· Recommended: Create production work using geometry constrained by dimensions or geometric constraints. (page 6)
· Ready to create first sketch
· We will
· Create a Sheet Metal Part
· Create a base sketch
· Define a basic sheet metal style
· Create a sheet metal face from the sketch
· Add a flange to the first face
· Cut material from a face (page 7)
· Add Sheet Metal Features
· Adding more faces and flanges
· Adding corners and bends
· Creating a flat pattern
· Adding holes to the part on your own, using the skills you have learned in previous tutorials (page 8)
· Sketch First Face
· Click Two-point Rectangle tool
· Draw 250 x 200 mm rectangle
· Watch co-ordinates at bottom right of screen
· We should constrain with dimensions and center at origin (page 9)
· Using Sheet Metal Tools
· In base sketch include principal face or open profile for shape of contour flange
· Styles control sheet metal parts
· Type and thickness
· Bend radii
· Bend relief
· Corner options
· Other setting unique to parts formed from flat sheets
· We will modify material and thickness next (page 10)
· Create a Sheet Metal Style
· Right-click panel and select Sheet Metal Features panel
· Click Sheet Metals Styles
· Click New in Sheet Metal Styles dialog box. The default style is copied to new style and inherits all its parameters
· Rename Copy of Default to Brass, Soft Yellow
· Next we change material and thickness before saving new sheet metal style (page 11)
· Save Sheet Metal Style
· Select Brass, Soft Yellow from Materials list and change thickness to 2.5 mm
· Click Save button
· Make new style active by selecting it in Active Style drop down list
· Done (page 12)
· Create First Face
· Click Face tool and accept defaults
· Click OK
· Rotate view to shorter side vertical (page 13)
· Add Flange
· Click Flange tool
· Select left inside edge of part
· Use 50 mm distance
· Click OK
· Save to s_metal.ipt (page 15)
· Sketch a Cut Face
· Click Sketch tool
· Click front face
· Click Two Point Rectangle Tool
· Draw rectangle to partially overlap lower right corner
· Select collinear constraint and make verical and horizontal edges of rectangle to edges of face
· Do each with two picks each
· First on rectangle verical line
· Second on vertical edge of part
· Similarly for horizontal line on rectangle to be collinear with lower horizontal edge of part
· Esc to end constraint command (page 16)
· Dimension Sketch and Create Cut
· Horizontal: 175 mm
· Vertical: 100
· Click Cut Tool
· Select inside rectangle
· Click OK (page 17)
· Create Offset Work Plane
· Click Offset Work Plane tool
· Pause over front face and drag inward
· Enter 50 mm in Offset dialog
· Click Check Mark to place (page 18)
· Create Sketch Plane for Offset face
· Click Sketch tool and select an edge on work plane
· Look At tool to view planar sketch (page 19)
· Create a Sketch
· Draw approximate rectangle inside lower right corner of plane
· Click Collinear Constraint tool
· Align rectangle vertical and horizontal edges with that of part face (page 20)
· Right-click, select Done for collinear command
· Right-click and select Finish Sketch
· See: Using Constraints tutorial (end of page 21)
· Create Offset Face
· Go to previous view
· Click Face tool
· Click OK (page 22)
· Next create another offset face
· Create another work plane
· Click Work Plane tool
· Click existing work plane
· Drag forward
· Enter 25 mm in Offset dialog
· Click Check Mark or press Enter key (page 23)
· Sketch tool > planar view with Look At tool
· Draw second rectangle and collinear lower edge to lower horizontal edge of part
· Right-click and Done for collinear command (page 24)
· Create Offset Face with Face Tool as before (page 25)
· Add Flange
· Click Flange tool
· Use the 50 mm Distance (page 26)
· Create New Flange
· Click OK
· Save
· Faces and flanges are defined (page 27)
· Add Sheet Metal Bends
· First a right angle bend
·
Click
· Select two edges
· Radius: 5 mm
· Click OK to create bend (page 28)
·
Create Second
·
Click
· Click two edges (upper of first rectangle face and lower of cut face)
· Radius: 10 mm
· Click OK to create bend (page 29)
· Chamber two edges
· Click Corner Chamfer tool
· Select the tiny edges of first rectangle face
· Click OK
· Inventor ignores inconsistent edges (page 30)
· Add Two Corner Rounds
· Click Corner Round tool
· Click two corner edges of second rectangle face we created on Work Plane2
· Click in Radius field to view arrow
