General Precautions

When you program tool path instead of part edge, a negative diameter in the Tool Table effectively changes the moves during compensation.

Third axis moves (not in the active plane) are permitted during compensation.

The CNC automatically rounds off the compensated intersection of acute angles of 15 degrees or less. To change this value, program #1031.

It is possible to change the tool diameter currently in use with “stock” variable #1030.

Startup (Ramp On) and cancellation (Ramp Off) blocks must be at least the tool radius in length.

You must enter proper diameter value in the Tool Table before you use tool compensation.

Compensated arcs must be on the active plane (XY, XZ, = YZ).

Fixture Offset and Zero Set are not permitted during compensation.

In Manual Data Input Mode, any active compensation deactivates.

Jog/Return is permitted during compensation.

System variable #1032 is available to change the number of blocks the CNC can “look-ahead” while in tool-comp. This is used for collision detection.

Changing this value can change the compensated tool path. This variable enables further look ahead to prevent undercut (excessive tool diameter). At default, the CNC looks ahead far enough to find a valid intersection between the current and next move. Set the variable #1032 before you turn on the compensation.
