Machinability

The term machinability refers to the ease with which a metal can be machined to an acceptable surface finish.Materials with good machinability require little power to cut, can be cut quickly, easily obtain a good finish, and do not wear the tooling much; such materials are said to be free machining. The factors that typically improve a material's performance often degrade its machinability. Therefore, to manufacture components economically, engineers are challenged to find ways to improve machinability without harming performance.

Machinability can be difficult to predict because machining has so many variables. Two sets of factors are the condition of work materials and the physical properties of work materials.

The condition of the work material includes eight factors: microstructure, grain size, heat treatment, chemical composition, fabrication, hardness, yield strength, and tensile strength.

Physical properties are those of the individual material groups, such as the modulus of elasticity, thermal conductivity, thermal expansion, and work hardening

                           Basic Machining Formulas:

ipr = ipt x number of teeth

rpm = 3.82 x sfm / cutting tool diameter

ipm = ipr x rpm

 
SFM Surface Feet per Minute
RPM - Revolutions per Minute
Dia - Diameter of End Mill
IPT - Chipload, Inch per Tooth
IPM Inches per Minute
IPT Inches per Tooth, Chipload
IPR/FR Inch(Feed) per Revolution


  SFM x 3.82 / Dia = RPM
 
  RPM / 3.82 x Dia = SFM

  RPM x IPT x #FL = IPM

  IPM / RPM / #FL = IPT

  IPM / RPM = IPR (Feed Rate)
 
 
MR Metal Removal Cubic Inches per Minute

ADC - Axial Depth of Cut
RDC - Radial Depth of Cut
IPM - Inches per minute ADC x RDC x IPM = MR


HP Horsepower Required IPM - Inches per minute

RDC - Radial Depth of Cut
ADC - Axial Depth of Cut
PC - Power Constants IPM x RDC x ADC x PC = HP

                                 Common Tool Coatings

• Titanium Nitride (TiN)
General purpose PVD coating that increases hardness and has a high oxidation temperature. This coating works great while cutting or forming with HSS tooling.

•Titanium Carbo-Nitride (TiCN)
The addition of carbon adds more hardness and better surface lubricity. This coating is ideal for HSS cutting tools.

 • Titanium Aluminum Nitride (TiAlN or AlTiN)
A formed layer of aluminum oxide gives this tool better life in high heat applications. This coating is primarily selected for carbide tooling where little to no coolant is being used. AlTiN offers a higher surface hardness than that of TiAlN, along with different percentages of aluminum and titanium.
 
• Chromium Nitride (CrN)
The anti-seizure properties of this coating makes it preferred in situations where BUE is common. HSS or carbide cutting and forming tools will be seen with this almost invisible coating.

 • Diamond
A CVD process that offers the highest performance available in non-ferrous materials. Ideal for cutting graphite, MMC (Metal Matrix Composites), high silicon aluminum and many other abrasive materials (Note: True diamond coatings should not be used while machining steels. More heat is generated while cutting steels and thus causes chemical reactions that break down the bonds that hold this coating to the tool).

Schunk-Sino-R
Heavy Duty Milling Chuck





 SINO-R stands for universal application at maximum clamping forces. Developed for heavy-duty cutting, SINO-R is an outstanding alternative to the usual mechanical power chucks.

 SINO-R provides an excellent combination of high radial rigidity and very good damping characteristics.

Keep Bacteria At Bay For A Better Smelling Shop!

Bacteria is the major cause of rancidity and rotten smelling coolant. Considerable time and money can be spent trying to combat these issues. Keeping the bacteria in check makes good economic sense — and good scents!

Where does the bacteria come from?

Rancid coolant from other shops — If parts are received from another shop dirty, grimy, and covered with sticky residue, clean them to avoid contaminating your sumps.
Rancid coolant from sawing operations — Saws are often ignored and the coolant quickly becomes rancid.Operator hygiene and personal habits — The same bacteria that can cause many illnesses can be found in sumps. Operators should refrain from spitting anything into the sump.

Air hoses — Oiled lines harbor and feed bacteria. Blowing off parts, into the machines, adds a nice dose of bacteria on a regular basis.
Old, stinky, or stagnant coolant like that found around chip hoppers should never be added back into the sump.

Dirty, contaminated containers — Containers used for mixing and transporting fresh coolant should always be clean.

Oil smoke and coolant mist collectors that drain back into the sump — The coolant and oils that collect and sit in these units are usually laden with bacteria and should be disposed of.

Cheap rubber hoses — Using cheap rubber for your mixing station will cost you in the long run because they can be breeding ground for bacteria.

Caught early enough through regular laboratory testing, bacteria can be controlled with one of Master Chemical’s tank side adds. Topping off the sump everyday will go a long way towards extending the life of the sump by maintaining the proper concentration and pH.

When it is time to dump your sump and start fresh, use Whamex sump cleaner a few days before the clean out. It will help loosen the grime and clean out the nooks and crannies of your machine.
