Mastercam函数opinfo用法之获取刀具加工及操作最大加工深度

上一篇文章分享了通过opinfo函数获取全局最大最小值，下面的代码将通过opinfo函数获取每个刀具及每个操作的最大最小值，相较于其他方法，这个更直观，同时扩展性也更好。

特别说明：

此最大最小值仅适用于在换刀位置输出，不支持在程序头刀具清单里面输出

后面将会发布获取全局，刀具，操作X，Y最大最小值的相关代码。

以下为输出效果：

代码和步骤正式开始：

1：在任意2个代码块之间增加以下代码，如有重复，需要更名。

以下代码为获取单个刀具最大最小值，多次调用，会有多次不同的结果。

pcomm_max_min_for_tool
      z_min_tool = opinfo(19, 0)
      z_max_tool = opinfo(16, 0)
      loop = 1
      result = opinfo(92, loop)
      while result = 1000,
        [
        z_min_op = opinfo(19, loop)
        z_max_op = opinfo(16, loop)
        if z_min_op < z_min_tool, z_min_tool = z_min_op
        if z_max_op > z_max_tool, z_max_tool = z_max_op
        loop = loop + 1
        result = opinfo(92, loop)
        ]
      "MAX TOOL Z = ", *z_max_tool, e$ 
      "MIN TOOL Z = ", *z_min_tool, e$ 

2：在任意2个代码块之间增加以下代码，如有重复，需要更名。

以下代码为获取单个操作的最大最小值。

pcomm_max_min_op  
      zmin_op = opinfo(19, 0)
      zmax_op = opinfo(16, 0)
      "MAXIMUM OPERATION DEPTH = ", *zmax_op, e$ 
      "MINIMUM OPERATION DEPTH = ", *zmin_op, e$ 

3：在psof$，ptlchg$ 换刀代码前增加如下代码：

pcomm_max_min_for_tool
pcomm_max_min_op 

4：在ptlchg0$增加如下代码：

以下代码可能还需要判断当前操作和前一个操作的id是否相同

pcomm_max_min_op
