Rentapen Inc. gets recognized for their participation in Waukesha County Technical College’s Co-op/Internship Program.
WCTC awarded Rentapen with the Certificate of Appreciation for their active participation in the Co-op Internship Program.
Rentapen inspires and guides student-trainees for the potential workforce.
For example, Peter Christiansen is a student at WCTC who joined the Rentapen team as an IT Intern. Christiansen started interning at Rentapen in August 2011.
Christiansen is creating a program that will make it easier for jig and weld fixture design engineers to download 3D models of Rentapen’s RAPid Tooling Components™. The design engineers will be able to get 3D models that can be placed in their Computer Aided Designs (CAD). So now engineers who are designing weld fixtures can go onto Rentapen’s website www.rentapen.com and pull down a 3D model of a block, plate, clamp risers, or shim pack. From there, they can put it right into their Pro/E or Solidworks designs.
Christiansen is graduating with high honors from WCTC, with an Associates degree in program analyst and web/software analyst development. He is planning on joining the Rentapen team as a full time employee on December 20, 2011
“I’m excited to be done with the program and happy to contribute to the workforce,” said Christiansen.
Christiansen used to work in the Casting Industry as a quality control inspector, until he was laid off. Christiansen decided to go back to school for his Associates degree as a programmer analyst.
“We are pleased to have Peter join the Rentapen team full time. He is already familiar with the Manufacturing Industry and fixtures so its easy for him to understand our product line,” said Susan Straley, President at Rentapen Inc.
Rentapen is always introducing new product models to fit their customers’ needs. Christiansen will be in charge of making the product models available at Rentapen’s website.
Rentapen Inc. offers internships in design engineering, CNC operating, laser cutting, and information technology.
Today we will discuss some of the questions that help you decide the material, modeling method using Pro/E 4.0, and fastener locations.
1) MATERIAL —
First decide what material you will need the v-block to be.
How much will the fixture be used? That means knowing what the product is made of because we need the v-block to be strong enough not to wear down too quickly. We want to be able to produce lots of product before we have to replace any of the parts in the fixture. The more the fixture is going to be used the harder you need to make the v-block relative to the product tube or rod.
Do you need to plan for weld splatter?
If the v-block is located near the weld joint, you will need to consider using a metal that the weld splatter will not stick to as easily, or using a weld splatter shield. Remember that like metals stick better. So if you are welding steel, you may want your v-block to be Ampco 18 bronze or a hardened steel such as 4140 PH or A2. If you are welding aluminum, hardened steel may work just fine.
2) TOLERANCING –
Is the location of the rod or tube critical?
If the tube or rod needs to be located in just the right spot in order to work or assemble easily to the rest of the product parts, then you will want to design in adjustability with shim packs. You will need to look at the product drawing and also know your customer’s preferences.
At Rentapen we design for many different customers. So we have to consider the standards and preferences of each customer when we design. Some of them love to shim every locator in a fixture. Some of them don’t like to shim at all. If you are a CAD drafter, you may be working under more than one designer. Each designer may have their own preferences. But it is up to you to look at the product drawing and then advise them when you think shims will be needed to meet the tolerances of the product drawing. Then do what they say, they are your customer.
If it is a rough location, you may be able to use a purchased V-block from somewhere. Do you have a favorite model or brand you would like to share?
3) FASTENERS –
Once you have decided if your v-block will have shims to fine-tune its location before going into production, you can decide about the location of the fasteners. If the tube or rod location is critical, you will need to use dowels to lock in the location. If it is rough, you can just fasten the v-block directly to the base plate with screws.
4) MODELING —
Locating the Vee in the v-block.
Here is how I model in the Vee cut. Click on the video to see my method using Pro/E Wildfire 4.0.
In this video I dimensioned the construction hole from the BOTTOM of the block. However, the v-cut may fail if I make an adjustment too big in one direction or the other. Some of the project engineers I have worked with prefer that the dimension for the V-cut be from the TOP surface of the block. That way you can change the size of the block without having problems with the cut.
Some like to create planes that intersect at the center where the the construction circle will be located. These planes are created before you start the sketch to cut the Vee. I think your preference depends on your experience and how your brain works when making adjustments to parts while in the assembly.
5) CLAMPING —
Clamping is a whole topic by itself that we will address in a future blog. I just wanted to note that it is something that you need to think about. We always clamp down our parts in weld fixtures, even if it is a table mounted fixture and gravity does its work. You want to be sure that tube doesn’t move when the heat of the weld hits it.
And now I would like to share a couple of things with you.
First, Rentapen’s Holiday Greeting to our customers, vendors, students, and friends.
Manufacturers Utilize Education to Motivate and Retain The Engineering Workforce.
According to the National Science Foundation, Division of Science Resources Statistics, “The majority of individuals in the labor force with Science and Engineering degrees are in their most productive years, (from their late 30s through their early 50s), with the largest group ages 40-44.”
So what keeps these engineers inspired in the work force?
“Education and learning more software is one way to get engineers ready for work force opportunities,” said Susan Straley the President of Rentapen Inc.
As the engineering workforce changes, employers implement retention and training programs. For example, Rentapen Inc., located in Waukesha, Wisconsin recruits and trains engineering interns. Rentapen has also implemented an education reimbursement program to keep their current engineer’s skills updated and their workforce motivated.
One of Rentapen’s design engineers is expanding his knowledge and updating his skills. Curtis K. a CAD Drafter at Rentapen Inc. just finished his Solidworks course at WCTC on Thursday, December 15, 2011.
Curtis has worked for Rentapen for one year and already has furthered his education to keep current with Rentapen’s 3D design services for customers.
“It is very important for a machine design company such as, Rentapen to have their engineers trained in both Solidworks and Pro/Engineer because Rentapen’s customers don’t all use the same software for their machine designs,” said Straley.
Curtis has five years of experience in Pro/Engineer and is beginning to work with Solidworks.
“I felt I needed to take the class because when I start working with Solidworks it will be easier for me to understand the software,” said Curtis K.
Rentapen, a company that specializes in jig and weld fixture design, encourages its employees to take advantage of Rentapen’s education reimbursement programs. Since Rentapen’s design customers dictate what software they want their machine designs created on. It is vital for Rentapen’s design engineers to have education in both softwares.
