Dc 20 mm, vc = 200 m/min, n = 3184 rpm, fn = 0.20 mm/r, hole depth = 50 mm. TL (meters): 15 meters. TL (No. of holes): 15 x 1000/50 = 300 holes. TL (min): 15 x 1000/ vf = 15 x 1000/ ( fn x n) = 15 x 1000 / (0.20 x 3184) = 23 min. The most common tool life criteria in drilling is flank wear. Tool life is dependent on:

Typical values for feed rate in several conventional machining operations are provided below. Feed rate in straight turning—0.01 – 0.1mm/rev for finishing cut; 0.05 – 0.5mm/rev for rough cut. Feed rate in thread turning—Equals to the pitch or lead (for multi-start threads) of thread (usually 0.5 or 1.0mm/rev).

Plasma cutting machine is a new type of hot cutting equipment, its working principle is based on the compressed air as working gas, high temperature and high speed of plasma arc as heat source, molten metal will be partially melted, and at the same time high-speed air blow away the molten metal, and form the narrow cut seam.

These products are suitable to cut different material such as iron, steel, mild steel and many others. Portable Gas Cutting Machines provides 40% Higher Productivity than Conventional Machine. They are quality tested on varied parameters before delivery to the customers.

The Cutting Speed Formula may be simple once you have all the parameters, but finding the proper values for the parameters is a lot harder than it looks. I know many of you are leaning forward about now and thinking something like, “Now Bob, it’s just not that hard to look up the manufacturer’s recommendations for the cutter.”

This formula is used to calculate the machining time from the drilling depth, the number of holes, the spindle feed, and the feed per revolution. Example of drilling into SCM430 steel: Drilling depth (ld) = 35 mm. Number of holes (i) = 1. Spindle speed (n) = 1500 min -1. Feed per revolution (fr) = 0.1 mm/rev.

Q. 2 Find out the inch meter for 20 m pipeline of 2" size. Ans: Inch meter = Pipe size in inches x length in m. = 2" x 20 = 40 inch meter. Note : Inch meter will be more relevant in case of yard piping whereas inch dia will be more relevant in case of plant piping. 6.

Isolated from these effects, the operator naturally maintains speed, taking full advantage of available horsepower. The result: More acres per hour and more money in your pocket. Try out our mowing productivity calculator below or reference our handy mowing productivity chart to determine just how productive you can be in a few hours or in a ...

Reduced feed per tooth: in. (chip load at the cut) mm (no productivity formula) F p Feed rate: (IPM) (with productivity formula) mm/min (with productivity formula) Q p Metal removal rate: (MRR) (no productivity formula) cm3/min (no productivity formula)

Sep 19, 2016 · Formula to calculate machine productivity: Machine productivity = (Number of total garments produced / Total stitching machines used) Productivity is the ratio of output and input of a process in a defined time frame. Divide garment output of a line by machine input. In the readymade garment production, factories measure productivity majorly as labour productivity and machine productivity.

The processes of cutting steel consist of the following reaction: 3Fe + 2O 2 → Fe 3 O 4 + heat (27,000 cal.) The successfulness of gas cutting process depends upon two factors:
