OA=300//               distance between the fixed centres in mm
OB=150//                 length of driving crank in mm
//================================
OAB=asind(OB/OA)//              inclination of slotted bar with vertical in degrees
beeta=(90-OAB)*2//               angle through which crank turns inreturn stroke in degrees
A=(360-beeta)/beeta//             ratio of time of cutting stroke to the time of return stroke
