Acu-Rite CNC 3500i user manual Tool Radius Compensation, Contouring without radius compensation

Tool Radius Compensation

When tool compensation is not active, the CNC positions the tool's center on the programmed path. When programming a part profile, the cutting edge must be half a diameter away from the path. Using radius compensation moves the cutting edge half a diameter away from the path.

When tool compensation is active, the CNC offsets the tool by half a diameter to position the cutting edge of the tool on the programmed path.

This enables you to program the coordinates along the part profile. You do not need to adjust the path to compensate for tool diameter.

Most moves can be compensated. Specify right-hand or left-hand compensation. “Right” or “Left” refers to the side of the path to which the tool offsets, as viewed from behind a moving tool. If the tool is to the left of the work, use Left (G41). If the tool is to the right of the work, use Right (G42). Refer to chapter 11 "G-Code" on page 364.

Use tool compensation with lines and arcs only.

Contouring without radius compensation

The tool center moves in the working plane along the programmed path or to the programmed coordinates.

Applications: Drilling and boring, pre-positioning.
