PURPOSE:To enable high accurate machining without forming round at an edge part by automatically adding an automatic deceleration command cord to a first interpolation command constituting the edge part. CONSTITUTION:CNC data in the previous block stored in a CNC data buffer are investigated, and in the cases the interpolation command between an input data and the previous block is straight line-straight line (6-4), straight line-arc line or arc line- straight line (6-5) and arc line-arc line (6-6), check whether this position is the edge part or not, is executed. In the case of the straight line-straight line (6-7), and in the case these are not the same straight line, this is made to the edge part. In the case of the straight line-arc line or the arc line-straight line (6-8) and in the case these are not the corner R, this is made to the edge part. In the case of the arc line-arc line or the arc line-straight line (6-8), and in the case these are not the corner R, this is made to the edge part. In the case of the arc line-arc line (6-9), too, and in the case these are not the corner R, this is made to the edge part. In the case of deciding that this position is the edge part after the above checking of (6-9), the automatic deceleration command cord is added to the previous block. After that, machining condition is added to the previous block, and the data are inputted into an outer storing device. |
