Machine tools machinability and calculations

Machining is achieved by knowing the machine parts, feed rates and the proper speeds based on the rigidity of the workpiece as well as cutting tool. Turning process works to remove material from the rotating workpiece surface and reducing its diameter for each spindle revolution or rpm, this operation could be taper turning, form turning, and contour turning, drilling, knurling, threading or boring.

Spindle speed is calculated as rpm= (CS*320)/D where rpm represents revolutions per minute of the cutter or workpiece, CS=cutting speed, D=diameter

Feed rate is the multiplication of calculated speed, number of teeth of the cutter and chip load(feed per tooth).

Feed per tooth=feed/(spindle speed*number of flutes)
Straight cut depth when cutting threads on the lathe=0.6134*pitch

Range of feed per revolution for roughing on a lathe machine:

Work material	High speed steel		carbide
	Inches	millimetres	inches	millimetres
Mild steel	0.010-0.020	0.25-0.5	0.015-0.035	0.4-0.9
Tool steel	0.010-0.020	0.25-0.5	0.015-0.035	0.25-09
Cast iron	0.015-0.025	0.4-0.65	0.015-0.030	0.4-0.75
aluminum	0.015-0.030	0.4-0.75	0.015-0.035	0.4-0.9
brass	0.015-0.025	0.4-0.65	0.015-0.030	0.4-0.75

Other operations are:

About boring machining, cutting is performed inside the material either horizontal or vertical.

Milling machine allows work part to be fed past a rotating tool with edges.

Further, hacksaw machine is used for linear reciprocating motion while bandsaw helps with linear continuous motion.

Finishing improves the product appearance could be done with filing.

Knurling helps to form ridges increasing the diameter of the workpiece unto 0.030 inch and this process should be performed with high feed rate and at low spindle speed.

Grinding produces required sizes with fine finishing.

Basic comparison between Stainless steel and carbon steel metals

Stainless steel alloy with a base 10.5% chromium content by weight is an outstanding metal for its erosion resistance property, and it is broadly used for sustenance taking care of and cutlery among numerous different applications. Stainless steel does not promptly corrode, rust or stain with water as customary steel does. Notwithstanding, it is not completely stain proof in low-oxygen, high-saltiness, or poor air-flow situations. There are different evaluations and surface compositions of stainless steel to suit the environment the combination must persevere. Stainless steel is utilized where both the attributes of steel and consumption resistance are required.

Stainless steel contrasts from carbon steel by the measure of chromium substance. Carbon steel is made out of iron and carbon level shifts between 0.12 – 2.1%. The 300 arrangement of stainless steel evaluations is unaffected by any of the frail bases, for example, ammonium hydroxide, even in high concentrations and at high temperatures. High oxidation resistance in air at surrounding temperature is commonly accomplished with expansion of at least 13% (by mass) chromium, and up to 26% is used for harsh situations. Also, stainless steel is non-brittle and milder however carbon steel is fragile and in addition hard and wear-safe. Be that as it may subject to a destructive domain, stainless steel may really be the best choice with superior mechanical chemical composition of materials for some fields, for example, in structures, landmarks, car, and machinery and so on.

To conclude, the group of stainless steels incorporates materials that are hard and delicate, solid and powerless, adaptable and unbending, and cost focused and amazingly costly. So does the series of carbon steels. Rather, you have to opt for in the view of the individual plan criteria required by every area of its usage.

How to replace a Miter Saw Blade quickly with safety?

The substitution of the miter saw blade is an occasionally tool safeguarding process.In fact, it is a easy and effortless act only requiring a couple of tools as an Allen wrench, a screw driver, possibly a piece of scrap wood.  The change of the miter saw blade first involve a number of common safety measures. The saw needs to be turned off and unplugged the equipment from the socket. Before operating on any power tool, make sure that it is not viable for the tool to turn on. As it is always risky to secure a blade, just remain alerted on the job that needs to be finished.

First, the blade guard has to be removed, so fully pull up the guard to achieve access to the screw holding the miter saw to the guard and unscrew it. Leave go of the screw to slide further backward the blade guard. Point it around 170 degrees at the back compared to its original position, revealing thus the blade bolt and spindle lock of the miter saw.  Press down the locking pin of the saw and rotate the blade till it is locked properly. Next remove the blade bolt with an Allen wrench to loosen it. In most cases, the blade bolt is turned clockwise, but that is not always the case. So, attempt to locate a sign on the tool for the accurate direction to lose the bolt or just test the saws with your finger in advance. Take away the flange and change the blade with the new blade. Change the flange along with the blade bolt, double checking that you have securely tightened the bolt with the allen wrench but not overly. Glide forward the blade guard and fasten the screw very well which keeps it to the miter saw equipment in place. Put back the guard to its usual position using a screwdriver and reengage the tool. Check the right working order of the miter saw by producing cuts to make sure the cutting as clean and even. It is quick and simple to replace a miter saw blade, but it should be done with care and by taking clearer safety instructions. It is significant to always have a well maintained and pointed blade as it is considerably improve your work grades along with your safety.
