Conversational programming on the CNC was developed in the early 1980s and is popular in many job shops, maintenance shops and tool rooms. In these shops, parts are machined in small quantities, and jobs are changed frequently. Manual G code programming can be very effective for some simple machining processes, such as face milling. However, it has two main drawbacks. First, G code programming is not intuitive and requires a lot of training. Many machine operators are intimidated by G code and are not willing to learn G code programming.Conversational programming on CNC was developed to solve the inefficiencies of manual G code programming and offline CAM software. A good conversational programming is intuitive, simple, and yet capable of programming simple to complex parts. Conversational programming on CNC becomes a very effective programming tool for many machine shops that manufacture parts in small to medium lot sizes. Graphical Program Input The geometry input should be more graphical and less descriptive. This makes the input very intuitive. The following is an example for bolt-hole pattern input. Solid model (3-dimensional) simulation Solid model simulation can provide an overall check for a part program, and give the operator the confidence to run the part program. Zoom function Zoom function should allow zoom in (enlargement) and zoom out (reduction). Zoom out is very useful to check auxiliary tool movements, such as tool change position. G Code Conversation Capability Conversational programming is always expressed in macro statements or in plain English like language.
