HEAVY METALS VOCABULARY

Across
A MEASUREMENT IN ONE DIRECTION; ONE OF THREEE COORDINATES-LENGTH, WIDTH & DEPTH. THICKNESS, RADIUS AND DIAMETER ARE ALSO GIVEN AS DIMENSIONS ON A BLUEPRINT.
ANY PROCESS SUCH AS ROLLING, FORGING OR FORMING A COLD METAL IN WHICH THE METAL IS STRESSED BEYOND ITS YIELD POINT. THE GRAINS OF THE METAL ARE DEFORMED IN THE PROCESS CAUSING THE METAL TO HAVE A HIGHER HARDNESS AND LOWER DUCTILITY.
A TERM REFERRING TO ANY OF SEVERAL MATERIALS USED AS A COOLANT WHEN MACHINING METAL.
THE ENLARGEMENT OF A MATERIAL USUALLY CAUSED BY AN INCREASE IN TEMPERATURE.
A COMBINATION OF 2 OR MORE SUBSTANCE, ESPECIALLY METALS WHEN ASSOCIATED WITH CUTTING TOOLS, WHICH GIVE SPECIFIC CHARACTERISTICS TO THE RESULTING CUTTING TOOL MATERIAL.
THE CHECKING OR CRACKING OF A CUTTING TOOL CAUSED BY EXCESSIVE HEAT.
REVOLUTIONS PER MINUTE. IN REFERENCE TO MACHINING METALS, THE NUMBER OF REVOLUTIONS THE WORK OR THE CUTTING TOOL TURNS IN ONE MINUTE.
: A CUTTING TOOL ANGLE THAT PRODUCES KEENNESS TO THE CUTTING EDGES. (TOP)
THE COLD WELDING OF TWO METAL SURFACES IN INTIMATE CONTACT UNDER PRESSURE. ALSO CALLED SEIZING, IT IS MORE SEVERE AND MORE LIKELY TO HAPPEN BETWEEN SIMILAR SOFT METALS, ESPECIALLY HWEN THEY ARE CLEAN AND DRY.
A CONCENTRATION OF FORCES IN WHICH THE BENDING MOVEMENT IS VIRTUALLY ZERO AND THE METAL TENDS TO TEAR OR BE CUT ALONG A TRANSVERSAL AXIS AT THE POINT OF APPLIED PRESSURE.
THE ANGLE THAT PROVIDES CUTTING EDGE CLEARANCE ON A SIDE POINT CUTTING TOOL. (SIDE)
THE OXIDE FORMED ON THE SURFACE OF A METAL THAT HAS BEEN HELD AT HIGH TEMPERATURE IN AIR.
Down
THE RELATIVE EASE OF MACHINING, WHICH IS RELATED TO THE HARDNESS OF THE MATERIAL TO BE CUT.
IN REFERENCE TO A SINGLE POINT CUTTING TOOL IT DESCRIBES NEITHER POSITIVE OR NEGATIVE RAKE ON A CUTTING SURFACE OF THE TOOL. ZERO RAKE ANGLE.
AN EXTEREMELY HARD COMPOUND OF TUNGSTEN AND CARBON. USED FOR CUTTING TOOLS BY MIXING TUNGSTEN CARBIDE WITH COBALT IN A POWDER FORM AND THEN FORMING BRIQUETTES UNDER PRESSURE WHICH ARE THEN SINTERED AT HIGH TEMPERATURE TO FORM A CUTTING TOOL.
A FLUID, LIQUID OR GAS USED TO COOL THE CUTTING TOOL AND WORK DURING A MACHINING OPERATION.
:THE PROPERTY OF A MATERIAL THAT CAUSES IT TO SUDDENLY BREAT AT A GIVEN STRESS WITHOUT BENDING OR DISTORTING. GLASS, CERAMICS AND CAST IRON ARE SOMEWHAT BRITTLE MATERIALS.
ALSO CALLED CEMENITE (FeC). A COMPOUND OF (4) IRON AND (1) CARBON WHCH IS QUITE HARD.
IRON. FROM THE LATIN WORD FERRUM, MEAING IRON. ANY ALLOY CONTAINING A SIGNIFICANT AMOUNT OF IRON.
VIBRATION OF THE WORK, MACHINE OR CUTTING TOOL OR A COMBINATION OF ALL THREE DUE TO LOOSENESS OR A WEAKNESS IN ONE OR MORE OF THESE AREAS.
REFERS TO THE RADIUS ON THE NOSE OR CUTTING POINT ON A SINGLE POINT CUTTING TOOL. IN GENERAL, A LARGER NOSE RADIUS PRODUCES A BETTER FINISH AND IS STRONGER THAN A SMALLER NOSE RADIUS.
THE MATERIAL THAT IS REMOVED WHEN METAL IS CUT. APPEAREANCE OF CHIPS WILL VARY DUE TO THE TYPE OF MATERIAL BEING CUT, TYPE OF MACHINING OPERATION AND TYPE & CONDITION OF THE CUTTING TOOL.
THE PROPERTY OF A METAL TO BE DEFORMED PERMANENTALY WITHOUT RUPTURE WHILE UNDER TENSION.
SURFACE FEET PER MINUTE. THE DISTANCE IN FEET A CUTTING TOOL TRAVELS IN CUT IN ONE MINUTE.
