Getting The Most From A CNC Swiss-Type

About a year and a half ago, when the company was looking to cut cycle times and increase precision by eliminating costly secondary operations, it decided to invest in complex CNC Swiss machines from Marubeni Citizen-Cincom (Allendale, New Jersey). It didn't take long for Amphenol to realize how important an efficient programming scheme was in the pursuit of achieving the potential productivity enhancements its new Swiss machines offered.

Based on a recommendation from its machine dealer, Amphenol automated its CNC programming through the use of a CAD/CAM system called PartMaker SwissCAM from PartMaker Software. (Fort Washington, Pennsylvania). The software is a visual CAM system developed specifically around the needs of multi-axis and Swiss-type lathes.

It operates from graphic representations of various faces of the part. Lenny Bennett, CNC production supervisor at Amphenol, decided to begin using the software after the new Citizens had been on the floor for over a year. According to Mr. Bennett, the company was able reduce setup time by more than 50 percent within the first 30 days of using the system by creating programs that were correct the first time and required little or no operator intervention or editing once sent to the machine.
"The setup of these machines is really quite easy once you have a good program," Mr. Bennett says. "With SwissCAM we're making programs now that run the first time."
