Method and apparatus for measuring geometry elements

An apparatus for measuring geometry elements, comprising:

• a measuring machine for measuring one or more sample points on a work required to calculate a geometry element which defines the work to be measured and outputting measured data;
• a sampling and sample processing section for receiving said measured data of said sample points measured by said measuring machine and counting the number of said sample points received, said sampling and sample processing section determining the finish of reception of all sample points required to calculate said geometry element when a predetermined time is elapsed after the last measured data is received;
• and
• an element discriminating section for discriminating said geometry element which defines the work to be measured on the basis of said measured data and the number of said sample points received by said sampling and sample processing section.

A method of measuring geometry elements, comprising the steps of:

• receiving one or more sample points on a work required to calculate a geometry element which defines the work to be measured and counting the number of said sample points received;
• determining a distribution of said sample points received in the step of receiving;
• and
• discriminating said geometry element to be measured on the basis of said distribution of all sample points determined in the step of determining and the number of said sample points counted in the step of receiving.
