You will gain experience in additional geometry selection (Chaining) techniques that will allow you to cut most Contour shapesyou come across. The toolpaths will consist of several new types of contours.Overview of Exercise:In this lesson we will machine the part shown by first Facing the 5.0 X 8.0 stock, then machining the yellowareas shown by using several different types of 2D contour toolpaths and tools.NEW CONCEPTS COVERED IN THIS LESSON:ξξξξξξξFacing rough stockMulti pass contour to cut an open pocket shapeRemoving excess stockChamfer contour toolpathMultiple techniques for contour chain selectionChain Manager optionsReview of basic Mastercam for SolidWorks general workflow proceduresContour Toolpaths —Part 2 Lesson 3 Page 3—1 Mastercam for SolidWorks Step by Step Programming ExercisesContour Toolpaths —Part 2 Lesson 3 Page 3—2 Mastercam for SolidWorks Step by Step Programming ExercisesContour Toolpaths Additional Reference Information:REFERENCE INFORMATION:2D GEOMETRY SELECTION OPTIONSSingle Edge: Click the edge.(The Mastercam Chain Manager gives the option toautomatically propogate along tangencies.)Multiple Edges: CTRL-Click each edge.(The Chain Manager will display all individual edges.The CHAINS tab will show how Mastercam hasconnected continuous edges into a single Chain.)Select Tangency: Right Click on Edge and choosethe option from the menu.(This will select all of the edges tangent to the onehighlighted and put them in the Selection list in theChain Manager.)Contour Toolpaths —Part 2 Lesson 3 Page 3—3 Mastercam for SolidWorks Step by Step Programming ExercisesSelect Loop: Right Click on Edge and choose theoption from the menu.(This will select every connecting edge on a face,whether tangent or not. If the wrong Loop is chosenby SolidWorks, click the yellow arrow to toggle to theother option.)Partial Loop: Click the first entity, then CTRL-RIGHTClick on the second entity to choose the option fromthe menu. NOTE: When CTRL-RIGHT Clicking onthe second entity, you must select on the end of theentity nearest the direction you want to close. Formore information, see the SolidWorks Help menu.(This will allow a faster method of selecting a largenumber of individual edges on complicated contours.)Select Face: Click on a Face.(This will select every individual edge on a face,including interior edges, whether tangent or not. TheChain Manager gives the option to use only outer loopon faces. This is useful if you only want to cut theouter shape.)Contour Toolpaths —Part 2 Lesson 3 Page 3—4 Mastercam for SolidWorks Step by Step Programming ExercisesCONTOUR TOOLPATHS PART 2 TUTORIALProcess Step 1: Prepare and Orient Model forMachiningIn this task you will choose the view to machine fromand locate part on the machine. Due to the shape ofthe model, there is no good location for the origin. Wewill use SolidWorks to create the origin location first.1. Open the part “CONTOUR 2.SLDPRT”2. From the SolidWorks Drop Down View Menu, makesure View Sketches is selected.(We will need to see Sketches in a later step.)3. Select this face and select Insert Sketch from thepop up icons or from the SolidWorks Insert menu.(This will start a new sketch on this top face. Thefollowing steps will have us create a single point atthe theoretical sharp corner of the stock. So we canlocate the machining origin where we want it.)Contour Toolpaths —Part 2 Lesson 3 Page 3—5 Mastercam for SolidWorks Step by Step Programming Exercises4. Rotate the model similar to the view shown andselect both of the edges by pressing the Control keyand selecting these two edges.5. Select the Point icon from the SolidWorks Sketchtoolbar or from the drop down menu Tools – SketchEntities – Point, to create a point entity at theintersection of the two lines.(Note: You must select the (2) edges first to getthe point at the intersection.)6. Exit the Sketch.(Right Mouse Click and Select Icon.)Contour Toolpaths —Part 2 Lesson 3 Page 3—6 Mastercam for SolidWorks Step by Step Programming Exercises7. From the Mastercam drop down menu, selectView Manager.8. View Manager Dialog settings:9. Select the Geometry button.10. Rotate the model as needed so you can pick the topSolid Face to be the Machine View.11. Rotate XY as desired for Direction.(We will leave at 0° in this example.)12. Click OK to accept.13. Give the new view a Name.(“2D Machining View” in this example.)Contour Toolpaths —Part 2 Lesson 3 Page 3—7 Mastercam for SolidWorks Step by Step Programming Exercises14. Set the Current View and Origin equal to this newview by clicking the “EQUALS” button.15. Select button to choose the desired Origin Point.16. Select the sketch point previously createdas shown.(In order to see this sketch Point,View Sketches must be on. See Step # 2)17. Click OK to accept.18. Click OK to Accept again to exit and save the ViewManager settings dialog.(The Mastercam Origin should be located on thepoint entity as shown.)Contour Toolpaths —Part 2 Lesson 3 Page 3—8 .
