the home of Bend-Tech software
Scott from WI... Easy to learn and takes the guess work out of the job. Blows the competition away.
Andy from CA... one of my friends asked me "is it worth it?" without trying to laugh I said yes, of course it was. ... I spend less time and waste nothing, I make more money!!! this program could sell for 10 times more and it would be worth it.
Marc from Great Britain... We purchased the Bend-Tech SE programme at the same time as our new bender (ercolina madrel bender). We produce our own sportscars which accept many different engine choices, using the programme we can alter all our standard chassis parts in seconds to allow custom engine / gearbox fitments, also we able to supply accurate custom roll cages with ease thanks to this programme.
Bend-Tech SW details
What is Bend-Tech SW?Bend-Tech SW is a software application that allows a user to design tubes, pipes and rods in SolidWorks™, then within SolidWorks™ send part geometry directly to Bend-Tech to calculate correct manufacturing instructions.
Which SolidWorks™ features are recognized? Bend-Tech SW will allow you to work with Sketch Lines, Sweeps & Weldments.
How does it work? After completing your tube design, select the Bend-Tech icon or pull-down menu within the SolidWorks™ framework and select the green check to send it to Bend-Tech. Within Bend-Tech, select the tooling corresponding to the radii in your part, or allow Bend-Tech to select if for you from a tooling to radius relationship table. In an instant your manufacturing details are available.
Can elongation be calculated? Absolutely!!! We have a simple testing procedures that you perform with your tooling and material. From this, you will obtain values in your Bend-Tech tooling library to calculate correct bend lengths.
Will Bend-Tech SW calculate spring back? Yes. Bend-Tech SW creates its own internal formulas from a data history file of your materials, tooling and machines. With this Bend-Tech calculates the Spring Back Angles for your job.
Will Bend-Tech SW work with my bender? Yes. Bend-Tech provides proper cut lengths, bend locations, bend angles and rotations for all machines. This includes all manual, NC or CNC machines which are rotary draw, rotary compression or center compression benders.
Do I need to design in SolidWorks™ with the correct tooling radius? No. This is a problem for many job shops. Often, part files from their customer’s engineers who may not be familiar with the shop’s production tooling. To solve this problem, once a part has been sent to Bend-Tech you can change a single radius or the tooling of the entire part with a single mouse click. Bend-Tech will then instantly adjust your part length and bending instructions.
Will Bend-Tech SW provide XYZ or LRA data? Both!!! Bend-Tech SW provides proper centerline apex XYZ values and LRA data (LRA; Length Rotation & Angle; also known as YBC). Bend-Tech have several different charts to choose from and accommodates the variation in structure formats for bend locations and rotations.
What versions of SolidWorks™ does Bend-Tech SW support? As of the date of this document, Bend-Tech SW supports 2007, 2008, 2009, 2010 & 2011
The XYZ interface allows you to key in the features of your part in a sequence following the center line of the material. Most bends are entered in using the "apex" dimension type. Apex is the intersection of two straight tubes. You will find that a user can use different dimension types when you have bends of 180 degrees (use tangent or perp) or when you desire to have the software define the radius of a bend in a "crown" environment.
environment allows a user to enter in the height of a crown and the software
will calculate the radius, bend angle and the adjacent bends angles as well.
This feature is used commonly for "T" tops in boats.
With a single click of the mouse you can have all of your values switch between inches and millimeters.
Select the "print" command and 2 setup pages will come rolling out of your printer. The first page gives you the detail information to make the part and the 2nd will provide a cartoon strip of transitions showing you graphically how to load and bend your material.
The Tooling library consists of CLR (radius), Calibrated CLR, Bend Location Offset, Tooling Limitations and User Defined Definitions.
The calibration is done with a simple to follow calibration interface. The calibration allows users to hold the tightest of tolerances. Customers using CNC equipment are able to hold .005 on the first part and customers using manual equipment will most often be able to get to a 1/32 of their target in the first try.
The Bend Location Offset defines the distance on some benders between the start of the bend and the reference location for lining up the bend marks.
The sketch interfaces uses pick points for dimension locations. In the case below the pick points are a cyan color. These pick points eliminate the need to spend significant time describing a dimension location.
During the sketch process you have the ability to suppress and display several different types of pick points.
SW allows for different tooling from bend to bend on a single part.
"Cut Off" allows to add extra material to the end of the tube for post bending cutting. This is used largely for cutting to place one tube against another. In this example we added 2 to our value so the cut length grew by 4 and each bend was moved 2.
We can change the "Decimal / Fraction" fields to allow for tolerances of 1/4 to 1/32 and decimal places from 0 to 0.000. In this example we changed the fractions to 1/32.
You will also find an example of a center compression bender. Some customers have been known to use the center choice for sheet metal fabrication.
"Rotation" in our results window uses positive and negative numbers to represent clockwise or counter clockwise. Depending on which end of the machine you are standing on this can be very confusing, so we have given you the ability to reverse the sign to signify rotation direction.
The values for the 4th and 5th bend have changed as well. This is because we are now providing the location values on the other end of the bend zone so when the part is flipped the correct end of the tube is marked. This allows for measuring from one end for the cut and all of the bend locations.
We also have the ability to reverse the order of bending. This allows you to engineer the part from one end and start manufacturing from the other. The maybe need when your part will have interference with the machine, floor or other obstacle. At times by switching the bending order we can avoid these interferences. Refer to the simulation section to see this in action.
As displayed below, a user can change the locations to the straight leg length between bends, display the length of the bend, change the rotation to incrementally from 0 to 360 or absolute from -180 to 180 or to 0 to 360.
With Assembly: Bend it right the first time, every time & Design it right the first time, every time!!!
Assembly Design: Creation of parts can be done in Assembly or using Bend-Tech's standard methods like; templates, custom part, custom 3D, etc... Assembly uses common terms for design; to front, back, left, right, ceiling and floor. Parts can be rotated or mirrored at anytime. If a part is created or altered in Assembly it can be sent back to part design for correct cut length, bend locations, rotations, angles and simulation.
Dimensioning: A single part or an entire Assembly can be dimensioned. Dimension types include; horizontal, vertical, linear and angular. Dozens of settings are available for the dimensions including; colors, sizes, angles, tolerances, etc....
Cutting: Assembly can create a to-scale template or wrapper for cutting or fish-mouthing. Any number of tubes and sizes of tubes can intersect. There are 2 calibration lines on the template; linear location and rotational location.
We create a part by starting at one end and entering in the lengths and angles for each bend. The dim type can be Apex or Tangent. Apex is the intersection of the 2 tube sides as if they have a zero radius and zero diameter (basically 2 lines).
This part shows the 180 degree bend using a tangent dimension and the 90 degree bend uses an apex dimensions. Note: a positive angle strokes counter clockwise and a negative angle dimension strokes clockwise.
All 3 of the parts are exactly the same. The first one shows using 2 apex dimensions, the second shows using 2 tangent dimensions and the last has 1 apex and 1 tangent dimension. In our case the CLR is 3.5
Now SE's custom part has rotational input!!!. If you know your lengths, angles and rotations, this is the interface to use.
We use terms that are easy to understand for direction control during the creation of the part. These terms are; left, right, front, back, ceiling and floor. If you are familiar with XYZ then the front is +X, back is -X, left is +Y, right is -Y, ceiling is +Z and floor is -Z.
This interface is incremental, which means we are looking for the distance from bend to bend. The numbers buttons above the input star are the bends, E stands for the end of the part.
There are dozens of pre-defined templates to choose from. Most templates allow for center, outside and inside dimensions. While scrolling down the list of templates, they graphically show up in the window on the right.
The templates are read in from a secondary file. This allows us to periodically create new templates and have them available for download.
The below picture shows the values have been entered. Notice how the input values can be fractions using the templates. For this part our cut length is 101 9/16 and our bend locations are 20 7/8, 36 15/16, 60 and 76. The results window can be in fractions with definable tolerances from 1/4 to 1/32 or use decimals up to 3 places.
Includes 17 templates specifically designed for the railing fabricator. Click here for more details
Simulation was designed to help fabricators visualize the process before standing in front of the machine. This helps to determine the manufacturability of the part and the order in which we are bending it.
The simulation window works like a cd or tape player. You can have it run through the bending at the speed you desire, pause it, go frame by frame, etc..
As the simulation is taking place the results window shows the bend it is on with a green shaded box.
SW allows for values to be set up in the tooling library to check for manufacturing restrictions. If the part you design is flagged as falling within your restrictions than a warning button is displayed in bright red. The warning will tell you where the problem is and in the case of not having enough material at the ends, SW will allow you to select the warning field and the need amount of material is automatically added.
SE's Spring Back Charts are designed to help you to eliminate those stacks of setup pieces. The Spring Back Charts utility will allow you to put in numbers of spring back that you know and the software does the rest. You will find the "Results" and setup sheet will now have an additional column which includes your spring back angles.
One of the ways to reverse engineering in SW is to design the part using the tangent distances between bends and use the radius the part was manufactured with. When you are done you can push one button and enter in the new radius. SW will adjust the lengths of the straight sections to match the new radius. Note how the profile in the picture below is the same with the exception of the 2 different radii.
This feature is also very popular for customers who receive prints where the straight sections of tube are dimensioned, however, the radius that was used in designing the part was incorrect.
LRA to XYZ:
SW will transfer any part into a XYZ data. Most common this is when you enter LRA information into the Custom Part interface. The XYZ data is available by pushing one button.
