Document Type and Number:

Japanese Patent JPS6367608

Kind Code:

A

Abstract:

PURPOSE:To omit transfer of plural block data and to obtain a working form as prescribed by producing the reference linear interpolation data on a signal block to be applied to a main interpolation computing element, plural interpolation data corresponding to the commands of plural block data, and the interpolation area data and setting previously those data at each set value. CONSTITUTION:Plural interpolation data and interpolation area data are produced and set previously to the interpolation area setting device 4-7 and to the interpolation data setting device 12-15 respectively. A main interpolation computing element 1 performs the interpolation arithmetic for each synchronizing signal S1 received from a spindle and delivers the distribution data S3. An integrator 3 delivers the integration value S4 and 1st-4th comparators 8-11 compare the value S4 with set data S5-S8 given from devices 4-7 respectively and deliver the comparison results S9-S12. A discriminator 16 selects one of those devices 12-15 based on the comparison results given from comparators 8-11 and delivers it to a secondary computing element 17. The element 17 delivers the distribution data S13. An adder 18 adds both distribution data S3 and S13 to deliver them in the form of the distribution S19.
