Re: [MW:15132] cause of crack

Dear suresh
First of all check if all parameters of WPS are followed..once this is confirmed n found ok check for WEP,as this seems a lameller tearing..so instead of making single side groove on one part,suggested to have WEP inclusive of both the part..i am sure your problem will not repeat..
