Fine feed rates and small hole limits

Add or edit optional fine speed settings to the rate table.

Speed diameter and fine cutting rate

The 'fine speed diameter' and 'fine cutting rate' are optional fields, if you have a 'speed diameter' or 'fine cutting rate' of 0, then no fine cutting rates apply. If it's greater than zero, then any hole in a part that is smaller than this will use the fine cutting rate time.

Technical note: In the above, the use of the phrase "any hole in a part that is smaller than this" is comparing the area of the hole in the part to the area of a circle with a diameter of the value entered into the "speed diameter" column.

To add a fine 'speed diameter' or 'fine cutting rate' to an existing thickness, click the edit icon on the last column on right-hand side of the screen:

To add it to a new thickness enter a value in the field, leaving it blank will exclude it from calculations.

When this field is blank or set to zero, ToolBox uses the default cutting feed rate.

Small holes limit

The small holes limit is an optional field, if you have a 'small holes limit' of 0, then no limit applies. If it's greater than zero, then any hole in a part that is smaller than this will result in a warning on the status of the part after you attempt to calculate it:

To add a 'small holes limit' to an existing thickness, click the edit icon on the last column on right-hand side of the screen.

To add it to a new thickness enter a value in the field, leaving it blank will exclude it from calculations.

When this field is blank or set to zero, ToolBox will not display a warning.
