Technical Information for Multi Functinal Tools Series 4 Turning and Grooving O Selection of insert Feed rate Depth of cut - Decide maximum feed rate after considering the insert’s characteristics and machine capabilities (Fmax = W x 0.075) - Max feed rate should not be larger than the corner radius of the insert - In grooving applications, chip evacuation problems can be remedied by using step feed methods at small intervals - The minimum depth of cut should be bigger than corner radius of insert - When deciding on the max depth of cut please considerthe machine’s cutting load - Depending on the shape of the insert, deflection of work piece and clearance angle can be changed O Notice for turning KGT/MGT tools are designed to incur side cutting force from its clearance angle; this feature gives you advantage over a standard ISO insert The standard MGT insert also provides a “wiper" effect to improve surface roughness O Noticeforfinishing (offset need final quality) After desired diameter is grooved, continuous turning operation might cause some deflection of the workpiece. In these cases follow the given formula, offsetting these factors enables the desired diameter that you want To eliminate the difference in the machined diameter by utilizing the clearance angle (which is commonly generated during the final turning operation) follow the directions above when machining To obtain a good surface roughness without offsetting in an application follows the directions below 1) Groove to the desired diameter 2) Pull the tool backs a total distance of 0/2 3) Continue the external turning operation to desired diameter Hi YY L O Notice for MGT turning applications KGT/MGT tools are available for grooving and turning as a multifunctional tool. When using a M.G.T tool keep in mind that the tool imitates a standard ISO turning application. The application uses a positive clearance angle where a tool’s cutting force and depth of cut are all applied in an application. This might create normal wear on the insert, after turning, a grooving process might not meet the desired diameter on the work piece. To off set this, adjust the tool 0.004 inches and return to the original position of the grooving application Incorrect usage O Machining workpiece with a radius bigger than the insert’s corner radius corner radius of insert (shown in the picture). The unequal cutting force might initially break the insert or holder 1 0 TZ r 0 Multi functional Tools
