Using Arc dialog. Once complete. The arcs represent drilled holes 6. It is obviously easier to make the modifications to the part while working in the new CPL rather than in one of the existing CPLs. Section I1 Page 16 Version 3. An unlimited number of CPLs can be created. The diagram below shows the orientation of a simple part within the World co-ordinate system.
As each CPL has its own x. To help you construct a model. A construction plane defines a local co-ordinate system at any orientation to the World axes. The diagram below shows the name of each system CPL. EdgeCAMs Preferences command. EdgeCAM will allow you to set a datum in the centre of a cylinder.
There are two methods of defining a CPL using a solid face. The default setting for this option is ON. Section I1 Page 18 Version 3. For both options you are given the opportunity to specify the origin for the new CPL. You can either select a planar face. When a cylindrical face is selected. You are also given the opportunity to define an origin for the new CPL. Section I1 Page 20 Version 3. The part is a solid model and represents the Fixturing devise. If you need to change the position of a CPL.
You can pick either a vertex. If the model is modified. Two further solid models will be used in this exercise. In order for the Simulator to properly represent the working environment. How will this feature be used during the Manufacturing Sequence? Section I1 Page 22 Version 3. The next stage is to insert the solid body which represents the component. Upon inspection. The Z Axis must be perpendicular to each Feature.
Note that the three countersunk holes are not flat to the face. To enhance the representation of the CPL axes. In this instance. Check the previous diagram to ascertain if the axes are running in the correct direction.
Ensure that Contour Pocket and 3D Pocket are activated. If you have had the opportunity to inspect the Solid model. You do not need to find Milled features. In this instance you will observe that the singular pocket has a draft angle. Once the CPL is established. Because this part file has multiple solids.
Can you explain why Feature Finder has not recognised the thread detail? Check that the feature has been acknowledged in the Features window. Inspect the counter-bore features. The final face — Face C — is slightly more challenging.
You should detect 3 counterbored holes. It is a common mistake not to check such details and assume that the feature is square. To utilise this feature.
As with all aspects of EdgeCAM. Although the standard CPLs have their origins coincident with the World origin. A name.
There are two methods of orientating a CPL. An orientation. Section I1 Page 28 Version 3. Although the standard CPLs are orthogonal to the World axes.
A CPL definition requires three main parameters: An origin. If the Origin check box has not been selected the CPL origin is at the first position. If the Origin check box has not been selected the CPL origin is at the end of the line nearest to the entity digitise. The direction of the positive Z-axis is established by the right hand rule. The X-axis is defined by the line between the first and second positions. Normal to line.
Y and Z axis. Define by arc. Through 3 points. The third position determines on which side of the X-axis the positive Y-axis lies. There are five methods of construction plane definition. If the Origin check box has not been selected the CPL origin is at the centre of the arc. Allows you to select conical and cylindrical faces from a solid for CPL creation. Section I1 Page 30 Version 3. Select a Solid Face Face Axis.
Any rotation or change of origin will be applied to a copy of the current CPL If the Name modifier is left blank. Rotation angles supplied through the Rotation modifier are incremental from the selected reference. Reference This modifier is used to select an existing CPL or view port that is used as a reference from which a new CPL is constructed.
Available in Solid Machinist Licence.
Both methods are mutually exclusive. The following designs need to be positioned on each individual face. Before you create the geometry on must create a CPL. The aim of the exercise is to create simple design geometry of each face.
Position this shape at X0 Y0 Z0. Section I1 Page 32 Version 3. Create a Pentagon Geometry Menu with the following parameters. You will learn how to create a datum CPL on each face and therein. This component is to be loaded to a centring spigot. Section I1 Page 34 Version 3. Note the position of the CPL marker — furthermore.
The physical position of this new CPL is in the centre of the component. Use co-ordinates to position the slots. Using the Slot command Geometry Menu draw three slots. Section I1 Page 36 Version 3. Class Exercise 4 — Creating Tabbed Views 1. To change view ports. This is useful when machining complicated parts as specific views can be quickly restored once they have been saved. LH click over the blue view port selection band situated at the bottom LH corner of the active view. In order to yield multiple views On the Configure View dialog box.
LH clicking this tab will select this view. Observe that there is now a tabbed view created with the same name. Section I1 Page 38 Version 3. Create another new view. Using the drop down menu on the main tool bar. The tabbed view locks the orientation of the part so it cannot be accidentally changed. Select the Default view and the part can then be rotated as normal.
This time set the name and parameters as follows: Observe that the view now updates and tracks the active CPL. You have the ability to Pan and Zoom the part when a tabbed view is selected. This stores the initial view configuration so you can easily switch from the user defined tab to the default tab.
Section I1 Page 40 Version 3. This will allow you to easily navigate around complex parts when creating machining instructions. The following series of exercises will demonstrate how this is accomplished. Editing and Deleting Tabs A mouse click while the cursor is over the view caption will activate the caption menu which includes the menu entries Update and Delete: These properties are specific to each individual tabbed view.
Section I1 Page 42 Version 3. Notice that these views represent the index position for each side of the component. With the components now visible. Class Exercise 5 —Clipped Views 1. The use of clipping makes the view port clearer to work with as unwanted geometry is removed from the view by making it invisible. View clipping is a useful tool for users who work with wire frame components that are mounted and machined in a tombstone scenario.
The part should be displayed as shown herewith. Activate the various tabbed views — each view is specific to each CPL. Save the part as Completed Tombstone Set Up. The view has now been clipped negative down the Z-axis. Experiment with view clipping using the remaining view ports.
This will clip any geometry that lies negative from the Z-level of in the current CPL 9. Edit the properties of view port BO again. Observe the screen. On the Clipping tab. Section I1 Page 44 Version 3. Edit the properties of the tracker view port and observe the settings. Clipping has been activated. Select OK to dismiss the dialog box 4. Observe that the view has updated. From the main tool bar.
The Select to hide option allows you to select an entity on the layer you wish to hide. By default. Layers can be further manipulated from the Properties tab of the Tabbed View. You will then be prompted to digitize entities on the layer to exclude. Check the Override box to override the settings in the Layer Browser. The Layers tab of the Properties dialog contains a duplicate of the layer list in the Layer Browser although the visibility status of layers may differ. Check the Select to hide box and press OK.
Section I1 Page 46 Version 3. Familiarise yourself with the Layers and Features browser. The purpose of the exercise is to create tabbed views. Sometimes this is either not possible or. Section I1 Page 48 Version 3. A more safer and accurate method is to digitise the existing design entities in order to create the CPL. Create the following shape. Create a CPL with the following settings: One would have to calculate the angle of displacement in order to successfully create a CPL.
Rather than calculate an angle which might ultimately be miscalculated and thus the CPL would be wrong we will create the CPL by selecting entities from the model.
By default the CPL will be position at the intersection of the digitise entities. Section I1 Page 50 Version 3. Refer to the diagram below in order to establish the CPL 7.
Create a single line that represents a vertical centre-line on each face of the component. This line will act as a construction line. Referring to previous exercises. Create a 30mm X 45mm rectangle with 5mm corners rads. The slot is position on the horizontal centre-line and must be 1mm offset from the sidewalls.
Enhanced Mouse Controls This exercise will allow you to practice manipulation of components in the screen area 1. Exercise 8. To cancel the point zooming or rotation. Rotating about a Point To rotate the model about a point.
Practice using the enhanced view commands by zooming and rotating around a fixed position. Section I1 Page 54 Version 3. The cursor position will be moved to the centre of the screen and zooming will occur at that point.
This file contains a Turned component. Pick a point on the model and move the wheel forward to Zoom In and backward to Zoom Out while holding down the Ctrl key. Zooming to a Point You can use the mouse wheel to zoom relative to the current cursor position in the active view. The selected point is moved to the screen centre. Component File menu command. The layers will be renamed. You can use this command to insert geometric entities and.
You have control over how much of the named part you want to insert. The dialog offers the following parameters: Segregate Layers — Check this option if you want each component's entities to remain on their separate layers. Select the Insert. Select from Digitise or a list of available CPLs in the current environment. Allows you to specify a prefix to be used to identify CPLs. Insert Sequences — Check this option if you want to insert all machining sequences from the source part.
CPL or sequence name. Duplicates will continue to be distinguished by the addition of '. This is also referred to as Tombstone machining. Please note that the Undo functionality is not supported when inserting components with sequences. Section I1 Page 56 Version 3. Layers and Sequences coming from a particular inserted file. This determines how the geometry is to be inserted into the current part. If used.
Centre of rotation will be that of the target part not that of the source part s. Name Prefix. Name — Enter or Browse for the name of the. If this box is not checked only geometric entities will be inserted. If you choose Digitise. Insert a Component File Menu the part name is Component. When the command is executed. Open the part filed called Cube.
Fourth and Plane A 7. This feature is particularly useful when re-appraising a machining method of an existing component or when one wants to simply multi-load a machine tool table. This part represents a multi-load fixture plate that can accommodate four components. Exercise Inserting Multiple Components 1. Merge sequences allows a user to create a new machining sequence from several existing sequences.
The following exercise will not only demonstrate the functionality found in the Insert Component command but will also show two functions that compliment the command. Locate 2 etc 2. You will observe that not only has the component been inserted on to the correct CPL. This will be coupled to the Target CPL. The file is now easier to understand. Repeat the above process. You are allowed to combine multiple sequences.
Selected Sequences — Select the sequences you want to merge into the current sequence by moving them from the left to the right panel. The double arrow allows you to move all sequences to the right panel. Description — enter a name for the new machining sequence. You can do this by simply highlighting the required sequence s and pressing the single arrow. One may dictate the order in which the sequences are listed.
Remove Tool Positions — Check this option to set all tool positions to blank in the merged sequence. If this option is not checked. Force Index. Please note that option is only offered once for each merge commend and there will be no further checks for compatibility. Check this option to force the merge to use index commands instead of datum shifts.
Upon completion of the command. Section I1 Page 62 Version 3. You will need to re-specify these parameters for all toolchanges by editing the appropriate toolchange dialog.
If this option is checked. I1 EdgeCAM Advanced Milling Merge Command The Merge Sequences command allows you to merge two or more sequences into one by appending the instructions in the second and subsequent sequences to those in the current sequence.
Merge Sequences Instructions Menu is very easy to use. Open the Merge Sequences Instructions menu and state the name you wish to call the new sequence. Move into manufacturing environment. Merge Sequences 1. Inspect the Instructions Browser — you will observe four sets of Machining sequences — one for each component. Open the file called Loaded Fixture. Using the Save As command. Select the three remaining sequences found in the left hand panel and move them into the right hand panel Selected Sequences 3.
CPL or Index The sorted sequence is created as a new sequence and can easily be deleted.
Once you are satisfied with the re-ordered sequence you can delete the original sequence. I1 EdgeCAM Advanced Milling Rationalise command You can maximise programming efficiently by using the Rationalise command Instructions Menu This command will re-order a machining sequence to minimise the number of toolchanges or Index moves.
Section I1 Page 64 Version 3. Merge Hole Cycles. Check this option to group such instructions into a single cycle so that multiple.
You can choose between sorting the instructions by Tool default setting. The default setting for this option is OFF. Ensure that you have carefully checked the re-ordered sequence before deleting the original sequence. The original sequence will not be changed by the rationalisation process. The reordered toolpaths are placed in a separate sequence. Observe that a new sequence has been created.
In this instance we wish to Rationalise by Tool i. EdgeCAM will now go through the sequence ensuring the toolchanges are kept to a minimum. What will happen to the amount of toolchanges? How many toolchanges does the current sequence contain? Activate the Rationalise command Instructions menu selecting the strategy. Count the amount of toolchanges — there will be far less in the new sequence.
Inspect the sequence. You will notice that the tools 1 through to 5 are repeated four times over. It is not always the case that turret numbers will increase in sequential order. It is perfectly possible that the first tool to be used within a machining sequence is number 30 and the last tool within the sequence is number 7 Unless instructed otherwise. Any final changes to the tooling order can be achieved by adjusting the Sort Priority after rationalisation.
All tools with the same priority will be sorted by order of first use. If a Sort Priority has been assigned to a toolchange this priority will be displayed in the Instructions Browser to the right of the instruction number. To overcome this scenario.
Sorting will then be performed by order of first use within each priority group. Usage Tips: It is much easier to set the priority of tools in the individual part files when developing the machining sequence before rationalising the merged sequence.
We would suggest that types of tools are given a pre-defined number that relates to a type of operation. Section I1 Page 66 Version 3. EdgeCAM Advanced Milling For example you may wish to change the order of two roughing tools both have Priority by changing the sort priority for one of them to or It is necessary to check Multi level in order for the Multi Depth option to work. Exercise 13 — Multi Level Drilling 1. If arcs with a connecting vertical line are selected the depth will be taken from the vertical line.
Once all the final changes have been made run Rationalise by Tool again to re-order the sequence. Where an entity to define the depth is not selected the Depth parameter from the cycle dialog will be used. The cycle applies the Depth and Retract values relative to the Level of the digitised entity.
The Options allows the user to produce one machining cycle which caters for several hole features. The level for the cycle will be taken from the digitised geometry arc. Multi Depth — Code Generator dependent Check to drill a series of holes at different depths.
Your postprocessor must support Multi-Level Drill cycles Multi Level — Check to drill a series of holes at differing levels. Move into Manufacturing. Please note that it is still necessary to specify a Depth value which will not be applied. Any specified Level parameter value is ignored. This tool will create a 1mm centre at each hole position. Select a centre drill from the ToolStore. Remember the three set of holes are all at various Z Levels.
Drill Section I1 Page 68 Version 3. Move into the simulator and inspect the machining You will observe that the Drill will penetrate by 1mm on all levels.
As the cycle must learn the various Z heights from the model entities. Create a Drill Cycle — pay special attention to the Depth parameters. Save the part file Completed Z Levels. Simulate the procedure to check for possible errors. The purpose of the next cycle is to drill through the component maintaining the correct depth for each of the hole features. Referring to the centre drill method — window select the whole model in order to drill the component.
Create a Hole Cycle — observe the Depth values. It is also the center of rotation in multiplane milling. Specify the machine origin position. Machine Tool Ensure you have selected a postprocessor that contains the ability to index the tool in a rotary manner. Machine Datum. Initial CPL Address the possibility that the tool can be aligned with one of the indexing faces.
When designing a postprocessor through Code Wizard. Section I1 Page 70 Version 3. In the case of a standard Horizontal Borer. When the machine tool has the ability to index two axes. Using the Move Index command allows you to access each face of the component by choosing the previously created CPL. Section I1 Page 72 Version 3. Note that as the part is not shown to rotate.
Once the work plane has been re-oriented. EdgeCAM Simulator will display the component being indexed. Index can also be used to do a datum shift.
