FreePoint Helps A Customer Increase Their Productivity By 42%

The following case study demonstrates how FreePoint’s technologies were successfully used by their customer to help increase the productivity of a critical machine by 42%.

The customer is a leading international manufacturer and distributor of high quality die sets, components, steel plates, and metal fabrications used in the production of tools, dies, and molds. The following figures demonstrate the impact of FreePoint Technologies’ system.   

During FreePoints ShiftWorx training in November 2015 with the client, ShiftWorx tools were used to assess the impact of the company’s recent continuous improvement project with a critical vertical machining centre. In September 2015 the customer implemented a change in their process, and FreePoint decided to use that situation as a training example.

The first chart below shows the active machining time for the machine from October 1, 2015, to June 30, 2016. FreePoint used this period to establish a “baseline” from which to compare the future improvements against. The period was selected for the following reasons:

  • The machine was operated by the same operator for the same shift in a steady fashion for a long period of time
  • The period did not include the traditional vacation period (July and August)
  • Workload varied from week to week and month to month, but a 9 month period leveled out the peaks and valleys.
  • “Zero days” show up on the chart but are excluded from the average calculation.
  • The percentage are based on a 24 hour (or 1440 minute) “day”. They can easily be converted to a shift by multiplying the percentage by 1440 (total for a 24 hour day) and then dividing by the minutes in that shift. (For instance, 11.72% of a 480-minute shift would be 35%)

The chart below shows that on average, the machine operated 11.72% of a 24 hour day, or 169 minutes of “value adding” time on a single 8-hour shift, which equates to 34.2%.


For comparison purposes, the following chart shows the summer months – June 2015 and July 2015. There are 3 weeks of inactivity, likely due to holidays or lack of work for the machine. The daily average is down a bit, to 10% of a 24 hour period, or 144 minutes or 30% for the 8-hour shift.

The month of September shows a slight increase over the pre-summer numbers, at 12.75% of a 24 hour period, or 183 minutes of value adding time per day or 38% for the 8-hour shift.

The month of October comes in at 13.46% of 24 hours, or 194 minutes or 40.4% of an 8-hour shift.

And finally, November 2016 (up to November 25th) comes in at 16.76%, or 241 minutes of value adding activity, equal to 50.2% of the 8-hour shift.

This represents a 42.6% increase in value adding machining time when compared to the baseline established for the 9 month period from October 2015 through June 2016.

We had the opportunity to ask the customer some clarifying questions to gain an insight into the effect FreePoint Technologies had on their business.

Q: What problem were you trying to solve?

A: The problem we were trying to solve was to reduce setup times on the machine and to increase the time the machine was working.

Q: What change or changes made the biggest impact?

A: The two biggest changes were that we added setup vises for clamping material, and made changes to our programming. Parts are put in vice and clamped square, reducing setup time on the first side. We also made changes to the program so that the face head was in contact with the material making chips more often. We did this by reducing air passes and reducing program editing by the operator.

Q: How long did it take to implement the change?

A: It took about 2 weeks to implement the changes and we saw results immediately.
