Design Improvement Study For cBN Coated Cutting Body Used In Piston Ring Cutting Process
Journal Title: American journal of Engineering Research - Year 2018, Vol 7, Issue 2
Abstract
In this study, the quality of non-alloy, non-heat treated, gray cast iron workpieces with lamellar graphite was compared with the cutter body with cubic boron nitride (cBN) coated with different hot work steel tool designs.As an alternative to the current single piece cutter body design, a multi-piece modular cutter body has been designed and used.Cutting process is done with INDEX brand automatic CNC cutting machine. Cutting heights and parallelism of the produced samples were measured with GOETZE special design ring height measuring device and surface roughnesses were measured with MAHR brand MARSURF XR1 model surface roughness meter.It has been found that two different body designs also produce similar results on product quality.No significant difference was observed between the ring height, parallelismand surface roughness values.This result shows that the newly designed multi-piece modular cutter body can be used while maintaining the current product quality.In this way, by using the multi-piece modular cutter body, it will be able to reduce setup time, cutter tool scrap rates and cut off all product dimensions with minimum stock level.
