Chapter 5

Protected positioning cycles

When the probe moves around the workpiece, it is important that the stylus is protected

against a collision with the workpiece. This chapter describes how to use macro O9810 to

set up the protected positioning of the probe. After it is correctly set, the probe will stop

moving in the event of a collision.

Protected positioning (probe trigger monitor) - macro O9810

Figure 5.1 Probe protected positioning

Description

It is important when moving around the workpiece to protect the probe stylus against

collision. When this cycle is used, the machine will stop in the event of a collision.

Application

Select the probe and move to a safe plane. The probe should be made active at this point

and then it can be moved to a measuring position using this macro call. In the event of a

collision, the machine will stop and a macro alarm PATH OBSTRUCTED will result, or an

error flag #198 will be set (see Mm input).

Calibration cycles

Before a probe is used, it is important that you calibrate it correctly. This chapter describes

the four macros that you should use for calibrating a probe. If you need to know more

about calibrating a probe, you will find helpful information contained in Chapter 1, “Getting

started”.

Calibration cycles

Calibration cycles - an overview

Four calibration cycles are provided with the Inspection Plus software. These may be

used in conjunction with one another for complete calibration of the probe. The purpose of

each macro is summarised below.

Macro O9801 This is used to establish the probe's length in its tool shank.

Macro O9802 This is used to establish the stylus off-centre values.

Macro O9803 This is used to establish the stylus ball radius values. It is suitable for all

measuring cycles except for O9821, O9822 and O9823.

Macro O9804 This is used to establish the vector stylus ball radius values. It is suitable

for all measuring cycles, including O9821, O9822 and O9823.

For complete calibration of a probe system, you must use macros O9801 and O9802, and

either O9803 or O9804. Examples of full calibration procedures are described in the

sections titled “Example 1 - Full calibration in an internal feature” and “Example 2 - Full

calibration on an external feature” at the end of this chapter.

The Renishaw calibration cycles are split into separate cycles for flexibility. If, however,

the calibration feature is accurately known for both size and position, e.g. a ring gauge

where the size is known, and the position is accurately found using a dial test indicator, it

is then possible for you to write a program which completes the full calibration procedure

in one operation by calling all of the above macros.

Description

The probe is positioned inside a pre-machined hole at a suitable height for calibration.

When this cycle is completed, the stylus offset amounts in the X and Y axes are stored.

Application

Pre-machine a hole with a suitable boring bar, so that the exact centre of the hole is

known. Position the probe to be calibrated inside the hole, and the spindle on the known

centre position with the spindle orientation active. When the cycle is run, four measuring

moves are made in order to determine the X offset and Y offset of the stylus. The probe is

then returned to the start position.

Description

This cycle measures a surface to establish the size or position.

Application

The probe should be positioned with its tool offset active adjacent to the surface. The

cycle measures the surface and returns to the start position.

There are two possibilities as follows:

The surface can be treated as a size, where the tool offset is updated in conjunction

with the Tt and the Hh input.

The surface can be treated as a reference surface position, for the purpose of

adjusting a work offset using the Ss and Mm inputs.
