What is wear compensation?
Just like “In Control” compensation type, the output code for “Wear” comp includes a G41 (right comp) or a G42 (left comp) to offset the tool by the tool radius from the Diameter Offset Table in the machine control. The output code also includes a G40 to cancel the compensation when the tool path is complete.
What is cutter radius compensation?
Cutter radius compensation compensates for the radius of a cutting tool by causing the controller to maintain a constant offset that is perpendicular to the programmed path in a two-dimensional plane. You can use this feature to compensate for the diameter of a cutting tool or the width of a laser.
What is the wear offset?
Many current-model turning centers have two sets of offsets: Geometry offsets are used to assign program zero during setup, and wear offsets are used to make sizing adjustments during the production run. When users view these offsets on the display screen, they look very similar.
How do you turn on cutter compensation?
To turn cutter radius compensation on right (i.e., the cutter stays to the right of the programmed path when the tool radius is positive), program G42 D~. The D word is optional; if there is no D word, the radius of the tool currently in the spindle will be used.
How does cutter compensation work?
Cutter compensation allows for fine tuning the tool path, and adjustment of part dimensions, without having to change the program itself. There are two G codes used to enable cutter compensation. G41 offsets the tool to the left of the tool path and G42 offsets the tool to the right of the tool path.
What is the difference between geometry and wear offset?
One set, the geometry offsets, is used to help with program zero assignment. The other set, the wear offsets, is used to help with sizing adjustments. Wear offsets, on the other hand, are used to deal with adjustments that cause cutting tools to machine surfaces within their tolerance bands.
How many types of offsets are there?
There are two types of offset printing: wet offset and waterless offset.
