Tool offsets, grinding-specific

Tool offsets, grinding-specific

Function

Grinding-specific tool offsets are available for grinding technology:

• Minimum wheel radius
• Maximum speed
• Maximum surface speed

When cutting edges are created for grinding tools (tool type 400 to 499), these are stored automatically for the tool in question.

Tool type

400

Surface grinding wheel

401

Surface grinding wheel with monitoring

403

Surface grinding wheel with monitoring and without tool base dimensions for grinding wheel surface speed

410

Facing wheel

411

Facing wheel with monitoring

413

Facing wheel with monitoring and without tool base dimensions for grinding wheel surface speed

490 ... 499

Dresser

The TMON command activates geometry and speed monitoring for grinding tools, types 400 to 499, in the part program of the CNC. Monitoring remains active until deactivated in the part program with TMOF. The actual wheel radius and the actual wheel width are monitored.

The speed setpoint is monitored cyclically against the speed limit value, taking into consideration the spindle override. The speed limit value is the smaller of the values resulting from comparison of the maximum speed with the speed computed from the maximum grinding wheel surface speed and the current wheel radius.

Benefits

• Grinding-specific tool offset data for the grinding technology

→ Grinding wheel surface speed, constant
