Application of infrared and high-speed cameras in diagnostics of CNC milling machines – case study

The paper presents the results of application of high-speed and infrared cameras in the CNC machine diagnostics. Experimental studies were carried out using vision methods to measure the positioning of table and thermal expansion of screw realizing the feed of the milling table. The tests were conducted on machining centre HAAS MiniMill 2. Linear motion of table was recorded using the high speed camera Phantom 5.2. To determine the positioning error of work table in the function of temperature of the lead screw the infrared camera SC620 Flir was adopted. The positioning error and the maximum value of temperature the lead screw were determined.
