Machining control system

A machining control system, comprising:

• a machining data base for storing information necessary for determining initial machining conditions, wherein the initial machining conditions include at least one of feed rate and feed pattern;
• machining information determining means for producing the initial machining conditions based on the information stored in said machining data base and in accordance with adaptive control characteristics defined by adaptive control modes and adaptive control parameters;
• and
• adaptive control means for controlling machining by changing machining conditions during machining in accordance with machining states observed during the machining with the initial machining conditions as initial values of the machining conditions, wherein the machining information determining means produces different initial machining conditions when the adaptive control characteristics are in an OFF state than when the adaptive control characteristics are in an ON state, so that machining load is decreased.
