Abstract:
A control device for controlling a machine tool so as to drill a workpiece based on a machining program, includes a motor control unit configured to, when drilling the workpiece, control an axis feed motor of the machine tool so that the rotary tool of the machine tool is axially moved by intermittently decelerated feed in which the feed rate of the rotary tool is alternately switched between a first feed rate and a second feed rate that is lower than the first feed rate, under the condition in which the relational equations (1) and (5) are satisfied.

Claim (Index 1):
A control device for controlling a machine tool so as to drill a workpiece based on a machining program, wherein the machine tool includes a rotary tool configured to drill the workpiece and an axis feed motor configured to move the rotary tool in an axial direction,\n the control device comprising: a motor control unit configured to, when drilling the workpiece, control the axis feed motor so that the rotary tool is axially moved by intermittently decelerated feed in which a feed rate of the rotary tool is alternately switched between a first feed rate and a second feed rate that is lower than the first feed rate, under a condition in which the following relational equations are satisfied: F 1 \ue89e t 1 + F 2 \ue89e t 2 = F S \ue8a0 ( t 1 + t 2 ) ; and t 2 = 1 S \ue89e ( F 1 F 1 - F 2 + C ) where S is a rotational speed of the rotary tool; F S  is a feed rate specified in accordance with the machining program; F 1  is the first feed rate; F 2  is the second feed rate; t 1  is a first rate moving time for which the rotary tool is moved at the first feed rate in one switching cycle; t 2  is a second rate moving time for which the rotary tool is moved at the second feed rate in one switching cycle; C is a constant; and F 1 >F S >F 2 >0, and C\u22650.
