MASSO provides eight Corner Probing cycles.

Four cycles are used for inside corner probing, and four cycles are used for outside corner probing.

The probing cycle you select depends on whether you are probing the inside or outside corner of a part.

Selecting Inside or Outside Probing

First, select Inside or Outside probing by pressing the Inside/Outside button on the Probing screen.

Next, press the Save Settings button to apply the change.

Offset Compensation

The X and Y Offset values can be used to compensate for alignment errors or to offset the probe position if the probe is not located directly under the spindle. 

Probing Order and Position Settings

Each corner probing button displays a dotted white line that indicates the order in which probing will occur.

The X Position and Y Position fields define the working coordinate of the surfaces at the point of probe contact. 

Stopping a Probing Cycle

A corner probing cycle can be stopped at any time by pressing the same probing cycle button again or by selecting a different probing cycle.

Work Offset Selection

From software version 5.0 and later, the probing result can be applied to a selected work offset.

The required work offset must be selected before starting the probing cycle.

Only the selected work offset will be updated by the probing result.  

Inside Corner Probing

For inside corner probing, the red dot represents the probe position at the start of the probing cycle.

The probe moves toward the yellow lines, which represent the surfaces being probed.

The dotted white line indicates the order in which the probing sequence will occur.

Each inside corner probing cycle is an automatic two-stage probing process.

Probing occurs at the feed rate specified in the Probing Feedrate field.

After each probe contact, the axis returns to the starting position at rapid speed.

The Probe Diameter value must be entered into the Probe Diameter field.

Inside Corner Cycle -X then +Y

The probe moves in the -X direction at the specified probing feed rate until it contacts the part.

The probe returns to the starting position.

The probe then moves in the +Y direction at the specified probing feed rate until it contacts the part.

The probe returns to the starting position and updates its coordinates based on the probed surfaces.

Inside Corner Cycle +Y then +X

The probe moves in the +Y direction at the specified probing feed rate until it contacts the part.

The probe returns to the starting position.

The probe then moves in the +X direction at the specified probing feed rate until it contacts the part.

The probe returns to the starting position and updates its coordinates based on the probed surfaces.

Inside Corner Cycle +X then -Y

The probe moves in the +X direction at the specified probing feed rate until it contacts the part.

The probe returns to the starting position.

The probe then moves in the -Y direction at the specified probing feed rate until it contacts the part.

The probe returns to the starting position and updates its coordinates based on the probed surfaces.

Inside Corner Cycle -Y then +X

The probe moves in the -Y direction at the specified probing feed rate until it contacts the part.

The probe returns to the starting position.

The probe then moves in the +X direction at the specified probing feed rate until it contacts the part.

The probe returns to the starting position and updates its coordinates based on the probed surfaces.

Outside Corner Probing

When Outside Corner Probing is selected, two distance fields are displayed at each corner.

These distance values define how far the X and Y axes travel around the corner before the second probing move begins.

The red dot indicates the probe start position, and the yellow lines represent the surfaces being probed.

The white arrow indicates both the probing order and the direction of probe travel.

Each outside corner probing cycle is an automatic two-stage probing process.

Probing occurs at the feed rate specified in the Probing Feedrate field.

After probe contact, the axis returns to the appropriate start position at rapid speed.

The Probe Diameter value must be entered into the Probe Diameter field.

Outside Corner Cycle +X then -Y

The probe moves in the +X direction at the specified probing feed rate until it contacts the part.

The probe returns to the starting position.

The probe moves in the +Y direction and then in the +X direction for the distances specified in the distance fields.

The probe then moves in the -Y direction at the probing feed rate until it contacts the part.

The probe returns to the second probing start position and updates its coordinates based on the probed surfaces.

Outside Corner Cycle -Y then -X

The probe moves in the -Y direction at the specified probing feed rate until it contacts the part.

The probe returns to the starting position.

The probe moves in the +X direction and then in the -Y direction for the distances specified.

The probe then moves in the -X direction at the probing feed rate until it contacts the part

.

The probe returns to the second probing start position and updates its coordinates based on the probed surfaces.

Outside Corner Cycle -X then +Y

The probe moves in the -X direction at the specified probing feed rate until it contacts the part.

The probe returns to the starting position.

The probe moves in the -Y direction and then in the -X direction for the distances specified.

The probe then moves in the +Y direction at the probing feed rate until it contacts the part.

The probe returns to the second probing start position and updates its coordinates based on the probed surfaces.

Outside Corner Cycle +Y then +X

The probe moves in the +Y direction at the specified probing feed rate until it contacts the part.

The probe returns to the starting position.

The probe moves in the ?X direction and then in the +Y direction for the distances specified.

The probe then moves in the +X direction at the probing feed rate until it contacts the part.

The probe returns to the second probing start position and updates its coordinates based on the probed surfaces.

CAUTION: It is advisable to quickly test your touch probe before starting a probing cycle to ensure it is working properly. This is done by triggering the Probe and observing the indication at the top of the screen. When triggered the indication will change green This is done by touching the probe tip in case of a 3D touch probe or by tapping the plate against the tool in case of a probing plate.
