When G41 G42 is running in the CNC lathe of the wide number system, what is the reason for the overc

A module has been changed or has an error due to a stop or cancellation in the middle of the program.

CNC lathes. It is the abbreviation of digital program control lathe, which integrates the characteristics of universal lathe, precision lathe with high processing accuracy and special lathe with high processing efficiency, and is the largest and most widely used CNC machine tool in China. The typical parts processed by CNC lathes are generally shaft sleeve parts and disc parts, which have the characteristics of high machining accuracy, high efficiency and high degree of automation.

Classification

CNC lathes can be divided into two categories: horizontal and vertical. There are two kinds of horizontal lathes: horizontal guide rail and inclined guide rail. High-grade CNC horizontal lathes generally use inclined guide rails.

According to the number of tool holders, it can be divided into single tool holder CNC lathe and double tool holder CNC lathe, the former is two coordinate control, and the latter is four coordinate control. Most of the double turret sleeper cars use inclined guide rails.

Wide number system CNC lathe.

The end face of the car uses G41G42, which refers to the left knife and the right knife respectively, which is no problem. What you mean should be how and when to use it. When the machine tool moves, along the direction of the tool movement, the tool uses G41 on the left side of the workpiece, and G42 on the contrary, this movement refers to the initial movement.

The value of the tool compensation can be positive or negative, and can be used for rest cutting, semi-finishing, etc. T3 is the position number of the tool It should be the arc radius of the tool tip.

For example: t0101 m3 s400 g0 x50z2g42) g1 z0

x52 z-1

z-15x60g40） g0 z160

M30 assumes) that the radius of the arc of the tool is, using the T3 orientation, the outer circle of the car.

If the tip is not compensated, the above procedures are normal except for the chamfer, but when the compensation is used, except for the chamfer and x, the size is normal, and the z-value will change. That is to say, when the first chamfer, arc, and cone are finished, the Z value changes, so in the above program, Z must subtract a tip radius, so Z-15 needs to be changed to subtract a tip radius, T5 T8 does not need to be reduced, T0, T9 I don't know, I have never used it
