数控装置和控制方法
摘要：
本发明涉及数控装置和控制方法。数控装置能执行插补型快速进给。CPU对数控程序解释一行，当解释的控制指令是快速进给指令时，对该快速进给指令是否是规定顺序动作的快速进给进行判断。规定顺序动作为例如工具更换指令。工具更换指令是在使主轴头返回至Z轴原点之后通过使主轴头在工具更换区域内升降来进行工具更换的指令。在快速进给指令是规定顺序动作的快速进给指令时，工具不与被切削件或夹具发生碰撞，因此，CPU执行通常的快速进给。因此，数控装置不进行不必要的插补型快速进给，从而能缩短加工周期。
摘要（英）：

The invention relates to a numerical control (NC) device and a control method. The numerical control device can perform interpolation type rapid feed. A CPU interprets a line for a NC program, and when an interpreted control command is a fast feed command, it determines whether or not the fast feed command is a fast feed of a predetermined sequential action. The predetermined sequential action is, for example, a tool change command. The tool change command is an instruction to change a tool by raising or lowering a spindle head in the tool change area after returning the spindle head to the Z axis zero point. When the fast feed command is a fast feed command of the predetermined sequential action, the tool does not collide with a workpiece or fixture, so the CPU performs a normal rapid feed. Therefore, the numerical control device does not carry out unnecessary interpolation type fast feed, which can shorten the machining cycle.
