The invention discloses a multi-axis linkage motion control method based on an embedded cutting bed controller. The multi-axis linkage motion control method comprises steps that 1) maximum acceleration and maximum non-cutter lifting rotating angle permitted by an accelerometer, a speedometer, a stepped step size meter, and a cutting bed are acquired; 2) a speed planning and acceleration/deceleration process of continuous line segments is as follows: maximum speeds, target speeds, and angles required by a C-axis of various inflection points are calculated; 3) during cutter rotating at the inflection points, when an inflection angle delta theta i is smaller than theta, a direct cutter rotating way is adopted; when the delta theta i is greater than theta, an inflection angle cutter rotating way is adopted; 4) when a cutting track is continuous small line segments, the cutter rotating at the inflection point adopts a three-axis linkage way.
