I. Overview

Renishaw GoProbe is a simplified and standardized CNC tool setting programming solution. Unlike the complete O985x macro program series (Haas VF specific), GoProbe uses a unified entry macro program to select different measurement modes through functional code, greatly reducing programming complexity and memory burden on operators.
The GoProbe contact type tool alignment system supports three hardware platforms:
| Model | Transmission Method | Typical Interface | Repetitive Accuracy | Typical Applications |
|: ——— |: ——- |: ——- |
|TS27R| Wired (Hardwired) | MI 8-4/HSI/HSI-C |1.00 μ m 2 σ| Three axis machining center, reliable and stable |
|RTS| RF FHSS 2.4 GHz | RMI-Q |1.00 μ m 2 σ| Five Axis/gantry, where wiring is not possible |
|OTS| Infrared optics (dimming) | OMI-2/OMI-2T/OMI-2H/OMM-2C+OSI |1.00 μ m 2 σ| Multi spindle/switching worktable, wireless flexibility |
All three types of tool presetters use the same probe structure and triggering principle, The GoProbe programming interface is completely consistent – the same piece of code can run on three types of hardware without discrimination.

1.1 Basic requirements for installation of tool setter

The tool setter is fixed on the workbench with M12 T-bolts and can be used with Spirol positioning pins to achieve repeated positioning

Recommended measuring needle: Hard alloy disc type measuring needle (75 HRC) or square ceramic measuring needle, with a length of 35 mm as standard configuration

Connect the signal cable (TS27R) or receiver (RTS/OTS) to the skip signal input of the CNC system

The interface unit provides trigger signal conditioning，Usually connected to CNC 的 SKIP（G31） Input

1.2 Offset setting for the installation position of the tool setter

After the installation of the tool setter, the installation position offset needs to be correctly set in the CNC system. For the Fanuc system, the working position coordinates of the tool setter are usually recorded using the# 5xxxxseries of macro variables:

; Example of setting the installation position of the cutting instrument（FANUC/Meldas）
#501 = 350.0 ; The tool setter in the machine coordinate system X Position (mm)
#502 = 215.0 ; The tool setter in the machine coordinate system Y Position (mm)
#503 = -150.0 ; The tool setter in the machine coordinate system Z Position (mm) — Surface height of disc-shaped measuring needle
#504 = 25.0 ; Disk type measuring needle diameter (mm)

These variables are referenced by internal macro programs in the calibration and measurement cycles and need to be set on-site according to the actual installation location.

2、 GoProbe entrance macro and functional code system

2.1 Fanuc/Meldas system

FANUC/Meldas System Usage G65 P9921 As a unified entrance，Through M codeSelect sub functions：
| M code | function | Explanation |
|:—|:—|—:|
| M21 | Blade length measurement（Tool Length Measurement） | Measure the current spindle tool Z Towards length |
| M22 | Blade Length + Diameter measurement（Tool Length + Diameter Measurement） | Simultaneously measure the length and diameter of the cutting tool/radius |
| M23 | Broken Tool Detection（Broken Tool Detection） | Check whether the cutting tool is broken or worn out of tolerance |
| M24 | Calibration of tool calibration（Tool Setter Calibration） | Calibration tool setter Z 和 XY Reference Position |
⚠️ Important Notice：在 GoProbe In the official system，Comprehensive calibration of the cutting instrument（ZAxis height and XY offset）Unified integration in M24（Siemens is R0=24）In the functional code。Please do not associate with early machine tool factories OEM Separate checks in customized macro programs/Confusion of calibration codes，Everything is subject to this manual。

2.2 Siemens 840D System

The Siemens 840D system uses a separate SPF subroutine file and selects sub functions through theR0 parameter. The sub functions are:
| R0 value | Function | Description |
|: ——– | ——-: |
|R0=21| Tool length measurement | Measure the Z-direction length of the current spindle tool |
|R0=22| Tool length+diameter measurement | Simultaneously measure length and diameter |
|R0=23| Tool breakage detection | Detect whether the tool is broken |
|R0=24| Calibration of tool setter | Calibration of tool setter reference position |
⚠️ Important note: In the official GoProbe system, the comprehensive calibration of the tool gauge (Z-axis height and XY offset) is uniformly integrated into the M24 (Siemens R0=24) function code. Please do not confuse the inspection/calibration codes separated from the early OEM customized macro program of the machine tool factory. Please refer to this manual for everything.

2.3 Function Code Comparison Table

function	Fanuc M code	Siemens R0 value
Blade length measurement	M21	R0=21
Blade length+diameter measurement	M22	R0=22
Broken Tool Detection	M23	R0=23
Calibration of tool calibration	M24	R0=24

3、 Calibration of tool calibration (M24/R0=24)

Calibration must be performed after the installation of the tool gauge or replacement of the measuring needle. The essence of calibration is to make the CNC system “remember” the precise position (Z height and XY center) of the tool disk type measuring pin in the machine coordinate system.

3.1 Calibration principle

Use a standard tool with known length and diameter (calibration rod) for calibration, and complete the following steps:

Z-axis calibration(M24 or R0=24 with A1): Touch the upper surface of the disc type measuring pin of the tool setter with a calibration rod, and the CNC system records the Z-axis offset

XY axis calibration(M24 or R0=24 with A2): Use a calibration rod to touch the four directions (east, south, west, north) of the disc type measuring needle of the tool setter, and the CNC system calculates the XY center position and measuring needle diameter

3.4 Verification after calibration

After calibration is completed, it is recommended to use the calibration rod to run the tool length measurement again (M21/R0=21) to verify the calibration results. The measured value should be consistent with the known length of the calibration rod, and the deviation should be within ± 0.005 mm.

; Calibration verification — FANUC
G65 P9921 M21 T1. ; measurement 1 Number of cutting tools（Calibration stick）

IF [#100 GT 0.005] GOTO 9000 ; If the deviation exceeds the limit, an alarm will be triggered

4、 Blade length measurement (M21/R0=21)

Tool length measurement is the most commonly used function, used to automatically measure the Z-direction length of the tool in the current spindle and write the result into the tool offset table.

4.1 Measurement principle

The tool moves downwards at the set feed rate, and touching the surface of the disc-shaped measuring needle of the tool setter triggers a skip signal. The CNC system records the trigger position and calculates the tool length. After the measurement is completed, the tool automatically retracts to a safe position.

4.2 Parameter Description

The accuracy of diameter measurement is influenced by various factors, and the following are the best practices:

; ==================================================
; High Precision（Mainstream brand probes typically have a one-way repeatability accuracy of 0.25 in machine measurement~1.0µm 2σscope）Example of Diameter Measurement
; ==================================================
; technique 1: Reduce feed rate and improve accuracy（Mainstream brand probes typically have a one-way repeatability accuracy of 0.25 in machine measurement~1.0µm 2σscope）
; For precision machining tools，Use a lower feed rate

6、 Broken knife detection (M23/R0=23)

6.1 Function Description

The tool breakage detection is used to automatically check for tool breakage or severe wear during or after the machining cycle. The detection logic of GoProbe M23/R0=23 is as follows:

The tool moves towards the measuring needle of the tool setter at the set feed rate

The system records the actual triggering location

Compare the actual trigger position with the expected position (based on the original tool length/diameter)

If the deviation exceeds the set toleranceHh, it is judged as a broken tool and an alarm is triggered

6.2 Parameter Description

5.2 Common Measurement Mode Practice (Fanuc/Moldas System Demonstration)

After calibration is completed, the tool setter has high precision (mainstream brand tool presetters usually have a one-way repeatability accuracy in the range of 0.4~1.0 µ m 2 σ) as a measurement benchmark. The following is a complete production example of automatic tool length and radius detection:

5.2.1 Automatic tool length measurement (M21.1 mode)

6、 Installation, positioning and maintenance specifications for Renishaw tool setter

6.1 Requirements for Precise Installation and Positioning

Mechanical base fixation: The TS27R or RTS tool setter base must be rigidly fixed to the rightmost or leftmost corner of the vertical machining center (VMC) or gantry milling machine worktable with M10 metal tension bolts (ensuring that the worktable travel limit can be safely covered and does not hinder the clamping of the fourth axis or large workpieces).

Protection and anti chip design: The tool setter must be installed horizontally, and its built-in metal dust cover should be intact. The chip exhaust pipe (pressure 0.3MPa~0.5MPa, filtration level Class 4) must be connected to automatically blow air to remove chips and cutting fluid from the surface of the probe before each probe trigger..

Anti collision protection (weak pull pin): The probe rod root of the tool setter is equipped with a replaceable high toughness damping fracture part (weak pull pin). When a serious machine collision or misoperation occurs, the pulling needle will break first to protect the piezoelectric probe body of hundreds of yuan from damage. Do not use ordinary stainless steel screws instead of weak pulling needles!

6.2 Common fault diagnosis and on-site troubleshooting methods

Fault phenomenon	Possible reasons	On site diagnosis and elimination measures
The hair detector does not light up the traffic light	1. Battery depletion (RTS) 2. TS27R circuit loose	1. Check the RTS probe battery and replace 2 1.5V lithium batteries. 2. Use a multimeter to check the 24V output of the MI-12 interface box and re tighten the 4-core terminal of TS27R.
When the tool is triggered, there is no Skip signal from the machine tool	1. Skip line (X4.7) disconnection 2. System parameter configuration error	1. On site inspection of system skipping input signal X address changes. 2. Check if FANUC parameter 6200 # 4 is enabled (enabling high-speed skip function).
The accuracy of repeated length positioning is extremely poor (>10 μ m)	1. Residual chips on the surface of the tool setter 2 The probe base is loose Calibration parameters accidentally overwritten	1. Blow clean the upper surface，Adjust the self blowing delay of the knife（G04 X1.0）。2. Use a torque wrench to recheck the fixing screws of the workbench base。3. Run again O2000 Calibration program。

FAQ Selected Q&A

Q: What is the difference between Renishaw TS27R and RTS tool setter?
Answer: The TS27R is a wired version that connects to the MI 8-4 interface box via a 4-core cable to obtain 24V power and transmit signals, making it suitable for fixed installation scenarios. RTS is a wireless version, battery powered (2 1.5V lithium batteries), transmitting signals through radio, suitable for frequent tool changes or situations where wiring needs to be avoided. The triggering accuracy and programming method of the two are completely the same, both are contact triggering mechanisms with consistent repetition accuracy.

问：GoProbeWhat should I do if the calibration program O2000 for the tool gauge cannot be found？
答：O2000It is the main calibration program for Renishaw GoProbe tool setter，Included in the GoProbe macro package。If lost，Need to use RS-232、CFCard or Ethernet reload macro package。Check O2000 after loading~O2030Is the series of programs complete。After calibration, it is recommended to copy the calibration constants to#500~#520Reserve variable area，Prevent power outage and loss。

问：The repeatability accuracy of the tool gauge suddenly deteriorates to 10μmAbove，What should be checked in the first step？
答：Three step investigation：①Clean the upper surface of the tool setter——The most common reason for the change in trigger position of the measuring needle is due to chip adhesion；②Check if the fixing screws of the tool setter base are loose，Lock with a torque wrench；③Confirm that self blowing qigong can function normally（G04 X1.0Is the delay sufficient）。These three steps solve over 90% of the repeatability accuracy problem。
