<p>PURPOSE:To improve the operational efficiency of a numerical control system by performing the pseudo control of the NC data in a lower rank control means by a higher rank control means and automatically deleting unnecessary NC data in this lower rank control means. CONSTITUTION:A matching processing means 4 judges additional NC data which is necessary to be supplied to a lower rank control means and unnecessary NC data which becomes unnecessary in the NC data that this lower rank control means 1 holds. A higher rank control means 3 supplies the additional NC data and the index information on unnecessary NC data that the matching processing means 4 judged to a lower rank control means 1. The lower rank control means 1 adds/holds these additional NC data and deletes unnecessary NC data based on these index information. Namely, a pseudo control is performed for the NC data in the higher rank control means 3 and the lower rank control means 1, the supply of NC data to this lower rank control means 1 is minimized and the deletion of unnecessary NC data in this lower rank control means 1 is automated.</p> |
