What is cutter compensation?
What is Cutter Compensation? Cutter compensation (cutter comp), also sometimes called Cutter Diameter Compensation (CDC), provides a way to adjust the toolpath at the machine to compensate for tool size, tool wear, and tool deflection.
What is cutter radius compensation explain with example?
Cutter Radius Compensation (CRC) is used in a program to allow the operator to alter the path of a cutter. Figure 9-1 Cutter Radius Compensation. EXAMPLE: After cutting the part with path 1, the operator measured the part and determined that the part was undersized.
What is cutter compensation cancel?
Cutter Compensation Cancellation (G40) Function G40 is used to cancel cutter radius compensation initiated by G41 or G42. It should be programmed after the cut using the compensation is completed by moving away from the finished part in a linear (G01) or rapid traverse (G00) move by at least the radius of the tool.
What is tool compensation?
Tool compensation determines the machining precision and quality . There are tool length compensation,tool radius compensation and corner radius compensation in CNC system . The parameters of these compensation are all static. The computer program was finished about how to calculate the dynamic parameter.
What is tool length compensation?
As the name suggests, tool length compensation enables a cnc machine to compensate for many tools of different lengths. It allows a machinist to set a Z axis datum on a part and use multiple tools without having to reset the Z datum for each tool used.
What is the 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 tool radius compensation?
Tool radius compensation (TRC) allows programming of the workpiece contour independently of tool geometry. When a negative tool radius is used, the selection side of the TRC is changed automatically. …
What is the purpose of cutter compensation?
Cutter compensation (cutter comp), also sometimes called Cutter Diameter Compensation (CDC), provides a way to adjust the toolpath at the machine to compensate for tool size, tool wear, and tool deflection. When I originally started programming by manually writing G-Code, I used cutter comp to offset the tool by the radius.
How do I turn cutter radius compensation on right?
• 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 to apply cutter compensation on a CNC machine?
We can use two different G-Codes to apply cutter compensation depending on the direction of the cut. G41 is left compensation and G42 is right compensation. On a CNC machine, it is usually recommended to use climb milling, this needs to be taken into consideration when writing our programs and deciding which direction to apply cutter compensation.
What are the G codes used to enable cutter compensation?
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. This is only true for positive diameter offset values.
