The February 2017 Modern Machine Shop article, “Managing Risk”, detailed how Protomatic developed a PFEMA system to identify more than 300 potential failure modes and procedures to mitigate those risks. The article has created a flood of requests for more information. We are providing the following to give more information to customers concerned with extracting the best quality from their suppliers.
A lot of companies simply do not have the time to evaluate their supplier base. Unfortunately, this means there is little or limited communication between quality and management teams. To bridge that gap, Protomatic brings you these newsletters on a monthly basis. We hope you find them informative and educational.
Manufacturing job shops typically interpret a material specification of “ALUMINUM 6061-T6” as allowing 6061-T6, -T651 or -T6511. All of these are acceptable tempers, and are permitted for most applications. But, from years of experience, this is not necessarily the best interpretation.
While there is a wide array of metal coatings and finishes available, the following overview highlights many of the options that are most commonly used by design engineers. All have unique properties that can protect or optimize product performance; many reference a military specification; and most are processed by NADCAP suppliers. If you would like more information, most military specifications are public domain and are available at http://quicksearch.dla.mil/
Using the proper finishing process is critical to any CNC machined part. Of course, one major benefit is the parts just look better. When parts are unfinished, the often look incomplete. The right finish conveys a perception of higher quality, which customers certainly appreciate.
Lights-out manufacturing is the ability to manufacture in an unattended state for an extended period of time. At Protomatic, our definition of “proper lights-out manufacturing” is to be able to manufacture during the week (second and third shift, 16hrs) and over the weekend, with its largest unattended time of 86hrs, from Friday 4:00pm to Tuesday 6:00am (assuming a Monday holiday).
You have probably heard in the news that cyber events, or website hacks, are occurring more and more frequently. Several large department stores have lost credit card information, private emails are being shared with the public, and even the organizations with knowledge of how to protect their data have been hacked or held at ransom.
Technically small parts are hard to make. As you get smaller, challenges arise. Deburring, machine accuracy and tool quality are just some of the problems that are experienced when making small part features. Protomatic has the equipment, tools and expertise required to successfully manufacture the tiniest of parts.
Customer-provided CAD math data is critically important to manufacturing. It expedites quotations, and is used in the CAM programs to create the CNC program used to manufacture parts, and the CMM program to inspect them. Historically, Protomatic has received CAD math data from customers along with a paper print with tolerancing information.
