Abstract
A machining control device according to an aspect of the present disclosure includes: a machining step extraction unit that analyzes a machining program to extract a plurality of machining steps in each of which a feed rate of a tool is changeable; a precedence setting unit that sets precedence to the machining steps extracted by the machining step extraction unit; a machining time period calculation unit that calculates a machining time period of each of the machining steps based on the machining program; and a set value changing unit that changes set values of the feed rates of the tools in descending order of the precedence set by the precedence setting unit such that a sum of the machining time periods calculated by the machining time period calculation unit approaches a target value.
