Maydown International Tools Limited was formed in 1961, and is wholly British owned. We haverisen to occupy a prominent position within the United Kingdom in the milling tooling market,

which is largely dominated by multi-national conglomerates.

Based in the Midlands at Tamworth in Staffordshire we stock items manufactured as standards inour extensive milling catalogue. Within the United Kingdom we sell our products directly to the

end user through our field sales force - bringing both quality and keen pricing within the reach oftightly controlled customer budgets. Our products are innovative and have many demonstrableadvantages over the competitors. Our technical sales force is able to conduct tooling surveys,and perform demonstrations on customer machines to prove their adaptability and economy.

Our internal sales office at Tamworth process all the stock orders, withcomputerised links to the stores and production to ensure prompt deliveries of customer

requirements. Orders received for standard items up to 16:30 hours daily, (or later just ask!) willbe despatched the same day.

While Maydown would not claim to have the same financial resources as many of our majormulti-national competitors, we do claim that the very latest high-tech plant and quality controlmethods make our products hard to beat. Due to our relatively low overheads, and speed ofreaction, our tooling can be priced very competitively - as a result we are currently enjoying

healthy growth rates with matching profits.

SECTION AMAYDOWN INDEXABLE END MILLS & FACEMILLS

Page A2Maydown APKT cutters are a range of versatile cutters withthree separate insert geometry's to cope with the demandsof most materials including light alloy steels and stainlesssteel. The APKT insert is also available with different cornerradii. With diameters from 10mm up to 63mm, screwedweldon shanks, plain shanks and using the same insert, allapplications are met.

Super Aludex is Maydown's answer to light alloy machining. The high positive axial and radialrake angles together with maximum swarf clearance, allow for considerable metal removalrates with minimal horse power consumption.Page A13

Page A4Maydown's XL range of indexable end millsand face mills have been designed specificallyto cope with the demands of all materials. Wehave 7 different grades, 4 different cornerradii and 3 distinct insert geometries, makingour XL cutters an excellent choice fromAluminium through cast iron and steels tostainless steel.

The Maydown MINIDEXrange of cutters coversthe need for smallIndexable End Mills.Ranging from 10mm to25mm diameters in threelengths, with bothscrewed and plain shanksall application needs aremet. All sizes take thesame indexable insertsand spares.Page A7

STRESSES ON CUTTING EDGES WHEN MILLINGWhen milling each individual tooth is only in contact with the workpiece for a maximum of 180° per revolution. Consequently certainconditions affect the cutting edges:

A) SUDDEN VARIATIONSThe sudden variation in cutting forces on the insert could lead to small gashes on the cutting edges.

B) THERMAL EFFECTTemperatures of up to 1,000° can develop when the cutting edge enters the workpiece.The thermal effects alter as the cut progresses, this combined with the effect of the insert beingexposed to the air or coolant (in the non-cutting position) could lead to cracks appearing along thecutting edge.

C) BREAKOUTSBreakout or chipping develops through overworking the insert.REMEDY*check cutting edge condition*check facets and/or radius*use a tougher grade

D) WEAR DOWN THE CLEARANCE FACENormal condition when milling for a period of time.REMEDY*increase feed*use a more wear resistant grade*lower cutting speed

E) PLASTIC DEFORMATIONHigh cutting temperatures can lead to this condition.REMEDY*reduce cutting speed*use a grade which is more resistant to this condition

F) SPLINTERINGChange in temperatures and intermittent cutting can lead to splintering of the cutting edge.REMEDY*alter cutting data, reduce load*use a tougher grade carbide*adjust entry and exit conditions

G) CRATERINGCratering in general is not a reason for short tool life.REMEDY*reduce cutting speed*use a more wear resistant grade

H) BUILT UP EDGESThis condition occurs when a cutting speed is too low.REMEDY*alter cutting data (increase)*alter geometry, positive cutting angle

MAYDOWN FORMULAE FOR MILLING CALCULATIONSKey for formulae:

D = Diameter of cutter T = Number of teeth rpm = Revolutions per minute F = Cutter feed (or table traverse) FT = Feed per tooth S = Peripheral speed of cutter π = 3.1416 HP = Motor horsepower C= Machinability constant

TO CALCULATE CUTTER SPEED

S (ft / min) = D x π x rpm

= 0.2618 D x rpm12

S (m / min) = D x π x rpm

1000

TO CALCULATE FEED PER TOOTH

FT = F

T x rpm

TO CALCULATE CUTTER REVOLUTION

rpm = S (ft / min)

orS (m / min) x 1000

0.2618 D D x π

TO CALCULATE CUTTER FEED (TABLE TRAVERSE)

F = FT x T x rpm

HORSEPOWER HP

Power requirements:

Horsepower required can be calculated using the following formula which is based on a metal removal rate of one cubic inch perminute per horsepower.The machinability constant 'C' allows 25% for cutter dulling and 60% power efficiency at the cutter spindle.

HP = Depth of cut x width of cut x T x FT x rpm

=Depth of cut x width of cut x F

C C

Kilowatts = HP x 1.34

Machinability Constant 'C' = Aluminium and soft alloys = 4.0, Grey cast iron = 1.5, Steel up to 300 HB = 0.6, Steel up to400HB = 0.5, Brass (duplex) = 2.5, Low Carbon steel = 1.0, Bronze = 2.0

TO CALCULATE AVERAGE CHIP THICKNESS

= Feed per tooth x √cutting width

cutting diameter

TO CALCULATE METAL REMOVAL (cubic)

= Feed x depth of cut x width of cut

RPM = Vc x 1000 Table Feed = RPM x fz x Number of teeth

Dia x π

Note: Feed rate should be reduced by around 50% of Long Series cutters

For: To Relieve:Harder materials - lower speed and feed rateEasily machined materials - raise speed and feed rateImproving finish - raise speed, lower feedAbrasive materials - lower speed, raise feed

"Chatter" - increase feed rateFrail set-up - raise speed, lower feedExcessive edge wear - reduce speed, raise feedExcessive edge chipping - raise speed, lower feed.

Solid carbide cutters have hardness approaching twice that of High Speed Steel, and the mechanical properties produce rigidityvirtually without deflection under bending stress. Machine tools and fixtures should be robust, rigid and free of 'play'. Speeds andfeeds should be selected with care and adjusted as found expedient for each particular job.
