A drilling operation is to be carried out with a 12.7mm diameter twist drill in a steel work part.The hole is a blind hole of 50mm depth. The cutting speed is 25mm/min and the feed is 0.3mm/rev Determine the following i)Cutting time to complete the driling ii)Metal removal rate
A 78 mm thick plate is to be milled down to a thickness of 60 mm using an 80 mm face milling cutter. Calculate the processing time if the cutting depth is 6 mm, the feed/rev is 1.1 mm and the cutting speed is 15 m/min, and if the over run for a 620 mm long plate is 10 mm.
Find the machining time required to turn a mild steel rod from 65mm to 58 mm over a length of 100 mm by using a carbide insert. If the approach length and over run length is taken as 5 mm, Cutting speed as 20 m/min and feed is =0.2 mm/rev, and the depth of cut is 0.5mm
A flat milling operation will be carried out with a horizontal milling machine, in a piece of 250 mm in length and 50 mm in width, using a felicoidal bur with a diameter of 75 mm, with 10 teeth. If the feed per tooth is 0.2mm, and the cutting speed is 0.75 m / s, how would you determine the speed of metal removal to remove 6 mm from the surface of this piece?
In orthogonal turning of a low carbon steel bar of diameter 150 mm with uncoated carbide tool. the cutting velocity is 90 m/min The feed is 0.24 mm/rev and the depth of cut is 2 mm. The chip thickness obtained is 0.48 mm If the orthogonal rake angle is zero and the principal cutting edge angle is 90° Calculate the shear angle in degree.
Calculate the machining time required for making 60 holes on an MS plate of 80 mm thickness with a drillbit of diameter 20 mm with a cutting speed V= 40 m/min, the feed f = 0.2 mm/rev. (Assume approach length,A and over run O as 2mm and point angle as 110o). Calculate material removal rate.
Note: Read the question carefully and give me right solutions according to the question. In orthogonal cutting of steel tube of 150 mm diameter and 2 mm thick, the cutting force was 130 kg and feed force was 35 kg for chip thickness of 0.3mm. The orthogonal cut was taken at 60 meter per minute with a feed of 0.14 mm/rev. If the back rack angle of the cutting tool was - 8 o (minus 8 degree), then calculate the shear strain and strain energy per unit volume.
The cutting speed in in/min of a 12 mm drill operating at 600 rpm is nearly equal to
A two-spindle drill cuts two holes at the same time, one 1/2 inch and one 3/4 inch. The workpiece is 1.0 inches thick. Both drills have point angles of 118 degrees and the cutting speed for the material is 300 ft/min. The rotational speed of each drill can be set individually but the feed rate for both holes must be set to the same value because they move together into the material. The feed rate is set so that the total metal removal rate of both drills combined does not exceed 1.50 in3/min. Determine (a) maximum feed rate (in/min) that can be used, (b) individual feeds (in/rev) for each hole, and (c) cutting time for the operation.
In a turning operation, the operator has established that a single pass on the cylindrical workpiece must be completed in 5.0 min. The piece is 400 mm long and 150 mm in diameter. Using a feed of 0.30 mm / rev and a depth of cut of 4.0 mm, what speed of cut should be used to meet this machining time?
A mild steel block of width 40 mm is being milled using a straight slab cutter 70 mm diameter with 30 teeth. If the cutter rotates at 40 rpm, and depth of cut is 2 mm, what is the value of maximum uncut chip thickness when the table feed is 20 mm/min?
Calculate the time required for completing a 5mm deep finishing cut on a 150mm wide, 600mmlong face of a 25mm thick steel block using a face milling cutter of 150mm diameter with 6teeth. The cutting condition are Vc =1.5m/sec and fz = 0.1mm.
