Using Teamcenter and Solid Edge helps Kam-Avida dramatically reduce rejection and rework rates

Designing, manufacturing and servicing of waste management machinery just got easier and more efficient

Modernizing waste management

Rapid industrialization in India is bringing new challenges to the waste management industry. Waste collection, disposal and recycling have traditionally been done by hand. India’s poorest people were the waste managers, earning a meager living doing the work that no one else was willing to do. The proliferation of industrial waste today adds a much higher level of difficulty, because the waste is even more hazardous to humans.

Kam-Avida Enviro Engineers Pvt. Ltd. (Kam-Avida) offers solutions to these problems. Based in Pune, India, Kam-Avida designs and manufactures machinery used for sewer cleaning, road sweeping, garbage collection and transport, industrial spillage collection, and the recovery of bulk material and non-volatile hydrocarbons. Much like automotive and aerospace original equipment manufacturers (OEMs), Kam-Avida designs its own machinery and then contracts with suppliers for major systems and components, assembling the final products at the company’s factory in Pune.

In an interview published in OEM Update (March 2011), M. Krishna, Kam-Avida’s managing director, says, “In line with our corporate philosophy of cleaning and maintenance with ease and dignity, we are committed to bringing about mechanization.”

In the same interview, Krishna added, “This is a completely neglected activity. Modern India still suffers from the archaic methods of manual cleaning, putting to risk the cleaning crew and compelling them to use outdated tools for carrying out this important task. It is due to this lack of concern that this entire group of professionals suffers from an undignified existence, unlike their counterparts around the world.”

Data management difficulties

Kam-Avida experienced a number of issues relating to releasing drawings, especially keeping track of revisions. “We faced a number of problems,” notes Ganpat Dhanavade, who directs Design and Development. “Sometimes, different drawings were released with the same drawing numbers. Vendors worked from different drawings to manufacture the same component, which led them to ship us components with different dimensions. This resulted in rejecting components and reworking those same components. It was simply taking too long to deliver our machines.”

Design engineers at Kam-Avida spent a lot of effort trying to keep track of drawing revisions. The company tried using drawing checker software, but that only made the process more time-consuming.

Advanced PDM and CAD

Seeking to significantly improve its product lifecycle management (PLM) operations, Kam-Avida began evaluating advanced solutions for product data management (PDM). It also started assessing solutions for 3D-based computer-aided design (CAD). After a thorough analysis of its best options, the company chose Teamcenter® software (preconfigured for rapid deployment and fast return on investment) for PDM and Solid Edge® software (enabling accelerated design, faster revisions and better data re-use) for CAD. Both solutions are from Siemens PLM Software.

“We needed to be able to release correct, error-free drawings for a project, and we wanted to be able to release those drawings within one day,” says Mr. Ganpat Dhanavade. “In addition, we needed to fix our problems without adding new staff; therefore, we sought to dramatically improve the efficiency of our design engineers.

“Implementing Teamcenter and Solid Edge made the difference. We are no longer facing any problems in releasing drawings and keeping track of drawing revisions. This is now a fully automated process enabled by the software. Today, each drawing has a unique drawing number. Vendors making the same component work from the same drawings. Suppliers ship us the right components with the right drawing dimensions.”

Rejection rate and rework significantly reduced

Dhanavade notes that the rejection rate and rework of components sent by suppliers has been remarkably reduced – from 60 to 0.5 percent. Product delivery time from order to customer has been reduced from 45 to 5 days.

According to Dhanavade, the company is now concentrating on innovation, with plans to continuously improve the performance and quality of its machines to help address India’s waste management challenges.
