Chapter 1 Introduction

The Graphic Input Interface (GII) is the new function of SynTec 900ME series. This product is designed to edit CNC G-Code program easily. GII is very user friendly and builds in on-line-help that makes the development of CNC program more quickly. Beside these attributes, GII also has built-in Macro Programs, which are very useful to lots of machining procedures. Even first time user can be guided by GII to enter complex arguments correctly without memory any means of arguments. The Figure 1-1 shows the organization chart of GII that describes the relations of options and functions in GII. The shadow square is the main options in GII menu, which includes functions in it. The white square with arc angles means direct input without dialogic box. The black square with arc angles means input arguments with dialogic box. Please refer to Chapter 3 and 4 for more detail information.

This user guide is organized as follows︰Chapter 1 Introduction, describes the main purposes and functions of GII; Chapter 2 GII Operation Flow, use a rapid position as a example to teach user how to use GII; Chapter 3 Basic Machining Functions, includes Rapid Position, Linear Interpolation, Arc Interpolation and cutter setting. Chapter 4 Cycling Machining Functions includes Drilling, Tapping, Facing, and Pocketing and Pattern Positioning.
