Control System for a Sidewinder Key Cutting Machine
A monitoring panel for a sidewinder key cutting machine that shows coordinates, tool parameters and the cutting path on one page, updated live during machining.
CHALLENGE
Challenge
The groove of a sidewinder key is a continuous curve, so the X and Y axes have to move very precisely. The operators also wanted to see where the cut currently is and what shape is being produced while machining.
SOLUTION
Solution
We built a cutting machine monitoring panel that puts machine coordinates, work coordinates, the parameters of each tool set and a graphic of the cutting path on one page, with the position updated live during machining. Engineering debug and record pages were added for maintenance.
EQUIPMENT
Equipment and Technology
- KEYENCE PLC motion control
- C# UI design
- Servo positioning
- HMI monitoring panel
- Cutting mechanism
RESULTS
Results
- Live XY coordinate display
- Cutting path shown graphically
- Multiple groove parameter sets imported from Excel
- Domino inkjet printer
- Production line integration
The cutting path is clear at a glance, parameters can be adjusted without touching the program, and changing key models is fast.
