Title:
PROCESSING SYSTEM, DISPLAY SYSTEM, PROCESSING DEVICE, PROCESSING METHOD, AND PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/123731
Kind Code:
A1
Abstract:
This processing system comprises: a cutting tool; a sensor mounted on the cutting tool; an analog to digital (AD) converter which samples an analog signal output from the sensor and generates a digital signal; and a processing unit, wherein, on the basis of the revolutions per minutes (rpm) of a rotating body rotating about a rotation axis, an upper limit period that is an upper limit value of a processing period that is a period in which a prescribed process is performed by using the digital signal generated by the AD converter, and an upper limit pitch that is an upper limit value of an angle pitch [degree] that is a rotation angle between two adjacent sampling time points in coordinates that represent phases at the sampling time points from the AD converter in a rotation disc that is a trajectory of a point rotating around the rotation axis as the rotating body rotates, the processing unit determines a sampling frequency and a processing period so that the AD converter performs the sampling so that a setting value of the angle pitch is equal to or less than the upper limit pitch in a period required for a rotating body to rotate N times in a processing period equal to or smaller than an upper limit period, and when the setting value is set to ps, N and (360/ps) are integers of 2 or greater and mutually primes.
