A method for estimating one or more process forces associated with a tool center point of a machine tool

A method for estimating one or more process forces associated with a tool center point of a machine tool, wherein the machine tool is capable of performing a machining operation in accordance with a predefined path, the method comprising:

• a. determining a first set of axis torques along the one or more axes of the machine tool based on a first machining run of the machine tool in accordance with the predefined path without performing the machining operation;
• b. measuring a second set of axis torques along the one or more axes of the machine tool during a second machining run, wherein the machine tool is performing the machining operation on a work piece during the second machining run;
• and
• c. determining the one or more forces associated with the tool center point of the machine tool based on the determined first set of axis torques and the measured second set of axis torques.

A control device for estimating one or more process forces associated with a tool center point of a machine tool in an industrial facility, wherein the machine tool is capable of performing a machining operation in accordance with a predefined path, the control device comprising:

• a. a network interface for receiving and transmitting data to one or more devices in the industrial facility;
• b. one or more processors connected to a memory module, the one or more processors configured to:
• i. determine a first set of axis torques along the one or more axes of the machine tool based on one of a model associated with the machine tool and a first machining run of machine tool in accordance with the predefined path without performing the machining operation;
• ii. measure a second set of axis torques along the one or more axes of the machine tool during machining;
• and
• iii. determine the one or more process forces associated with the tool center point of the machine tool based on the determined first set of axis torques and the measured second set of axis torques.

A non-transitory storage medium for estimating one or more process forces associated with a tool center point of a machine tool in an industrial facility, wherein the machine tool is capable of performing a machining operation in accordance with a predefined path, the non-transitory storage medium comprising a plurality of instructions, which when executed on one or more processors, cause the one or more processors to:

• a. determine a first set of axis torques along the one or more axes of the machine tool based on one of a model associated with the machine tool and a first machining run of the machine tool in accordance with the predefined path without performing the machining operation;
• b. measure a second set of axis torques in along the one or more axes of the machine tool during machining;
• and
• c. determine the one or more process forces associated with the tool center point of the machine tool based on the determined first set of axis torques and the measured second set of axis torques.
