You don’t need to purchase brand new machine tools to incorporate into FMSs

There has been a prevailing myth that manufacturers need to purchase brand new machine tools to incorporate into FMSs. That simply is untrue. Automating existing machine tools is possible and common. There are ways to navigate through the necessary technical landscape surrounding machine tool interfacing, table or chuck access, safety and more. To help manufacturers through this transition, Fastems has published “The CNC Automation Guide for Existing Machine Tools.”

According to Fastems, successful shops are defined by their willingness to invest and trust in new technologies. For all but a handful of manufacturers, though, refreshing their collection of machines every few years – or every few decades – is just not feasible. Luckily one of the most efficient methods of boosting production doesn’t require the latest and greatest equipment. The average non-automated machine cuts only approximately 20 percent of a full day. Put in the context of an entire year, only about 1,752 hours out of the 8,760 total available annual production hours are being used. Automation unlocks that wasted 80 percent.

A rising trend

In practice, existing machine tool automation or “EMTA” can mean automating completely stand-alone machines, machines that are already integrated into an automation system, or a hybrid of the two. In all its forms, EMTA has experienced an increase in demand because automation can boost production capacity tremendously and brings unique opportunities when floor space is limited. In addition to this, the classic production development parameters around machine tool utilization rate, lead times, their reliability, profitability, quality, as well as employee engagement are also very important, and a desire to improve in these often drives EMTA. On top of this, production might be lacking in analytics and KPIs, which are things automation can provide instantaneously. Finally, sometimes the existing automation hardware is malfunctioning, or there is a business risk which needs to be solved. In sum, all the so-called traditional benefits of automation are accessible for EMTA cases, and a desire for them usually drives the investment.

Automation Options

Automation can be divided into two categories: digital and physical. Digital automation encompasses automated production planning and resource management, like Fastems Manufacturing Management software (MMS), a software that automatically optimizes workflow by organizing labor and materials according to past data. Digital automation maximizes spindle uptime, minimizes scheduling blunders, and provides a current and informed plan for raw materials, tool, and machines. Physical automation solutions are hardware setups that can manipulate materials and tools. Pallet systems are designed to move pallets to workstations according to optimized production plans, saving time and labor. Robots can manage the movement of tools for deburring, washing, measuring, and marking.

Integrating New Automation with Existing Equipment

Installing automation systems is less about adding new tools so much as honing existing tools. The advantage here is that manufacturers won’t have to buy new machines, especially when budget or floor space is a limiting factor. To integrate seamlessly, though, companies should take an intelligent approach to project management, interface selection, interface development, and making physical changes to current machines. Failing to make a successful integration could result in manufacturing planning software that offers inaccurate data, robots that mishandle their loads, or simply a general decrease in throughput.

The Guide details all the key aspects of automating existing machine tools, including Project Management, Interface Selection, and Making Physical Changes to Machines.
