This paper studied the relationship between the spindle fault and the roughness characteristics， by surface roughness of machining. Spindle common fault is divided into the spindle system is not balanced, the spindle system is not right, the spindle system has a transverse crack and the spindle system rolling bearing failure. The characteristic amount of the machining surface is extracted by CCD laser speckle surface roughness measurement technique. Machine fault information and rough surface

This paper adopts ordinary CCD cameras and IR filters to constitute IR cameras for a marker-based quadri-ocular tracking system. However, the IR filters will affect the accuracy of the tracking system. Therefore, this paper analyses the refraction of IR filters and finds IR filters will bring about the biggish radial distortion on imaging process. And then, this paper directly uses Zhang’s technique to calibrate the parameters of IR cameras in infrared environment by adjusting the imaging

one-factor method in optimizing conditions as it minimizes the number of chemicals used along with less labor (Asghar et al. 2014).
Central Composite Design (CCD) provides excellent predictions within the design space and has more centre points as compared to others like Box-Behnken design (BBD). Moreover, it is particularly used for studying extreme conditions or values both high and low resulting in a better quadratic design (Othman et al. 2017). Hence, the present study entails the use of

theoretical CCD acquisition time of down to 1 μs. The interferogram thus captured can be applied for further phase retrieving using the developed frequency transform and band-pass filtering strategies. The band-pass filter is designed to obtain phase information for optimizing the 3-D surface reconstruction with both dimensional and structural measurement accuracy. Furthermore, a standard step-height target was measured to analyze accuracy and repeatability of the developed methodology. Experimental
