    FADAL MACHINING CENTERS 5.2 THERMAL EXPANSION Thermal expansion is a natural occurrence in materials subject to heat, and there are 5.2.1 OVERVIEW several sources of heat in any machining operation. In addition, different materials react to heat at different rates, and different subsystems of the VMC react to specific machining operations to different degrees, further complicating matters.

  • Page 89: Heat Sources

    SIEMENS MAINTENANCE MANUAL It comes as no surprise that the primary source of heat in machining is friction; however, 5.2.5 HEAT SOURCES some of the sources of friction, and all of the areas affected by a given friction source, may not be readily apparent. Additionally, the effects on the ambient temperature from various heat sources in the machine shop are often overlooked.

Yet another practice that deserves mentioning is machining parts at temperatures significantly different from those at which the parts are inspected. If the inherent expansion of the part material from the heat of the machining process is outside tolerance once the part has cooled to inspection temperatures, the problem can only be resolved by correcting for the heat generated during machining so as to keep the part...

This applies both to parts stock, like aluminum, and to fixtures and sub plates, often also made of a material like aluminum.

It will expand, but it takes longer to heat or cool the entire table. In addition, the use of coolant tends to stabilize the temperature of the table at or close to coolant temperature.

    SIEMENS MAINTENANCE MANUAL 5.4 SOLVING THE THERMAL EXPANSION PROBLEM A simplified description of the thermal environment in machining would state that heat 5.4.1 GENERAL CON- SIDERATIONS is generated through friction, and also input through ambient factors. That heat is transferred among the system components, and is either removed from the system through radiation, convection and evaporation, or absorbed by the components of the system (part, fixture, VMC).

    SIEMENS MAINTENANCE MANUAL 5.6 VMC MAINTENANCE The fans in the cabinets must be functioning properly. The purpose of the fans in the 5.6.1 CABINET FANS cabinets is to cool the electronics and to move the heat out the vents. An excessive amount of heat in the cabinets, from clogged holes or nonfunctional fans, will transfer to the column and cause it to expand, as well as damaging the electronics.
  • Page 96 FADAL MACHINING CENTERS This process is also effective for inspecting parts. By cooling the part prior to the finish cuts, the temperatures at final cut and at inspection can be brought closer. In this situation, the target temperature should also be close to the temperature at which the gauge is calibrated.

    FADAL MACHINING CENTERS Thermal expansion is a natural occurrence in any machining operation, and, when 5.6.5 CONCLUSION ignored, can significantly impact positioning repeatability. By identifying and eliminating unwanted heat sources, by calculating or measuring expansion effects and altering positioning accordingly, by performing regular maintenance on the VMC, and by adopting the machining practices outlined above, the effects of thermal expansion can be reduced.
