GROOVE-TURNTEXT USER GUIDE Machine Power Calculation Calculation of Required Machine Power M-type Tools • M-type tools have no support under Use the formulas below or use our internet web tool at: the insert’s cutting edge http://mpwr.iscar.com/machinimgpwr • For an insert with a width smaller than 2.2 mm, there are no standard catalog tools available. There are 2 Turning options as to how to use these narrow inserts: P= Kc∙ap∙f∙vch∙ 60,000[kW] 1 Modify an existing tool and adjust the supportunder the insert to the required width 2 Use a standard M-type tool without support • In wider widths, there are also cases where the support R under the insert will disturb machining (threading inserts, pulley-V inserts and various specially tailored inserts) and therefore the above explanation should be considered W • These tools also provide the option for customers to use a very wide range of insert f widths on the same tool (up to 6.4 mm) ap f • Machining conditions need to be light due to little support and limited gripping forces Grooving/Parting Kc Values P= Kc∙W∙f∙vc h∙ 60,000 [kW] Mtl.
