Introduction

This application note describes the setup of dual rotary AB table for 5-axis TCP machining.
The TCP capability is provided by a separate BIN file. Without this file the machine can work as a regular 5-axis non TCP machine.

General

H-Modes

H5 should be used for all programs that requires TCP. In this mode the XYZ coordinate system is that of the part, not the machine. Drilling canned cycles move Z only.
In Manual, H5 moves the machine XYZ, same as drilling, and H3 is used to move in the part coordinates.

Preparation

This set up can be performed by a superuser only.
To avoid unintentional set up, the superuser has to change the security level in plc@50 to 0.
In MDI type: @50=0
Line numbers for setup data relate to the machine.cnx file, in the machine data area after line n30000.
Before you start:

Setup general

To set the machine zero for an axis proceed as follows (X is used as an example):

Notes:

Setup A-axis

Setup B-axis

Setup XY

Setup Z
