Is Manual Programming Really Important?

I am often questioned about the scope of this column. The most common question is: "Why do you continue to discuss manual programming techniques when almost all companies are using CAM systems?" Aside from the fact that other columnists are address...


Finding The Current States Of Your Control

You probably know that most current CNC controls will display all currently instated modes (commonly set by G codes). With one popular control, this is part of the program check display screen function.


How Should Your Operators Handle Sizing Changes?

All current model CNC controls allow offsets to be changed during the execution of the CNC program. That is, operators can change an offset during a production run while the machine is running.


Shifting Program Zero On Machining Centers

It is common to machine several identical workpiece attributes from within a single program. Consider the four identical circular counter-bored holes that must be milled in the workpiece shown in Figure 1.


Inventing Wear Offset Compensation

You know that machining centers have tool length compensation, cutter radius compensation and fixture offsets. Turning centers have geometry offsets, wear offsets and tool nose radius compensation.


A Flexible Turret Index Position

The cutting tools in your turning centers change on a regular basis. To minimize tool change time during setups, many setup people will simply load the tools required for the new job and leave tools in the turret from the last job as long as they d...


Combining Absolute And Incremental Motions

While we agree that the absolute mode should be your positioning mode of choice for most applications, there are times when incremental mode can be quite helpful. Repeating motions within a subprogram, for example, is one excellent example.


A Realistic Definition Of Cycle Time

Many people determine cycle time by measuring cycle start to cycle start time. As the operator presses the cycle start button, he or she starts the stopwatch.


Which Is Faster, G00 or G01?

Special thanks to Kyle A. Thornley, Technical Instructor at GE Fanuc Automation, for explaining the principles described in this article.


Eliminating Calculations For Offset Entries

Almost every offset entry requires some kind of calculation to be made before the offset value can be entered. Say, for example, the target diameter for a turning tool is 3.
