Create an NC Program to produce the finished workpiece shown in the drawing above using cycle 95. It is needed to make a 1 mm facing operation prior to taper turning; all dimensions are in mm.
Parameters:
o Chuck type: outside.
o Chucking depth: 15 mm
o Material: Aluminum Almg1
o Zero point: right work part side
o Chucking depth: 15 mm
o Material: Aluminum Almg1
o Zero point: right work part side
Tools:
Pos#1: Left Corner Tool, CL-SCLCL – 2020 L 1208
Pos#2: Left Corner Tool, CL-SVJCL – 2020 L 1604
Pos#2: Left Corner Tool, CL-SVJCL – 2020 L 1604
o Max. spindle speed limit: 2000 RPM
o Constant cutting speed: 200 m/min
o Feed rate: 0.3 mm/rev
o Spindle rotation: counter clockwise
o Constant cutting speed: 200 m/min
o Feed rate: 0.3 mm/rev
o Spindle rotation: counter clockwise
(Q1) The original length of the workpiece is............., and why?
(Q2) The facing is the first part of the program is:
N05 G54......................what does it mean?
..................................................................................
N10 G92 S2000......................what does it mean?
...................................................................................
N20 G96 S200 F0.3 M4......................what does it mean?
....................................................................................
N25 T1 D1 M6......................what does it mean?
....................................................................................
N30 G0 X42 Z0......................what does it mean?
..................................................................................
Now complete the program to do the facing only:
N 35 ........................................................
N 40 ........................................................
N 45 ........................................................
N 50 .........................................................
N 55 .........................................................
N 60 T2 D1 M6......................what does it mean?
.................................................................................
Now you can complete the program to do the final shape as following:
N60 G0 X42 Z2
N65 CYCLE95 ("L1205",2,0,0,0,0.2,0.1,0.1,1)
...........................................(thr subprogram L1205 will start here)
N 20 ...................................
N 25....................................
N 30....................................
N 40....................................
N 45 M17.....what dos it mean?
N70 G0 X150 Z150
N80 M30
