What is machine uptime?<\/h2>\n

Machine uptime is defined as the time a piece of machinery was available and operational in a given time period.\u00a0<\/span><\/p>\n

It gives us a sense of how reliable a machine is \u2014 a high machine uptime indicates high machine reliability and vice versa.<\/span>[\/vc_column_text][\/vc_column][\/vc_row][vc_row kd_background_image_position=”vc_row-bg-position-top” css=”.vc_custom_1687442797424{margin-top: 40px !important;}” el_class=”limble-page-blog-width”][vc_column][vc_column_text]<\/p>\n

How to calculate machine uptime?<\/h2>\n

The opposite concept of machine uptime is <\/span>machine downtime<\/span><\/a>.\u00a0<\/span><\/p>\n

When you have the numbers for one of those metrics, calculating the other one is trivial. You just need to subtract the figure from 100.\u00a0<\/span><\/p>\n

The equation to calculate machine uptime is as follows:<\/span><\/p>\n

<\/p>\n

Machine downtime is easier to observe and record. Due to this fact, the common methodology is to calculate machine downtime and subtract it from 100 to get the figure for machine uptime.<\/span><\/p>\n

Machine Downtime<\/b> = (Number of seconds machine was down \/ Total number of seconds observed) *100<\/span><\/p>\n

Machine Uptime<\/b> = 100 \u2013 Machine Downtime<\/span><\/p>\n

Example of a machine uptime calculation\u00a0<\/span><\/h3>\n

You are observing one of the conveyors in your facility. If the machine was down for 30 minutes in a window of 12 hours you were observing, you can calculate its uptime by inserting the figures into the equation above.<\/span><\/p>\n

Machine Downtime = (30*60)\/(12*60*60) *100 = 4.17%<\/span><\/p>\n

Machine Uptime = 100 \u2013 4.17 = 95.83%<\/span><\/p>\n

Therefore, in our example, the observed conveyor had the uptime of nearly 96%.<\/span>[\/vc_column_text][\/vc_column][\/vc_row][vc_row content_placement=”middle” kd_background_image_position=”vc_row-bg-position-bottom” kd_top_separator_style=”skew-left” kd_top_separator_height=”separator-height-small” kd_bottom_separator_style=”skew-left” kd_bottom_separator_height=”separator-height-small” kd_top_separator=”true” kd_bottom_separator=”true” css=”.vc_custom_1682969576554{margin-bottom: 40px !important;padding-top: 120px !important;padding-right: 40px !important;padding-bottom: 50px !important;padding-left: 40px !important;background: #dde4e8 url(https:\/\/limblecmms.com\/wp-content\/uploads\/cta-laired-hex-4.webp?id=9077) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;border-radius: 0px !important;}” css_tablet_landscape=”.vc_custom_1682969576554{padding-bottom: 80px !important;}” css_tablet_portrait=”.vc_custom_1682969576555{padding-bottom: 80px !important;}” css_mobile=”.vc_custom_1682969576555{padding-bottom: 80px !important;}”][vc_column][vc_row_inner kd_background_image_position=”vc_row-bg-position-top”][vc_column_inner]

Example of low equipment uptime<\/h2>\n

In order to avoid production interruptions, your machines have to be available and operational throughout the production cycle.\u00a0<\/span><\/p>\n

The production consists of multiple processes done in a sequence. When a machine experiences <\/span>unplanned downtime<\/span><\/a>, the processes that are upstream and downstream from the failed machine are affected.<\/span><\/p>\n

Let\u2019s say a production process involves five steps in this sequence:\u00a0<\/span><\/p>\n

    \n
  1. Cutting<\/span><\/li>\n
  2. Machining<\/span><\/li>\n
  3. Joining<\/span><\/li>\n
  4. Polishing<\/span><\/li>\n
  5. Quality check<\/span><\/li>\n<\/ol>\n

    The machine required for the joining phase of the production is experiencing failure. The polishing and quality check stations remain <\/span>idle<\/span><\/a> because they can perform their tasks only on the materials that have gone through the joining process.<\/span><\/p>\n

    On the other hand, the cutting and machining stations are still operational, so the inventory gets piled up.\u00a0<\/span><\/p>\n

    The failed joining machine caused a bottleneck and a delay in the production process. The result \u2014 a capital and operational efficiency loss.<\/span>[\/vc_column_text][\/vc_column][\/vc_row][vc_row kd_background_image_position=”vc_row-bg-position-top” css=”.vc_custom_1687440273251{margin-top: 40px !important;}” el_class=”limble-page-blog-width”][vc_column][vc_column_text]<\/p>\n
