Design of an Universal Micro Radial Drilling Machine

Design of an Universal Micro Radial Drilling Machine

Micro-drilling processes have been widely used to produce micro holes such as micro dies and molds, fuel injection nozzles, watches, bearings and printed circuit boards etc. And it has more attention in a wide spectrum of precision production industries. Experiments are conducted to investigate the effectiveness of drilling processes by measuring the hole quality after micro- machining. Two aspects, location error and oversize of the hole, of drilling quality are measured. Depending on the type of drills and drilling processes, it may occur that the drill walks on the surface of the work piece before entering the part. Whirling of the drill edge at the time of penetration into the work piece degrades hole quality as well. In order to avoid whirling of drill bit on the surface of work piece, we require the high R.P.M machine. This high R.P.M will lead to drill hole easily in a sheet of nearly 4mm. in order to attain high R.P.M generally two systems are used and they are pulley system or gear ratio system. But here also required R.P.M are not obtained so we can use embedded systems for getting desired R.P.M. In this machine the arm acts similar to a robotic arm but in a manual way. There is a cross slide which gives the linear movement to the drilling machine which takes care of the depth of the hole required and a stroke length of 125mm can be achieved using the slide. Since the machine is manually set, the accuracy of the hole or point at which the hole can be drilled depends on the accuracy with which the machinist sets the end drill bit to the point. Once the drill bit is made to touch the pointer-marked on the work piece, then the machine is to be started, set to the required speed and the depth is given using the slide, which gives a linear motion to the drilling machine. The flexibility achieved using this machine is an added advantage to the machine. With multiple axes available we aim to achieve drilling at any position known to us or required in the given design. The measuring and accuracy in order to maintain perpendicularity of the drill is obtained using angular measuring instruments like spirit levels, protractors etc. The linear measurements are done using linear scales.

Design and Fabrication of Angular Drilling Machine

ABSTRACT: Now a day, machines are widely controlled by embedded system. To meet the need of exploding population economic and effective control of machines is necessary. Our project even is rotated to easily drill at any direction. So that job setting operation is not complicated as well as reduces the setting time for the operation. It also takes into consideration the most effective method of controlling the drilling machine by manually. Materials like wood, plastic and light metals can be drilled with this. The work piece is fixed on the work table, which is provided with a moving arrangement. The drilling machine is one of the most important machine tools in a workshop. In a drilling machine holes may be drilled quickly and at a low cost. The hole is generated by the rotating edge of a cutting tool known as the drill, which exerts large force on the work clamped on the table. As the machine tool exerts vertical pressure to original a hole it loosely called a “drill press”. Drilling is the operation of producing circular hole in the work-piece by using a rotating cutter called drill, the most common type of drill is the twist drill. The machine tool used for drilling is called drilling machine. The drilling operation can also be accomplished in a lathe, in which the drill is held in the tailstock and the work is held and rotated by a chuck. This angular drilling is performed for Different Angle Drilling in the working job. Indexing Plate and Up/down mechanism is available in this Angular Drilling Machine.

Design of Jig for Multihead Drilling Machine

Design of Jig for Multihead Drilling Machine

Over the past decades, manufacturing has made considerable progress. Different new machine tools, High- performance cutting tools and modern manufacturing processes are used in today's modern industries to make parts faster and better than ever before. Mass production has a demand of fast and easy method of positioning work for accurate operations on it. Jigs are production tools used to manufacture duplicate and interchangeable parts. Jigs are specially designed so that the large numbers of components can be machined identically, and to ensure interchangeability of components. The most common jigs are for drilling and boring operation and they differ as per size, type, and placement of drill bushes. Drilling jigs are used to machine holes in mechanical products. To obtain positional accuracy of the holes, hardened drill bushes or jig bushes are used to locate and guide the drill, reamers etc., in relation to the work piece. These guide bushes are not essen- tial but these prove to be economical and technically desirable as will be discussed ahead. The portion of the jig into which the hardened bushes are fitted is called bushes. Drilling jigs are ei- ther clamped to the work piece in which holes are to drill on the work piece is housed and clamped in the jig body. If more than one hole is to be drilled, the drill jig made to slide on the table of the drilling machine. Such a drill jig is moved by hand into the position under the drill so that the drill readily enters the bush. During the drilling operation, the jig is held by hand.

Programmable depth control drilling machine

Programmable depth control drilling machine

design & develop one special purpose-drilling machine, which can be used to drill the job with different depths programmed independently. These kinds of drill machines are very much required in the mechanical workshops, where it is essential for specific job applications. The machine is designed with a drilling motor, and the motor functions independently. Drilling depth of the motor can be programmed through the keyboard. The drilling motor is moved in vertical direction through power feed technology designed with stepper motor. The stepper motor used to move the drilling motor up & down directions is aimed to pull down the drill motor while drilling the hole over the job. Here some force is applied such that the machine can be able to drill the hole over light metal jobs. Since the project work is considered as prototype module, the stepper motor used here can apply a little force. To drill over heavy metals like MS, high power motor with suitable gear mechanism is essential.

Development and analyzation of linear positioning table for drilling machine

Drilling is a continuous machining process. Drilling is a cutting process that uses a drill bit to cut a hole of circular cross-section in solid materials. This forces the cutting edge against the work piece, cutting off chips (swarf) from the hole as it is drilled. Various cutting tools are available for drilling, but the most common is the twist drill. Wide varieties of drill processes are available to serve different purposes such as drilling, reaming, boring, counter boring, counter sinking, spot facing, trepanning and under cutting. The objective of this project is to optimize and analyze the linear positioning table for drilling machine to make it more effective and perfect to function. Furthermore, the methods that can be used are by installing the screw on the based part of the linear positioning table for drilling machine. For this linear positioning table easy to use, the scale reading will be design on it so that operator will easily mark the desired measurement to be drill. A simple and safe design is proposed to optimize and analyze this project which is expected to function efficiently. In conclusion, this linear positioning table will be able to ease the operator work which the operator only needs to clamp once for the entire drilling process.
