The facts about iMachining SolidCAM's iMachining™ is an intelligent high speed milling technology, designed to produce fast and safe CNC programs to machine your mechanical parts with frst part success performance. The word fast meaning signicantly faster than tradional machining at its best and the word safe meaning without the risk of breaking tools or subjecng the

machine to excessive wear, all while maximizing tool life.

To achieve these goals, the iMachining technology uses advanced, patented algorithms to generate smooth tangent tool paths, coupled with matching condions, that together keep the mechanical and thermal load on the tool constant, while cung thin chips at high cung speeds and deeper than standard cuts (up to 4 mes diameter).

iMachining tool paths iMachining generates morphing spiral tool paths, which spiral either outwardly from some central point of a walled area, gradually adopng the form of and nearing the contour of the outside walls, or inwardly from an outside contour of an open area to some central point or inner contour of an island. In this way, iMachining manages to cut irregularly shaped areas with a single connuous spiral. iMachining uses proprietary constant load one-way tool paths to machine narrow passages, separang channels and ght corners.

14


In some open areas, where the shape is too irregular to completely remove with a single spiral, proprietary topology analysis algorithms and channels are used to subdivide the area into a few large irregularly shaped sub-areas and then machines each of them by a suitable morphing spiral, achieving over 80% of the volume being machined by spiral tool paths. Since spiral tool paths have between 50% and 100% higher Material Removal Rate (MRR) than one-way tool paths, and since iMachining has the only tool path in the industry that maintains a constant load on the tool, it achieves the highest MRR in the industry. iMachining also performs an automacally opmized tool path when nishing 2.5D features. The nish tool path is executed in several consecuve steps with intelligent tool movements, all of which would be programming intensive and dicult to achieve using tradional machining methods. Because of its highly systemac approach to nishing and dedicaon to eliminate over engagement, the iMachining technology is able to further maximize the life of your tools.

iMachining Technology Wizard A signicant part of the iMachining system is devoted to calculang synchronized values of feed rate, spindle speed, axial depth of cut, cung angles and (undeformed) chip thickness based on the mechanical properes of the workpiece and tool while also keeping within the boundaries of the machine capabilies (maximum feeds and spindle speed, power and rigidity). The iMachining Technology Wizard , which is responsible for these calculaons, provides the user with the means of selecng the level of machining aggressiveness most suitable to the specic machine and set up condions and to their producon requirements (quanty, schedule and tooling costs). An addional crical task performed by the Technology Wizard is dynamically adjusng the feed to compensate for the dynamically varying cung angle – a bi-product of the morphing spiral, thus achieving a constant load on the tool, which maximizes tool life.

This exercise is a step-by-step guide on the denion process of SolidCAM’s iMachining technology to perform the programming of the part above. For this rst exercise, the videos demonstrang the steps will also be accompanied by a wrien walkthrough. The rough and nish machining of the outside contour, center pocket and pocket ledge is dened. The machining will be performed on a 3-Axis CNC-Machine. The following steps have to be implemented in order to reach the nal CAM-Part:

1. Load the SolidWorks model Acvate the le SC_iM_Walkthrough.SLDPRT . SolidWorks will launch automacally and open the design model.

2. Create and dene the CAM-Part In this step, a New Milling CAM Project is created and the CAM-Part is dened. In addion, the machine and work material parameters are dened for iMachining.

3. Dene the machining of the outside contour In this step, the machining of the outside contour is dened. For this example, the geometry is dened as an open pocket with island. The Geometry, Tool and Levels are dened and the Osets are specied; the iMachining Technology Wizard automacally produces the opmal Cung condions. The roughing operaon is then copied and the iFinish Technology type is used to dene the nishing. Click the play buon below to watch the video. Following the video is also a wrien walkthrough to complete this step.

Right-click the Operaons header in the SolidCAM Manager and add a new 2D iMachining operaon.

To dene the machining geometry for the operaon, click the the Geometry page.

buon on

iMachining Geometry denions The geometry in iMachining is dened as a pocket that can be closed, open or semi-open (containing open edges). The following videos demonstrate how dierent types of geometries are dened in iMachining. Dening closed pocket geometries in iMachining This video focuses on several examples of closed pocket geometries and the tool path techniques that iMachining uses when cung those geometries.

20


Dening open pocket geometries in iMachining This video focuses on a few examples of open pocket geometries and the tool path techniques that iMachining uses when cung those geometries.

Dening semi-open pocket geometries in iMachining This video focuses on several examples of semi-open pocket geometries and the tool path techniques that iMachining uses when cung those geometries.

The completed CAM-Part is provided if you want to view the Geometry denions and the iMachining tool path techniques in SolidCAM. To open the completed CAM-Part, acvate the le SC_IM_2DGEOMETRIES.prz.

For this operaon, the geometry is dened as an open pocket with island.

21

Select the two chains as shown.

Mark the outer chain (1-Chain) as open to enable the tool to approach from the outside. Switch to the Tool page and add an end mill of Ø9 mm (0.3438 in).

Dene the remaining tool parameters as follows:

22

•

Keep the Total length of 80 mm (3.125 in);

•

Keep the Outside holder length of 60 mm (2.375 in);

•

Keep the Shoulder length of 30 mm (1.25 in);

•

Keep the Cung length of 24 mm (1 in);

•

Set the Number of utes to 4.


On the iData tab, the default 45 (Medium) value is used for the Helical Angle parameter. This parameter aects the Cung condions and Step down values generated by the iMachining Technology Wizard.

Click the

Helical Angle

buon to conrm the Tool denion.

Switch to the Levels page to dene the Milling levels for the operaon.

Click the Upper level buon and pick on the top face of the Stock model to dene at what Z-level to start the machining.

23

Click the Pocket depth buon and pick on the bottom edge of the Target model to define the machining depth.

Note that the Milling levels elds get painted red ‒ this is because the values are associave to the picked enes; and if the model changes, the associated values will update automacally. In addion to the picked depths, dene a Delta depth to perform machining deeper than the part boom edge. Set the value to -0.76 mm (-0.03 in). Switch to the Technology Wizard page of the iMachining Operaon dialog box. This Wizard automacally calculates the Cung condions for the iMachining technology, taking into account the tool data and Milling levels dened for the operaon.

24


Step down When the Automac opon is chosen, the Step down is calculated by the Wizard in accordance with the Pocket depth dened for the operaon. When the User-dened opon is chosen, the Step down can be dened by specifying a value or by seng the number of steps required to achieve the Pocket depth. The output grid displays the Number of steps, the Step down value and the number of Axial Contact Points (ACPs) calculated automacally by the Wizard. Rows are created for each Step down value that is not the same. Output cung data This secon displays two sets of data related to the current Cung condion (the Spindle speed and Feed rate of the tool, the Step over range, the material cung speed, Chip Thickness (CT), and the Cung Angle range). Machining level The Machining level slider enables you to select from calculated sets of Cung condions. Moving the slider up in machining levels provide a convenient and intuive way to control the Material Removal Rate (MRR). Increasing the posion of the slider increases MRR and machining aggressiveness.

For this operaon, use the Cung condions generated by the Wizard based on the default posion of the Machining level slider (3).

25

2D Example: iMachining of a Bracket

This example illustrates the use of SolidCAM’s iMachining technology to machine the part above. There are standard 2.5D tool paths (Drilling & Prole) and 3D tool paths (HSR & HSS) to aid in the complete CNC program. The machining will be performed on a 3-Axis CNC-Machine in two setups, from both sides of the part. To open the CAM-Part used in this example, acvate the le SC_IM_BRACKET.prz. If your CAM package does not contain the required 3D modules, acvate the le SC_IM_BRACKET_No3D.prz. The following SolidCAM operaons are dened to perform the machining: •

Outside shape machining (iRough_Outside; iFinish_Outside) These iMachining operaons are dened to perform the outside shape machining. An end mill of Ø12.5 mm (0.5 in) is used. Two chains are dened, with the rst being the stock boundary and the second being the prole around the part. The stock chain is marked as open, which species the tool should start machining from that chain. iRough has a 0.25 mm (0.01 in) allowance on the walls, which is then removed by the iFinish operaon. Both operaons have a -0.63 mm (-0.025 in) Delta depth, so the tool machines deeper than the part boom edge.

38


•

Through pockets machining (iRough_ThroughPockets; iFinish_ThroughPockets) These iMachining operaons are dened to perform the machining of the ve circular through pockets. An end mill of Ø12.5 mm (0.5 in) is used. Five closed chains are dened represenng the ve through pockets. Since the pockets are closed, with no Pre-Drilling data or entry chains dened, helical ramping is used to enter into the pockets. iRough has a 0.25 mm (0.01 in) allowance on the walls, which is then removed by the iFinish operaon. Both operaons have a -0.63 mm (-0.025 in) Delta depth, so the tool machines deeper than the part boom edge.

Rough machining of angled surfaces (HSR_R_Rough_Chamfer) This HSR operaon is dened to perform the rough machining of the four large chamfers on the ribs of the part. An end mill of Ø12.5 mm (0.5 in) is used. Two boundaries are picked o the edges that make up the chamfers. The Tool Relaon is set to Centered. A 1.27 mm (0.05 in) step down is used and a 0.127 mm (0.005 in) allowance remains on the surfaces.

Pockets machining (iRough_Pockets; iFinish_Pockets) These iMachining operaons are dened to perform the machining of the three semi-open pockets and the seven closed pockets. A bull nose mill of Ø10 mm (0.375 in) with a corner radius of 1.6 mm (0.0625 in) is used. Since all ten pockets have the same depth, they can all be machined in one operaon. The tool enters the semiopen pockets through the open edges. The tool enters the remaining pockets using helical ramping and the dened entry geometry. iRough has a 0.25 mm (0.01 in) allowance on the walls, which is then removed by the iFinish operaon.

Finish machining of angled surfaces (HSS_PC_Lin_faces) This HSS operaon is dened to perform the nish machining of the four large chamfers on the ribs of the part. A bull nose mill of Ø10 mm (0.375 in) with a corner radius of 1.6 mm (0.0625 in) is used. Parallel cuts are generated using a simple Linear strategy with a 0.5 mm (0.02 in) Maximum step over. Customized linking is used to allow short reposions and smooth transions when starng each cut.

Boom ledge machining (iRough_Face_BackLedge) This iMachining operaon is dened to perform the boom ledge machining on the underside of the part. An end mill of Ø12.5 mm (0.5 in) is used. Two chains are dened, with the rst being the stock boundary and the second being the boom of the oor radius. The stock chain is marked as open, which species the tool should start machining from that chain and collapse in towards the radius. The oor radius is not machined at this me.

•

Cung of excess material from through hole (iRough_Back_CenterHole) This iMachining operaon is dened to machine away the excess material from the center through hole of the part. This excess material was used for clamping from the rst setup. An end mill of Ø12.5 mm (0.5 in) is used. A single closed chain is dened and the default allowance is used for the wall, since the desired wall was nished during the top side machining.

Boom face machining (iRough_Face_Back) This iMachining operaon is dened to nish the circular face on the underside of the part. An end mill of Ø12.5 mm (0.5 in) is used. Two chains are dened, with the rst being the outside boundary of the face and the second being an oset edge created in SolidWorks. The tool starts machining from the outer open chain and collapses towards the inner closed chain.

•

Floor radius nishing (F_BackRadius) This Prole operaon is dened to nish the 6.35 mm (0.25 in) oor radius on the underside of the part. A ball nose mill of Ø12.5 mm (0.5 in) is used. The chain is dened as the boom edge of the radius. The Tool side is set to Center. A 0.13 mm (0.005 in) oset is le on the oor aer the rst roughing pass and then removed with a single nishing pass. A 0.25 mm (0.01 in) arc is used for Lead in/out.
