"Some of our parts are $5,000 to $50,000 in value," says Shawn Eisenschenk, manufacturing engineer. To ensure that short runs of high-value parts a r e e f f i c i e n t , s e t u p times need to be short a n d t h e m a c h i n i n g n e e d s t o b e f r e e o f errors. T he company had been using a simu- lation program included with its CAM package to validate that its pro- grams appeared free of errors, and once the program was validated, a postprocessor would translate it into G code. " W e 'd r u n o u r o w n posts and get G code," Mr. Eisenschenk says. However, the company realized that the CAM system's pre-G-code s i m u l a t i o n d i d n o t always accurately show t h e p o s i t i o n i n g a n d movement of the actual machine and tools in use. If the G code gen- e r a t e d u n e x p e c t e d machine motion or other e r ro r s, th e p ro b l e m s might not be apparent until the machine ran the par t, even though the program appeared to be error-free in the CAM simulation. To resolve the issue, Kurt acquired NCSimul NCSimul uses 3D graphics to help users avoid machining crashes, and its algorithms and embedded process-based knowledge can optimize cutting conditions. Leistritz Advanced Technologies Corp. 165 Chestnut Street, Allendale, NJ 07401 • 201 934-8262 www.leistritzcorp.com • staff@leistritzcorp.com Leistritz has developed internal whirling, a process to cut long internal threads without tilting the tool at helix angle. The method utilizes the bore to support the carbide or CBN cutting tool for extremely accurate profiles and overall geometries. This special purpose machine, model LWN-120-IW, has high frequency oscillation to cut threads with high helix angles and/ or multiple starts. Give us a call or send us an email with your specific application, we know you will be impressed with this outstanding machine's capabilities. The New Method To Cut Precision Internal Threads
