Acu-Rite CNC 3500i user manual Diameter Offset in Tool Table

4.2 Tool Data

With the tool in the spindle, carefully jog the tool down until it touches the top surface of the work piece. This is referred to as “Part Zero”.

Touch the Teach button. The 3500i calculates the tool length offset for the selected tool putting the data to the length column.

Press the Enter button to save the data entered in the field.

Diameter Offset in Tool Table

When you activate a tool, you automatically activate the length offset and diameter values recorded on the Tool Table. When a tool is activated, the length offset is applied immediately to provide an accurate Z-axis position display.

The active diameter value is important when you program compensated moves and use cycles with built-in tool compensation. If tool diameter is correct, compensated moves and cycles are executed accurately.

Enter tool-length offsets and tool diameter values on the numbered lines of the Tool Table. The numbered lines on the Tool Table identify the tool number (T-Code) that activates those values.

You can program a tool activation as a separate block or include it within the block for most moves and cycles. Tool activation's programmed, as separate blocks are easier to find in a Program Listing.

The Tool Table can store information for up to a number of tools specified by the machine builder.

On machines equipped with collet-type tool holders, it is impractical to use the Tool Table to store tool-length offsets. You can set tool-length offset at tool change. Tool Table diameters are still required for compensated moves and when using cycles that have built-in compensation. You can run all Jog features from the Tool Table.

Tool Table offsets activate when you program a T-Code.
