Programming a turret punch press Amada is a critical skill for fabricating custom metal parts with precision and efficiency. The Amada turret punch press is a sophisticated CNC machine widely used in sheet metal fabrication to punch various shapes and holes by automatically selecting tools from its turret. This comprehensive guide will walk you through the entire process of programming an Amada turret punch press, covering everything from the basics of the machine and tooling to G-code programming, setup, operation, and troubleshooting. Along the way, we will include illustrative images and video references to enhance understanding. By the end of this article, you will be equipped to program your Amada turret punch press effectively for custom metal parts production.
The Amada turret punch press is a CNC-controlled metal forming machine designed to punch holes and shapes into sheet metal. It features a rotating turret that holds multiple punch and die tools of various sizes and shapes, allowing quick tool changes during operation.
- Turret with Multiple Stations: Typically, Amada turret punch presses have 31 to 72 stations, each holding a different punch tool. For example, the Amada Pega 357 model has 58 stations with auto-indexing capabilities.
- Fanuc CNC Control: Most Amada machines use Fanuc CNC controls like the 18P or 04PC, which allow precise programming and automation.
- Sheet Size and Thickness: Machines can handle large sheets (up to 50" x 144") and punch various materials including steel, stainless steel, aluminum, brass, and copper.
- Auto-Indexing Turret: Enables the turret to rotate and select the correct tool quickly, reducing cycle time.
- High Punching Force: Depending on the model, forces range up to 33 tons, allowing punching of thick materials.
Before programming, ensure you have the following ready:
- Part Drawing: A detailed CAD drawing of the metal part to be fabricated.
- Tooling Setup: Confirm the turret is loaded with the correct punches and dies matching the part design. If tooling is missing, it must be fabricated or sourced.
- Material Specifications: Know the sheet metal type, thickness, and size.
- Machine Parameters: Verify machine settings such as sheet clamping positions, turret configuration, and control system version.
The turret holds various punch tools. Each tool has a station number and specific shape/size.
- Standard Punches: Round, square, rectangular punches in sizes like 1/2", 1-1/4", 2", 3-1/2" diameters.
- Specialty Tools: Louvers, dimples, nibbling tools for complex shapes.
- Auto-Index Stations: Some turrets have stations that rotate the tool for angled punching.
- Keep turret, die holders, and tooling clean and lubricated to avoid wear.
- Assemble punch bodies carefully, using recommended grease and tools to avoid damage.
- Sharpen cutting edges when dull to maintain punching quality.
Programming the Amada turret punch press involves writing G-code commands that control the machine's movements and tool actions.
- The machine uses an X-Y coordinate system to position the sheet under the punch.
- Coordinates are typically programmed in millimeters or inches with high precision (0.01 mm or 0.001").
- Use the tool number command (e.g., T204) to select the punch station.
- The turret rotates to bring the selected tool under the striker automatically.
- G90 for absolute positioning.
- G91 for incremental positioning.
- G25 and G27 for auto repositioning and auto functions.
- P command to punch at the current position.
- G04 for dwell time (pause) if needed.
- G50 to retract and end the program.
Here is a simplified example of a G-code program for punching holes:
gcode
O0001 (Program Number)
G90 (Absolute Positioning)
T204 (Select Tool Station 204)
X20 Y12 P (Punch hole at X20, Y12)
Y8 P (Punch hole at X20, Y8)
Y4 P (Punch hole at X20, Y4)
T201 (Select Tool Station 201)
X12 Y8 P (Punch hole at X12, Y8)
G50 (Program End)
M30 (End of Program)
This program moves the sheet to specified coordinates and punches holes using the selected tools.
Before running the program on the machine, simulate it using software like PunchSim or PunchSimPlus. These tools visualize the punching sequence and detect errors to avoid machine crashes or scrap.
- Transfer the G-code program to the Amada CNC control via USB or network.
- Load the sheet metal on the machine table and secure clamps.
- Verify tooling setup matches the program.
- Run the program in manual or automatic mode.
- Monitor the punching process for any issues.
After punching, parts often require secondary operations such as bending, welding, or finishing. Amada turret punch presses are typically part of a larger fabrication workflow.
To maximize the efficiency and capabilities of your Amada turret punch press, consider the following advanced programming techniques:
Nesting software can optimize the layout of multiple parts on a single sheet to minimize material waste. Many Amada machines integrate with nesting software that automatically generates efficient punching paths.
Some programs allow simultaneous use of multiple tools or quick tool changes to reduce cycle time. Programming must account for tool change times and turret rotation speeds.
Advanced CNC controls can track tool usage and alert operators when tools require sharpening or replacement, preventing poor-quality punches and machine damage.
Using macros allows repetitive punching patterns or complex shapes to be programmed once and reused multiple times, saving programming time and reducing errors.
Even with careful programming, operators may encounter issues during operation. Here are some common problems and solutions:
This can happen if the turret is not properly homed or if limit switches are dirty or malfunctioning. Power cycling the machine and manually rotating the turret to a non-auto index station before shutdown often resolves this.
Caused by incorrect tool offsets or worn tooling. Recalibrate tool offsets and inspect tooling for wear.
Ensure clamps are properly set and that the sheet material is flat and free of debris.
Check G-code syntax and ensure all commands are supported by your machine's CNC control version.
Programming an Amada turret punch press for custom metal parts requires a solid understanding of the machine's tooling, CNC control commands, and part design. By carefully preparing tooling, writing accurate G-code programs, simulating the process, and monitoring machine operation, manufacturers can achieve high precision and efficiency in sheet metal fabrication. The Amada turret punch press remains a versatile and powerful tool in the metalworking industry, capable of producing complex parts with speed and accuracy. Mastery of its programming and operation unlocks significant productivity gains and quality improvements in custom metal part production.
Use the T command followed by the tool station number (e.g., T204) in your G-code to select the desired punch tool. The turret will rotate automatically to position the tool under the striker.
Amada turret punch presses can punch a variety of materials including mild steel, stainless steel, aluminum, brass, copper, and some plastics, depending on the tooling and machine capacity.
Regularly clean and lubricate the turret, die holders, and punch tools. Check for tool sharpness and replace or sharpen dull tools. Proper turret alignment prevents uneven tool wear and poor punching quality.
Yes, software like PunchSim and PunchSimPlus allows you to simulate the punching sequence and detect errors before actual machining, reducing scrap and machine downtime.
Sometimes the auto-index station motor may keep turning or show errors. Power cycling the machine and ensuring the turret is rotated to a non-auto index station before shutdown can help. Checking and cleaning limit switches may also resolve the issue.
