Operating CNC machining center, or CNC router, always need to set cutting tool and change cutting tool to meet manufacturing requirement.

“How to set and change the cutting tool in machining center?” is the common question.

The cutting tool setting

The tool setting point of CNC machining center is the reference point used to determine the position of workpiece coordinate system in the machine coordinate system after the workpiece is aligned and clamped on the machine.

Tool setting point can be selected on workpiece or clamping positioning element. There must be an accurate, reasonable and simple position corresponding relationship between the tool setting point and the workpiece coordinate point, which is convenient to calculate the position of the workpiece coordinate point on the machine tool (the machine coordinate of the workpiece coordinate point). The tool setting point should preferably coincide with the workpiece coordinate point.

Tool change point

Tool change point: the machining center has a tool magazine and an automatic tool change device, which can change the tool automatically according to the needs of the program. The tool change point shall be in the position where there is no collision and interference between workpiece, fixture, tool and machine tool during tool change, and the tool change point of machining center is usually fixed.

CNC milled workpiece

Horizontal tool setting (x, y coordinates):

(1) tool setting of lever dial indicator: the tool setting point is the center of cylindrical hole;

(2) tool setting with edge finder: round hole or datum edge

(3) adjust the cutter by touching the cutter or trial cutting.

Aluminum CNC Milling & Tapping Part

Tool setting in Z direction (Z coordinate):

(1) on machine tool setting: use Z-direction setter to set the tool.

(2) pre adjustment of external tools + on-board tool setting.

(3) tool setting by external tool setting instrument: measure the diameter, length, blade shape and angle of the tool.

(4) the problem of tool setting in multi position machining of horizontal machining center.

How does CNC Milling Work?

KYLT Precision CNC Machining — Mon, 11 Feb 2019 11:04:07 +0000

CNC milling is often referred to interchangeably as CNC machining, because both encompass a variety of operations that can be done within a CNC machining center.Equipped with vicious cutters, CNC milling is capable of producing almost any shape. Milling operations involve using multi-point rotary cutters to remove material from a work piece. Work piece materials ranges different from Plastic to Metals.

CNC milling operations have two types:

1.Face milling : it cuts flat surfaces into the work-piece and flat-bottomed cavities. The feed can be either horizontal or vertical.

2.Peripheral milling: Peripheral milling cuts deep slots, threads, and gear teeth.

CNC milling

Two ways of the work-piece be fed into the cutting tool:

1. Conventional milling involves feeding the work-piece against the cutter rotation. This is the recommended method for manual milling machines.

2. Climb milling, on the other hand, feeds the work-piece in the same direction as the cutter rotation. This is the preferred method for CNC milling.

Milling is best applied as a secondary process to an already machined work-piece. It helps to define features and serves as a “finishing coat”. Use milling as a secondary process to add features such as holes, slots, pockets, and contours.

KYLT has multiple tool-sets based on efficient cutters for Engineering- plastic or Ferrous / No-ferrous Metal material. The machine then rapidly mills parts out of the block in a subtraction manufacturing process that uses either 3 or 4 axis milling.

At KYLT, CNC milling also encompasses drilling, reaming, threading, tapping, and other operations, as they can be completed in the same setup.

CNC Milling Cost:

Wide range of potential milling applications makes CNC machining the most variable service KYLT offers. Requirements of Milled parts Tolerance, Surface finish or treatment, Part size, use of Tooling or Jigs and material properties can all directly affect pricing. Providing a 3D CAD file can generally reduce time spent quoting or programming.

CNC Milled Parts Surface:

Machined plastic parts show visible tool marks on surface. A suitable cut tools will improve the milled plastic parts surface.

Metal parts allow more finishing choices. Polishing, Painting, Powder coating, Anodizing, Plating can be done on metal milled parts.
