Description This course is designed to enable the programmer to use the control’s powerful Macro programming feature on milling machines Students will lean to read and write repetitive machining cycle Will understand the components of the macro body and the meaning of the macro call command like G65, G66 and G67 2

Back to basic = Speed & Feed The consideration for determining speeds and feed are changing The charts provided are based on actual machining experience utilizing cutting techniques

Spee =

V * 318 Dia

or

V * 1000 Dia * π

( 3.1412 )

End Feed = Speed * no of tooth * Feed per tooth Drill Feed = Speed * Feed per Revolution Tap Feed = Speed * Pitch 4

Chip Thickness Feed per tooth

Diameter of cutter

Chip Thickness depend on Ad = depth of cut, Rd = width of cut, Sz = feed per tooth

Depth of cut Chip Thickness 5

Feed Per Tooth & Feed Per Revolution

Calculation of Speed & Feed If Ball nose

Cutting speed Feed per tooth Answer is Speed

= 10 mm ( 2 teeth ) = 200 m/min ( V ) = 0.1 mm ( Sz ) = 200 * 318 / 10

= 6360 ( rpm ) Feed = 6360 * 2 * 0.1 = 1272 mm/min if feed reduce to 50% mean F636, Sz = 0.05 7

Arithmetic Expression Answer

if #1 = 8. # [ #1 ]

if #1 = 10. # [ 100 + #1 ] = 123.

#110

#100 = #133 + #110

#100
