In recent years, macro programs have been created to replace the practice of writing a separate program for every part number. The reason: Macro programs react to geometric variations across broad part families and therefore are more efficient compared with NC programs that are dedicated to particular parts. Using these macro programs often results in higher productivity.
With macro programs, in many cases, an operator does not need to rely on a programmer anymore, but instead can input the correct geometric variables to describe the part for the appropriate macro. The macro generates the correct tool paths according to the entered part variations. Operators are more interchangeable when using macro programs, too, because both experienced and inexperienced operators can initiate the machining process as needed with a similar outcome.
By implementing macro programming, many shops can make their process leaner. Read about a shop that, by using this type of programming, realized a 40-percent increase in productivity on one of its CNC machines. The company’s scrap rate dropped to one-fifth of what it used to be, as well. Visit “Macro Economics” to learn more.
