Two theoretical supports for chamfering programming of CNC lathes

In the field of CNC lathe programming, there is often a legendary existence. Having a good machine is not as good as having a good set of programming. Reasonable and fast programming ideas not only have great advantages in work efficiency but also cannot be compared in improving machine performance. Today, our CNC lathe manufacturer will mainly explain the two theoretical supports for CNC lathe chamfering programming.
1. Inverted right angle format after straight line: G01X (U) _Z (W) _C_; Function: Straight line followed by a right angle, instruct the tool to move from point A to point B, and then to point C. Explanation: In absolute programming, X and Z are the intersection points of two adjacent lines, which are the coordinate values of point G. U. W: In relative programming, it is the distance traveled by point G relative to the starting point A of the linear trajectory. C: It's a chamfer. When calculating at 60 ° 1:057745 ° 1:130 ° 1:173220 ° 1:274715 ° 1:373210 ° 1:5671, the formula is the Pythagorean theorem in trigonometric functions: In any right angled triangle, the sum of the squared lengths of the two right angled sides is equal to the squared length of the hypotenuse, which is called the Pythagorean theorem.
2. 07 refers to the distance of Z. When programming on a CNC, the angle is reversed by 45 degrees, and the Z-axis is half of the X-axis. For example, for programming the chamfer of an outer circle: if the outer circle X30 is inverted by 07 times a 45 degree angle. G0X276Z05G1X30Z-07F50。 Z05 is located 50 threads away from the product, X276 is because Z starts from 05, so 05 plus 07 equals 12, and then subtract 30 (12 multiplied by 2). 60 degrees is called a equilateral triangle, and c is the right angle side length of a 45 degree equilateral right triangle, also known as XZ. R=(r+radius of the blade) × 2. The convex arcs are all added blades, while the inner arcs are reduced blades. If it is a fillet, you can choose to use the G02/G03 command to complete it, or you can directly use the G01 straight-line fillet command. G02/G03 is generally used for larger radius fillets. The usage is G02/G03X_Z-R_XZ as the endpoint of the fillet, and R as the radius. The straight-line fillet command is widely recommended to be used. G01X_Z-R_XZ is the first two corners of the fillet.
The above are the two theoretical supports for chamfering programming of CNC lathes. We hope that the above explanation can be helpful for everyone in future CNC lathe programming.
