01Initial Situation
SN Makine needed comprehensive automation for its machine drilling cord holes in pleated and honeycomb blinds and fly screens. In manual operation, hole counts, hole spacing calculations and processing steps were performed by hand.
Repeating these calculations for every product dimension limited production speed and made results dependent on operator data entry. The aim was to bring dimension calculation, positioning and drilling into one automatic machine-controlled flow.
02Applied Solution
The algorithm automatically calculates the required hole count and spacing from product length. Once the operator enters the product dimension, the system determines hole positions and the machine performs drilling automatically.
- Automatic hole count and spacing calculation from product length
- 0.01 mm motion precision with servo and stepper motors
- Automatic positioning and drilling
The motion system used servo and stepper motors and was developed for 0.01 mm motion precision. Manual calculation and processing steps were thereby transferred to machine control.
03Technical Assessment
Since hole count and spacing are derived directly from product length, calculations do not need to be repeated manually for each product size. The servo and stepper motor motion system applies the calculated hole positions with 0.01 mm motion precision.
An automatic remote job list transfer system was also added. Planning can send product dimensions from a computer to the machine in a single file; the system uses it to prepare the production sequence, and the operator simply produces the listed jobs in order.
04Implementation Result
Automatic dimension calculation, positioning and drilling made drilling four times faster than manual production. With job list transfer, operators no longer need to enter product dimensions or hole counts, reducing manual data entry errors to zero.
Machine manufacturing, automation, the algorithm and remote job transfer were completed. The video shows the drilling unit moving along the machine axis.

05Project Outcomes
“The dimension file sent by planning goes directly to the machine, and the operator simply follows the production sequence. Automatic calculation accelerated drilling and eliminated dimension entry errors.”
