摘要:
The present invention discloses a machining control apparatus capable of decreasing a machining error, comprising: a rotation velocity decision process part (71) for deciding a rotation velocity (S) of the rotation tool (5) in such a way that an amplitude of vibration of the rotation tool (5) is decreased, based on a vibration state of the rotation tool (5) and a vibration phase (θ) of the rotation tool (5) when the rotation tool (5) receives the cutting resistance force(Fy), in the case that the rotation tool (5) vibrates due to the interrupted cutting resistance force (Fy) generated in the rotation tool (5) during the interrupted cutting; and a rotation velocity control part (73) for controlling the rotation velocity(S) of the rotation tool (5) based on the rotation velocity (S) decided.
