G-codes are sometimes called cycle codes because they refer to some action occurring on the X, Y, and/or Z axis of a machine tool.

All contouring controls provide linear interpolation, and most controls are capable of both linear and circular interpolation. Helical, parabolic, and cubic interpolation are used by industries that manufacture parts which have complex shapes, such as aerospace parts and dies for car bodies.

The method by which contouring machine tools move from one programmed point to the next is called interpolation. This ability to merge individual axis points into a predefined tool path is built into most of today’s MCUs.

Technical-functional coatings are used with the task of fulfilling the tribological criticalities that occur in the normal use of fundamentally mechanical component.

The achievable colors (and reproducible without obvious deviations) include the following range with different shades: gold, black, palladium, champagne, copper, multicolor… and others.

Thermal evaporation

M or miscellaneous codes are used to either turn ON or OFF different functions which control certain machine tool operations.

The development of MCUs capable of circular interpolation has greatly simplified the process of programming arcs and circles. To program an arc, the MCU requires only the coordinate positions (the XY axes) of the circle center, the radius of the circle, the start point and end point of the arc being cut, and the direction in which the arc is to be cut (clockwise or counterclockwise)

Magnetron sputtering

We can coat various types of objects of different materials (titanium, stainless steel, iron, brass, zamak, aluminum) up to some applications in crystal, ceramic and carbon fiber. Depending on the color tone requested by the customer and the physical / mechanical characteristics to which the part must respond, we propose the appropriate type of coating.

Starting from different types of substrate (the composing material of the object to be coated) such as brass, zamak, aluminum, steel, titanium up to plastic, glass / crystal, ceramic, carbon fiber, various materials are deposited. Some of them are:

PVDcolor

– High surface hardness > 1.800 HV: > 1800 HV; – Reproducibility and stability of color and surfaces; – Non-toxic, hypoallergenic and biocompatible; – High resistance to wear, scratches, rubbing and corrosion; – High resistance to the aggressive action of atmospheric agents (eg salt spray, UV rays); – Resistant to acids, alkalis, solvents and in general to many products for domestic and industrial use; – Surfaces’ Metallic appearance without requiring a transparent coating to protect the colours;

We deposit titanium, zirconium, chromium, alloys in well-defined percentages of titanium, aluminum, chromium which, wisely mixed with technical gases to obtain oxides, nitrides and carbides, form superficial deposits of ceramic compounds with high standards of resistance. And in any case we dedicate resources for the study and implementation of new solutions.

Furthermore, the possibility of obtaining different types of colors, non-toxicity of the product and total absence of environmental impact of the production cycle complete its fundamental characteristics. The fields of application are essentially two: decorative and functional.

"PVD coatings (full form Physical Vapor deposition) are superficial metal coatings in the form of very very thin films (with thicknesses ranging from a few tenths of a micron up to more important values depending on the needs), deposited with highly innovative technologies.”

Linear Interpolation consists of any programmed points linked together by straight lines, whether the points are close together or far apart

Initially born as an application in the military field, it soon found confirmation in many other sectors as a quality alternative to common surface colours techniques (eg galvanizing, painting, etc.) solving some problems and increasing their quality and technical characteristics.

These types of combinations allow to obtain very high surface hardness (HV> 1800), resistance to salt spray, corrosion and aggression from atmospheric agents, products for industrial use (solvents) and household products (various detergents) above the common standards.

The most widely used fields of application are: tools in general, from insert plates to cutters, components and accessories for hot and cold molds such as pins, punches and dies.

Other codes such as F, S, D, and T are used for machine functions such as feed, speed, cutter diameter offset, tool number, etc.

Curves can be produced with linear interpolation by breaking them into short, straight-line segments. This method has limitations, because a very large number of points would have to be programmed to describe the curve in order to produce a contour shape. A contour programmed in linear interpolation requires the coordinate positions (XY positions in two-axis work) for the start and finish of each line segment. Therefore, the end point of one line or segment becomes the start point for the next segment, and so on, throughout the entire program.
