Abstract
To provide a numerical controller that can detect a position in a machining program at which a speed control abnormality is likely to occur due to an insufficient look-ahead blocks that are used to determine an acceleration/deceleration operation, and supplement the look-ahead blocks at that position in order to stabilize feed rate, cutting speed and other factors. A numerical controller includes a required look-ahead blocks setting unit that sets a required look-ahead blocks, which is a look-ahead blocks required to execute a machining program, and an operation limitation unit that compares a look-ahead blocks calculated by a look-ahead blocks calculation unit to the required look-ahead blocks and, if the look-ahead blocks is less than the required look-ahead blocks, limits execution of the machining program until the look-ahead blocks reach the required look-ahead blocks.
