For turbines, creep can cause the blades to elongate, which can ultimately lead to the blade beginning to damage or pierce the turbine casing. Creep is typically measured in units of millionths-of-an-inch per hour, and a standard TF33 engine turbine operating at an exhaust gas temperature (EGT) of 555 degrees Celsius and 100 percent RPM can experience at least 50 units of creep per hour.

As turbine blades represent a non-uniform shape traditional processes involve encapsulating them in a soft alloy, making them easier to hold during grinding operations. As encasing turbine blades is a separate, time consuming process that has to be managed, ANCA engineers designed an ingenious fixture for securely holding turbine blades, allowing automatic loading.

A turbine blade is the individual component which makes up the turbine section of a gas turbine or steam turbine.The blades are responsible for extracting energy from the high temperature, high pressure gas produced by the combustor. Blades of wind turbines and water turbines are designed to operate in different conditions, which typically involve lower rotational speeds and temperatures.
