64By Contour: If is selected one contour will bemilled from start to finish, before the nextcontour is worked upon.Lead in/out parameters describe the way thetool will approach the contour at the start/endof the roughing, and for each finish pass.The use of lead in/out is optional when thecompensation is set to computer or none. It ishowever mandatory, when any compensationis performed by the controller.Use Lead In/Out Parameters:Enables or disables the lead in and out.Use Line:Enable or disables the lead in/out lines.Line Length:Is the length of the lead in/out line.Perpendicular: If it is selected the line willbe perpendicular to the following element forlead in, and the previous element for lead out.Parallel: If it is selected the line will beparallel to the following element for lead in,and the previous element for lead out.Use Arc:Enables/disables the lead in/out arcs.Radius: The radius of the lead in/out arc.Sweep: Sweep angle of the lead in/out arc.The two arrows in the middle of the dialogare used to copy all values from lead in to out,and the other way.
65Now close the parameters dialog with OK and click on Export Clipboard. The NCoperation is now in the clipboard, and it is ready for insertion.Change the window to the NC program, and move to the very end, by pressing Ctrl-End.Insert the text from the clipboard, either by pressing Ctrl-v, or selecting Edit → Paste fromthe drop down menu.The NC program in the Editor now consists of two operations and currently they are bothmade with the same tool. Now we need to insert a new tool for the contour operatio14.2. Inserting a Tool with Feed and Speed CalculatorFollow the steps from the previous tutorial for the Feed and Speed. Instead of the values usedthere, use the following values:Tool # : 2Diameter (D) in mm : 10# Flutes (Z) : 4Feed per tooth (Sz) in mm : 0.06Cutting Speed (V) in mm/min : 175Now the last two values have been calculated andinserted in the dialog. They should be:RPM : 5570Feedrate (F) in mm/min : 1336.9015Correct the RPM to 5500 and thenFeedrate (F) in mm/min: to 1320.Now the Feed and Speed dialog should look like theone to the right:
