比如,车削一根轴,轴的外径是100,以端面为零点编程。刀片采用CNMG120408,即刀尖半径为0.8,如果为直径编程:
1、按照刀具中心输出程序,车端面时Z0.8,车外圆时X101.6-------这是我想要的
2、按照理论刀尖输出程序,车端面时Z0,车外圆时X100-------------目前输出的是这种情况
3、模拟的时候,刀路是按照刀具中心绘制的。可是输出程序后,确变成了刀尖。
下面是软件帮助的原文:
1. Tool Tip
The system draws the toolpath to the center of the tool tip radius. The X and Z-axis values are output to the theoretical tool tip if the system is able to calculate a touch-off point in both axes. X or Z-axis values are output to the center of the tool tip radius when the software is not able to calculate the touch-off point in that particular axis.
If the tool is machining parallel to the Z-axis, the X values are output to blueprint dimensions. If the tool is machining parallel to the X-axis, the Z values are output to blueprint dimensions. So, the theoretical tool tip only aligns with blueprint dimensions on faces and diameters.
When the tool is machining at an angle, the X and Z-axis values will not match the blueprint dimensions. This is because the theoretical tool tip is not always a blueprint dimension. So, in order for the system to get the surface of the tool in position to cut the part, the theoretical tool tip is calculated closer to the part, and in some cases inside the part.
Most Lathe Posts output X and Z values to the theoretical tool tip. Posts can be modified to output X and Z values to the center of the tool tip radius. |
