When a feed shaft is decelerated from the constant speed state to a stop state in a drilling operation, a bell-type acceleration/deceleration mode is selected from the constant speed state to a linear deceleration mode where deceleration is carried out at a constant rate, and then a linear deceleration mode in which a deceleration is carried out at the same constant rate as in the linear part, from the linear part to the stop state. Thus, it is possible to carry out a high-speed operation in the vicinity of a portion having a speed of zero around a hole bottom while performing a smooth deceleration."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Numerical controller for controlling drilling operation","description":"A numerical controller controls a drilling operation.
