Regulation of lathe coordinate system and direction of movement

2019-05-23 09:48:10 AM

1. Always assume that the workpiece is stationary and the tool moves relative to the workpiece.

2. The coordinate system uses a right-handed Cartesian coordinate system. As shown in the figure, the direction of the thumb is the positive direction of the X axis, the index finger is the positive direction of the Y axis, and the middle finger is the positive direction of the Z axis. After the X, Y, and Z coordinates are determined, according to the right-hand spiral rule, the directions of the three rotation coordinates of A, B, and C can be easily determined.

3. The movement of the specified Z coordinate is determined by the main shaft transmitting the cutting power. The coordinate axis parallel to the main axis is the Z axis. The X axis is horizontal.

4. It is stipulated that the direction of the tool away from the workpiece is the positive direction of the coordinate axis.

When the lathe is a front tool post, the X axis is forward and forward, pointing at the operator. When the lathe is a rear tool post, the X axis is forward and backward, away from the operator.
