Problems Causes Solutions
Relatively small
dimensional
problems occur
in the product.
Metal blanks stored in
temperatures much higher or
lower than the temperature
of the machining area can
expand or contract during
and after machining.
Before machining, move the blanks to
the machine area and allow the blanks
time to reach ambient temperature.
Dust, debris,
rust or
discoloration
accumulates on
work surfaces.
Extreme temperatures are
typically the problem, and/or
the environment is too humid
or too dusty.
Improve the machine environment. For
example, close the machining area to
outside dust and install air conditioning
to lower room temperature and
humidity levels.
