Automatic Cutting Machine
An automatic cutting machine is a machine used in the cutting process of apparel production that automatically cuts spread fabric with blades or other tools based on marker data to cut out each pattern piece.

Definition and positioning within the process
An automatic cutting machine is a piece of equipment that reads pattern and marking data created by a computer and cuts the fabric. CAM refers to computer-aided manufacturing, and in clothing manufacturing, it is sometimes used to refer to the mechanism and process of automatic cutting.
The typical process involves pattern making, grading, marking, fabric roll, cutting, inspection, and sewing. The automatic cutting machine plays a crucial role in accurately reflecting the markings in the cutting process.
How to proceed with cutting
Before cutting, we check the width of the fabric, the length of roll sides, the grain, the pattern direction, the nap , and the location of any damage or stains. Based on this information, we create markings and determine the number of layers to stack and how to lay the fabric when spreading it roll .
During cutting, the condition of the blades, the stability of the grip, and the cutting order are adjusted according to the machine type and the fabric. After cutting, the quantity of parts, matching marks, cut edges, and any mix-ups of left and right pieces are checked before handing the work over to the sewing process.
- Ensure that the version numbers of the pattern data and the specification document match.
- For pattern, clearly define the pattern direction and the criteria for matching the patterns.
- For fabric that require unidirectional cutting, the direction of fabric roll should be kept consistent.
- The cut bundles will be labeled with size, color, lot number, and part name for easy identification.
Quality and fabric considerations
While automated cutting can efficiently produce identical shapes, cutting accuracy is not determined solely by data. fabric stretch, slipperiness, thickness, number of overlapping layers, tension during roll, and the condition of the cutting blade all affect dimensions and the quality of the cut edge.
When cutting knit or stretch fabrics while they are stretched, dimensional differences may occur after sewing. For fabrics with a wool surface, brushed fabrics, and pattern, the direction and appearance of the fabric can easily change, so checking the fabric roll method and marking is especially important.
Ordering and Practical Confirmation Items
When outsourcing cutting and processing, prepare the pattern data, marking data, specifications, fabric information, required quantity, delivery date, and inspection standards in advance. Confirm the data format, seam allowances, notches, and cutting instruction transfer methods with each outsourcing company.
Cutting techniques that avoid fabric defects, pattern matching, one-way cutting, handling of roll, and sorting of parts after cutting all affect yield and delivery time. It is important to conduct test cuts and preliminary checks to agree on finished dimensions and part contents before mass production.
Differences from similar terms
Cutting refers to the entire process of cutting fabric into pattern shapes. An automatic cutting machine is a machine that performs this cutting. roll is the process of stacking and spreading the fabric before cutting, and marking refers to the process of efficiently placing the pattern on the fabric.
While "cutting machine" sometimes refers specifically to an automatic cutting machine, it's a broader term that can also include machines for cutting paper, film, sheets, etc., depending on the applications. When placing an order, be sure to specifically confirm whether the machine is for automatic cutting of clothing fabric.
FAQ
What kind of data do you prepare before using an automatic paper cutter?
Generally, we prepare the finalized pattern data, grading data for each size, marking data, and specifications. In addition, we specify the fabric width, pattern direction, front and back, grain direction, whether one-way cutting is required, the required quantity, and the sorting method after cutting.
If it's an automatic cutting machine, can it also automatically match patterns?
The machine cuts according to the set data, but the feasibility and accuracy of pattern matching depend on the fabric pattern, roll condition, alignment method, and marking instructions. It is necessary to clearly define the reference position and tolerance range of the pattern in the specifications and to perform prior checks.
What are some precautions to take when automatically cutting stretch fabric?
If the fabric is roll and cut while still taut, it may shrink after cutting, altering the dimensions of the parts. To address this, we determine the appropriate conditions for the fabric characteristics by mitigating tension through roll, managing tension during roll , setting the number of layers, and verifying dimensions through test cuts.
