Mini project report on
PLANER MILLING MACHINE ACCOMMODATED WITH DRILL HEAD
What is Planer-milling machine?
Planers and shapers are now obsolescent, because milling machines have eclipsed them as the machine tools of choice for doing work, as the rate of metal removal is quantitative.
planer-milling machines come in two kinds: double-housing and open-side. The double-housing variety has vertical supports on both sides of its long bed; the open-side variety has a vertical support on only one side, allowing the work piece to extend beyond the bed.
MACHINE CONFIGURATIONSurface area of work table:
4 metres * 6 metres.
Maximum distance between the work table & the arm:
Maximum weight of work that the bed can withstand:
SETUP OF WORK PIECE ON THE MACHINE
Lift the work piece, using hoist, to position on machine bed.
Secure work piece in holding fixture, using wrenches, and verify position, using gauges, calipers, or square.
Select cutting tool and mount it in spindle, using hand tools. Adjust controls to set feed rate, speed of cutting tool, and depth of cut.
start machine, and engage automatic feed. Observe operation, stop machine to change cutting tool, and adjust controls.
