Turning (using cycle 95)

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

Tools:

           􀂃 Pos#1: Left Corner Tool, CL-SCLCL – 2020 L 1208
        􀂃 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

(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
