13. Program Support Functions
13.6 G Command Mirror Image; G50.1, G51.1 / G62
Function and purpose
When cutting a shape that is symmetrical on the left and right, programming time can be shortened
by machining the one side and then using the same program to machine the other side. The mirror
image function is effective for this.
For example, when using a program as shown below to machine the shape on the left side, a
symmetrical shape can be machined on the right side by applying mirror image and executing the
program.
