In front of the turret with rear turret in the car to count the G41G42 cutter compensation when there is no difference?
The operator is standing in front of the numerical control lathe, the cutter head is located between the main shaft and the operator. When the tool spindle is rotating, the tool head is turned upward, and the cutter head is rotating. The front and rear turret turret programming is the same, clockwise and counterclockwise circular interpolation G02 interpolation G03 direction is right according to the Descartes coordinate system, first determine the positive direction of the Y axis, and then from the positive direction of Y in the negative direction seems to determine the positive direction of the X axis, and then determine the G02 and G03 in the direction of the XZ plane can be, in front of the turret Y positive axis down, rear turret Y positive axis upward. No matter what the system is the same, if you in the right direction according to the right to see Descartes coordinate system can determine G02 and G03 in the front and rear turret style the same, the Y axis is a virtual axis lathe, there is practically no Y axis.
There are two forms of the lathe tool holder arrangement:(1) turret. The front tool rest is located at the front of the Z axis, the same as that of the traditional horizontal lathe tool holder, the tool holder guide rail is a horizontal guide rail, and the utility model adopts a four position electric tool holder;(2) post holder. The rear turret is located behind the Z axis, and the position of the guide rail frame is a inclined plane, this structure is convenient to observe the cutting process, the chip can be easily removed, rear space, turret can design more station, general multifunctional CNC lathe.
The turret of the numerical control lathe is the front knife holder in the operator's side. The common lathe is the rear cutter. When the tool head, the G42 tip radius compensation right bias in the car when the hole, when the car is round with G41.
